5.2 Installation and assembly of the PSCBR module
The module is solely to be installed in control cabinets with a degree of protection of at least
IP54.
The modules must be vertically fastened on a top hat rail
The ventilation slots must be kept unobstructed, to ensure adequate air circulation inside the
module.
5.3 Installation of backplane bus system
Mounting several PSCBR modules (PSCBR-C-10, PSCBR-C-10-SDM1, PSCBR-C-10-SDM2,
PSCBR-C-10-SDM2A) on one top hat rail in connection with the backplane bus system is also
possible. These modules can be combined with a communication extension. In this case the
backplane bus system needs to be configured by Schmersal when placing the order and
delivered in accordance with the application in question.
The backplane bus system consists of a 5-pin plug connector with snap-in contacts. In these plug
connectors all 5 contacts are equipped by standard. In this case the component is not specially
marked. On a second variant of the plug connector only 3 contacts are equipped.
Note:
Expansion modules have no own power supply unit and depend on a DC power supply via the
backplane bus system. Base modules (PSCBR-C-10, PSCBR-C-10-SDM1, PSCBR-C-10-SDM2,
PSCBR-C-10-SDM2A) are equipped with a reinforced power supply unit and always feed in to
the backplane bus.
There are two different types of backplane bus connectors:
TB1:
Standard design (all contacts are present)
TB2:
Circuit breaker design (The two live conductors are not present and are
marked with a green dot.
Using the backplane bus connector TB1:
The backplane bus connector TB1 can only be installed in connection with expansion modules
without their own power supply. Connection of several standalone modules is not possible.
Using the backplane bus connector TB2:
The backplane bus connector TB2 is used for combining several base modules with expansion
modules. A detailed description can be found under point 4.3.1.
