9.2.3.1 General
Application
External
c
modules are used for communication between the WL circuit breaker and the secondary equipment in the circuit
breaker panel. They are provided to control analog indications, transmit the circuit breaker tripping status and the reason for tripping
and to read additional control signals. Furthermore, with one of these modules it is possible to implement a zone selective interlocking for
short-circuit protection.

Installation
The external
c
modules are snapped onto a standard 35-mm DIN rail inside the switchgear panel. It must be ensured that the
length of the connecting cable of the first module to the circuit breaker does not exceed 6.5 ft.
Connection setup
The
c
modules must only be connected to each other and to the circuit breaker using the pre-assembled cables supplied.
These cables are also used for the 24 V DC voltage supply of the
c
modules.
If more than two
c
modules are connected, the 24 V DC voltage supply must be fed via a separate cable from module to module.
Only one
c
module can be connected directly to a circuit breaker. Further modules must be connected from module to module.
Radial cables are not permissible.
If provided, the ZSI module is always the first module, and must be connected directly to the circuit breaker.
The
c
cable must be connected to the X3 connection of the last module with a 120
0.5 W resistor.
The total length of the
c
cables must not exceed 30 ft from auxiliary current plug X8 of the circuit breaker to the last
c
module.
c
connections at module:
X3-1 = Ground 24V DC
X3-2 = CubicleBUS -
X3-3 = Cubi
X3-4 = +24V DC
c
connections at breaker:
X8-1 = CubicleBUS -
X8-2 = Cubi
X8-3 = +24V DC
X8-4 = Ground 24V DC
