2AFC3-PW24030 amp switch

Input Load POWDER WATTS INSTALLATION INSTRUCTIONS PowderWatts.com WARNING: This switch should only be installed by a qualified electrician. This product requires handling of high voltage wiring. Please turn off your circuit breaker and follow instructions carefully. Turn off your circuit breakers and follow safety precautions in order to avoid fire, personal injury, or death. REQUIREMENTS: The PW240 communicates with the Powder Watts Smart Hub and this Hub is required for the smart switching operation of the PW240. WHAT'S IN THE BOX: PW240, Mounting lugs (2), Mounting screws (2), closure plugs (4) WHAT YOU'LL NEED: Phillips head #2 screwdriver, flat head screwdriver, voltmeter, non-contact voltage sensor, and pliers (optional). COMPATIBILITY: PW240 requires a 30 amp circuit with a minimum of 10 gauge wire and can support up to 8 gauge wire. Requires an upstream GFEP circuit breaker. RATING: TURN OFF YOUR BREAKERS: Turn off the circuit breaker. If breakers aren't labeled, turn off the master breaker. Before proceeding - confirm wires are not hot with both a voltmeter and a non-contact voltage sensor. PREPARE INSTALLATION LOCATION: Remove old device (such as a thermostat, timer, or switch, if applicable). Carefully disconnect wires attached to the existing switch or run wire to the installation location. DISASSEMBLE THE PW240: Open the clear cover and set the plastic bag aside. Remove the four screws from the black housing. Gently disconnect the ribbon cable that holds two assemblies together - the gang box (containing the high power electronic board) and top cover (containing the low power electronic board). ATTACH MOUNTING LUGS: Open the plastic bag that was set aside on the previous step. The plastic bag has lugs, screws, and closure plugs. Screw in the contacts to the rear of the closure housing. Gently mount the closure to your preferred location using the lug holes. To avoid damage to the metal or possible stripping, be sure not to over torque these screws. IDENTIFY & STRIP WIRES: You should see 3 types of wires in your wall: Line (Black) • Neutral (White) • Ground (Green or Bare Copper). Be sure your wires have a ½ inch stripped at the end of each wire. If using stranded wire, ensure that all strands are properly fastened to the connector. FEED INPUT CABLES THROUGH BOX: Route the input wire to the input terminals. Attach the supply (input) ground wire to the ground screw. Here is what the connection should look like: Ground INSERT WIRE AND TIGHTEN SCREWS: Insert wires into terminals. Tighten the screws to a proper torque value of 3IN/LB. Tighten the contact screws so that the wire stays in place. Be sure to also connect the ground wire by using the ground screw closest to the input contacts. Use a flathead screwdriver to tighten the terminal screws. INSERT HEAT CABLE WIRES: Insert stripped wire into terminal (recommended 0.32 in. or 8 mm). Use a #2 screwdriver to tighten to 16Ibg-in (1.8Nm). Tighten the contact screws so that the wire stays in place. To make feeding the heat cable wires into the box and controller easier, we recommend temporally twisting them all together, then folding them over back onto themselves fully about 4 inches up - this will result in a hook-like shape that you can then insert, twist and they will pop up though the channel. Please carefully wind all of the strands together using your fingers in a twisting motion. It is important to be sure that no strands of wire are hanging free and not secured by the screw/ lugs. Free strands of wire not secure can lead to shorts and are dangerous. Be sure to also connect the ground wire by using the ground screw closest to the load contacts. Use a proper• screwdriver to tighten the terminal screws. RECONNECT RIBBON CABLE AND REASSEMBLE: Reconnect the ribbon cable and screw the assembly back together using the (4) 2-inch screws that were removed during disassembly. SAFETY CHECK: Double check all wires, look for loose strands, and make sure all screws are tightened. POWER ON SYSTEM: Return to circuit breaker and turn on power. TEST YOUR PW240: Test PW240 by firmly pressing the power button. Green LED indicates the relay has been turned on. INSTALLATION COMPLETE!

Grid Connect Inc. FCC ID: 2AFC3-PW240, IC: 22503-PW240 Report Number: R2208033-DTS Page 17 of 98 FCC Part 15C/ISEDC RSS-247 Report FCC §15.247(i) §2.1091 & ISED RSS-102 - RF Exposure Applicable Standards According to FCC KDB 447498 D04 Interim General RF Exposure Guidance v01, Section 2.1 RF Exposure Test Exemptions for Single Source, 2.1.1 General RF Exposure Test Exemption Considerations RF exposure test exemptions provide means to obtain certification without the need of showing data (measurements, or analytical/numerical modeling) to demonstrate compliance. Hereafter, in this context, an RF source is referred to as “exempt RF device” in the sense that it is not required to show data demonstrating compliance to RF exposure limits. Test exemptions apply for devices used in general population/uncontrolled exposure environments, according to the SAR-based, or MPE-based exemption thresholds. 8 However, it is always possible, especially when the potential for exposure cannot be easily determined, that an RF exposure evaluation may become required according §§ 1.1307(c) and (d). As detailed in Section 2.1.2, the 1 mW and SAR-based test exemption conditions are in terms of source-based available maximum time-averaged (matched conducted) output power for all operating configurations, adjusted for tune-up tolerance, and at the minimum test separation distance required for the particular RF exposure scenario under consideration. This minimum test separation distance is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander. To qualify for SAR test exemption, the test separation distances applied must be fully explained and justified (typically in the SAR measurement, or SAR analysis report, according to KDB Pub. 865664) by showing the actual operating configurations and exposure conditions of the transmitter, and applicable host platform requirements (e.g., KDB Pubs. 648474, 616217, 941225) When no other RF exposure testing or reporting is required, a statement of justification and compliance must be included in the equipment approval, in lieu of the SAR report, to qualify for SAR test exemption. If RF exposure testing requirements for a specific device are covered in a KDB Publication, those requirements must be satisfied before applying any SAR test exemption provisions. For example, this is the case for handheld PTT two-way radios, handsets, laptops, and tablets, etc. 9 Finally, when 10-g extremity SAR applies, SAR test exemption may be considered by applying a factor of 2.5 to the SAR-based exemption thresholds. 2.1.2 1-mW Test Exemption Per §1.1307(b)(3)(i)(A), a single RF source is exempt RF device (from the requirement to show data demonstrating compliance to RF exposure limits, as previously mentioned) if the available maximum time- averaged power is no more than 1 mW, regardless of separation distance. This exemption applies to all operating configurations and exposure conditions, for the frequency range 100 kHz to 100 GHz, regardless of fixed, mobile, or portable device exposure conditions. This is a standalone exemption, and it cannot be applied in conjunction with any other test exemption. 2.1.3 SAR-Based Exemption Grid Connect Inc. FCC ID: 2AFC3-PW240, IC: 22503-PW240 Report Number: R2208033-DTS Page 18 of 98 FCC Part 15C/ISEDC RSS-247 Report A more comprehensive exemption, considering a variable power threshold that depends on both the separation distance and power, is provided in §1.1307(b)(3)(ii)(B). This exemption is applicable to the frequency range between 300 MHz and 6 GHz, with test separation distances between 0.5 cm and 40 cm, and for all RF sources in fixed, mobile, and portable device exposure conditions. Accordingly, a RF source is considered an RF exempt device if its available maximum time-averaged (matched conducted) power or its effective radiated power (ERP), whichever is greater, are below a specified threshold. This exemption threshold was derived based on general population 1-g SAR requirements and is detailed in Appendix C. 2.1.4 MPE-Based Exemption An alternative to the SAR-based exemption is provided in §1.1307(b)(3)(ii)(C), for a much wider frequency range, from 300 kHz to 100 GHz, applicable for separation distances greater or equal to λ/2π, where λ is the free-space operating wavelength in meters. The MPE-based test exemption condition is in terms of ERP, defined as the 8 Specific test exemption thresholds for operations under occupational/controlled limits are not established. 9 When SAR evaluation is required by the hotspot mode or UMPC mini-tablet procedures, that is, where an antenna is ≤ 2.5 cm from a surface or edge, the test separation distance from the phantom to the antenna or device enclosure, as appropriate, should be applied to determine SAR test exemption for such configurations, according to the criteria in this document. For that case, the test separation distance cannot be determined from the distance of the antenna to the device surface or edge. According to ISED RSS-102 Issue 5 Section 2.5.1 Exemption Limits for Routine Evaluation-SAR Evaluation: SAR evaluation is required if the separation distance between the user and/or bystander and the antenna and/or radiating element of the device is less than or equal to 20 cm, except when the device operates at or below the applicable output power level (adjusted for tune-up tolerance) for the specified separation distance defined in table below, Frequency (MHz) Exemption Limits (mW) At separation distance of ≤5 mm At separation distance of 10 mm At separation distance of 15 mm At separation distance of 20 mm At separation distance of 25 mm ≤300 71 101 132 162 193 450 52 70 88 106 123 835 17 30 42 55 67 1900 7 10 18 34 60 2450 4 7 15 30 52 3500 2 6 16 32 55 5800 1 6 15 27 41 Grid Connect Inc.
