Installation
Contactors CPP series – Installation and Maintenance Manual
Installing the CPP contactor with 1,200 A
and 2,000 A CP devices
CPP pre-charging contactors as built-in versions have a
special angeled mounting flange for direct integration
into CP main contactors.
For CP contactor types with 1,200 A or 2,000 A, the CPP
can be mounted directly on the base plate of the CP
main contactor.
X
Position the CPP (2) at the base plate (3) of the CP
main contactor (4).
X
Screw in the 2 fixing screws (1).
X
Tighten the 2 fixing screws (1) to a torque of
3.2 - 4 Nm.

Installing the CPP contactor with 600 A
CP devices or as stand-alone solution
CPP pre-charging contactors as stand-alone versions
have a special mounting flange for the installation at
a seperate mounting position (e.g. next to a CP main
contactor).
For CP contactor types with 600 A, the CPP can only be
mounted at a separate mounting position.
X
Ensure that the contact surfaces on the moun-
ting plate (3) and the bottom of the CPP (1) are
free from dirt and other contamination (e.g. metal
chips).
X
Position the CPP (1) on the mounting plate (3)
which is provided with mounting holes.
X
Screw the CPP (1) on the mounting flange to the
mounting plate (3) using 4 mounting screws M5
including washers (2).
-
In designs with the mounting holes implemen-
ted as threaded holes, screw the mounting
screws into the holes directly, not forgetting the
washers.
-
In designs with through holes, fit the moun-
ting screws and washers and tighten the screws
using suitable screw locking elements and nuts.
X
Tighten the mounting screws to the specified tor-
que, which depends on the strength class (min.
8.8) of the screws/nuts used.
