Electrical connections

The power connections for the power supplies slightly differs. All units are powers by 24 V DC. A tolerance of -15% u to +20 % is possible. The ground connection has to be installed, too. The following figures show the different connection variations.

CX1100-0001 connections

This power supply unit has no I/O interface. Though it is connected via a 5-pin "Open Pluggable Connector". In older versions of the unit the lower inputs are labeled with UPS+/-. These inputs are not in use and must not be connected.
