23. Accessories
23.1. POWER CONNECTION - POWER-BUS-BARS
These power-bus-bars are used to connect several PISA-B modules electrically together. The power-bus-bars distribute the
24V supply voltage of the PISA-B modules.
The length of 102mm is suitable to connect two PISA-B modules together. The length of 155mm is suitable to connect
three PISA-B modules together. If more than three modules need to be connected to another, appropriate pieces can be
cut from the 500mm long rail.
The supply of the 24V is then only done by one fuse module, preferably in the middle, because the current is then better
distributed in both directions and the permissible current of the power-bus-bars of 32A is not exceeded.
Fuse modules can be lined up on the DIN rail without spacing. The power-bus-bars can be plugged in from the front of the
PISA-B modules and must have a length that all plug contacts of the modules make a contact.
