GM Energy V2H Bundle Installation Manual 48
• All conductors for each circuit have been torqued.
• All terminal lugs have been paint marked after each is torqued.
• Labeling of new and of any relocated conductors and/or circuits have been preserved and transferred correctly.
• Charger DIP switches are set, and Charger is properly labeled for its particular max. current rating.
Additionally, for installations that include the Charger and V2H Bundle, verify that the:
• Hub main breaker and bonding are installed correctly.
• CTs are correctly installed (or correctly re-located).
Best Practice: The same individual should properly torque and then paint mark all connections.
Verify Communications and Low-Voltage Wiring
For installations that include the Charger and V2H Bundle, proceed to Appendix G and print the System & Voltage
Checks (S&VC) form.
• Verify that all 12 VDC conductors are #10 AWG and terminated into the correct 12V and Ground terminals.
• Verify that all RS-485 and CAN cables are twisted pairs, are of adequate conductor size, and are wired into the proper
terminals.
• Verify that all control cables (DS, EPO, and RSD/ESD) are of adequate conductor size and are wired into the proper
terminals.
• After verifying these conductors and cables, check the appropriate boxes in the LV DC & Comm Cables section of the
form.
Measure and Record System Details and Voltages
Establish safe working zones and don PPE. Systematically energize the utility service to MSP/main breaker, premises
circuits, and Charger.
For installations that include the Charger and V2H Bundle, energize the Hub and the Inverter, and each circuit in the
Hub.
As equipment is energized, verify 120/240 V and Phase A / Phase B polarity, and record all system values and
measurements on the sheet. Compare L1/L2 current and power measurements from commissioning app to readings from
an external meter to ensure that the commissioning app is accurately communicating power consumption data.
