Step 8: Electrical Wiring
DANGER: The installation, service and replacement operations on aPower and aGate equipment must be done by installers
certified and recognized by FranklinWH.
Before starting any electrical work, please ensure that aPower is powered OFF to reduce the risks of electric
The Installation, wiring, maintenance, transportation or handling of aPower and aGate should only be done by
qualified personnel with personal protective equipment (PPE).
DANGER: Before starting any electrical work, please open the grid power supply breaker, generator input breaker, the solar
input breaker, the load breaker, and lock (“lock out”) the switches. If the switches can not be locked, please lock the
distribution box where the switches are installed. A warning sign “Equipment Servicing, Keep OFF” should be hung.
It is strictly prohibited to install, maintain, and handle FranklinWH equipment outdoors when adverse weather
conditions, such as lightning, rain, snow, or strong winds are present.
Please follow your local laws, regulations and standards when performing installation, wiring, maintenance,
transportation and handling operations. The safety instructions in this Guide are supplemental to the laws and regulations.
DANGER: The power cables should be wired following the sequence: the load side, the backup power supply side, and then
the non
-backup power supply side. If the other end of the cable can not be wired at the same time, a warning sign “In
operation. Keep OFF” should be hung.
aPower and aGate do not have any lightning protection features. Installers must configure lightning protection
equipment as the grid power supply runs into the house.
DANGER: Please follow the “Local Precedence” rule. Remote control shut off does not mean that the local circuits are safe.
Please decide whether your circuit is safe only by testing for voltage.
The electrical wires must be connected to the correct service legs: L1 and L2 cannot be misconnected.
Misconnection may result in
quipment damage or even personal injury or death.
•The cables conductor size and current capacity rated are listed in the standard NFPA70, Article 310 for connection L1, L2, N, and
Ground.
•Conductors, relied upon for the protective grounding and bonding system, must be sized to handle potential fault currents. If
insulated, the insulation must be green or green with yellow striped in color.
•Grounding conductors are sized following Article 250.122 of NFPA 70 or Rule 10-810 of C22.1.d. A field wiring terminal or lead
shall be rated for the connection of a conductor or conductors having a minimum carrying capacity rating of 125% of the rating of the
unit.
•The distance between the end of the connection point of a field-installed wire and the wall of the enclosure toward which the wire is
to be directed shall follow Table 312.6 (A) or (B) of NFPA 70.
•Cables selections are listed in the last table. Please be sure to coat stripped surfaces of aluminum cable with antioxidants.
•Cables selection must consider metal compatibility. Please refer to Figure F.1 of Appendix F in the UL9540 standard.
