CS-L2 bridge

■Overview

PS 405 and PS 407 load power supplies

The modules of the CS-L2 bridge are supplied with DC 5 V and DC 24 V by the PS 405 and PS 407 power supply modules via the backplane bus.

Depending on the input voltage, either the PS 407 (for

AC 120/230 V) or PS 405 (for DC 24 V) power supply module is required.

The power supply module is inserted in the subrack on the left. It is designed in a casing, and is cooled by natural convection. The front panel of the module contains:

•LEDs for display of correct output voltages, correct backup battery voltage, and internal fault

•Key for fault acknowledgment

•On/off switch for output voltages

•Battery compartment (hidden) for backup battery (not relevant to CS-L2 bridge)

•Switch (hidden) for activation of battery monitoring

•Power supply selector (hidden) for AC 120/230 V

•Power supply connection (hidden) with 3-pin plug
