5.6 DC Output for Model 030-851-20 (maximum 3600kW)
5.6.1 Chassis and Site Ground Connections
WARNING: For safety reasons, ensure the system is properly bonded to the building’s ground grid.
This power system is suitable for installation as part of a Common Bonding Network (CBN) and is intended
to be used in a DC-C configuration (common DC return). In this configuration, both the shelf chassis ground
(via power system chassis ground) and common return shall be connected to the building master ground
bus (MGB) or floor ground bus (FGB), in a larger building, to ensure correct operation of the system and to
prevent drifting floating analog (especially current) readings.
The chassis is connected to the MGB via mounting brackets.
5.6.2 DC Output to Loads
DC output connections are made at the distribution module at the front of the shelf.
CAUTION: Make sure the applicable fuse has been removed before unplugging the corresponding
connector.
1. To connect a DC output cable, use needle nose pliers to pull out the appropriate plug-in connector. Apply
gentle clamping force to the pliers to avoid breaking the connector.
