Connect the Power Cables in a 480 V System

For 4-wire systems:

Bonding jumper: Not connected
Technical/system earth: No local grounding electrode connected

For 3-wire systems:

Bonding jumper: Must be connected
Technical/system earth: A grounding electrode must be connected via the grounding electrode conductor.

Only applicable to high impedance grounding systems:
1. Remove the jumper cable between the PE busbar and the E terminal.
2. Connect an external impedance between the PE busbar and E terminal according to NEC 2014 article 250.36.
Connect the equipment grounding conductor/PE to the PE busbar.
Connect the input cables.
Only applicable to dual mains systems: Connect the bypass cables.
Connect the output cables.
Connect the DC cables to the battery+ and battery- busbars.
For systems without internal backfeed breaker BF2: Fasten the provided plastic fasteners on the bypass cables in four places at 30 cm intervals. Adjust the fasteners to the bypass cables so they are fitted tightly together.
For systems without internal backfeed breaker BF2: Fasten the provided plastic fasteners on the output cables in two places at 30 cm intervals. Adjust the fasteners to the output cables so they are fitted tightly together.
