■ 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
