Electrical installation of the safety module
The supply voltages are supplied at a bus coupler and/or a power terminal and are supplied
to the safety module via the potential jumpers. Therefore, the electrical installation of the
safety module only involves connecting the actuators.
The actuators are connected via VersaPoint connectors and/or COMBICON connectors.
•
Wire the connectors according to your application. For the terminal point assignment,
please refer to Section "Terminal point assignment" on page 3-4.
•
Label all connections to prevent connections to the connectors being mixed up (for
VersaPoint connectors, see IB IL SYS PRO UM E user manual).
VersaPoint connectors
Observe the following points during installation:
–
Only use cables with a cross section approved for the terminal point (see Section
"General data" on page 11-1).
–
Observe the maximum permissible current carrying capacity of the VersaPoint
connectors of 4 A.
–
Protect the connectors from overload using a
4 A fuse.
–
Observe the current carrying capacity when selecting the cables.
To wire the VersaPoint connectors, proceed as follows:
•
Strip 8 mm off the cable.
•
For multi-strand cables, fit the stripped cable ends with suitable ferrules and ensure
that they are properly crimped.
•
Push a screwdriver into the slot of the appropriate terminal point (Figure 4-6, detail 1),
so that you can insert the wire into the spring opening.
GE Intelligent Platforms recommends using a SZF 1 - 0.6X3.5 screwdriver.
•
Insert the cable in the corresponding terminal point of the connector (Figure 4-6, detail 2).
Remove the screwdriver from the opening. This clamps the wire.

Connecting unshielded cables
During installation, always observe the instructions in Section "Electrical safety" on
page 1-2.
Take measures to prevent the incorrect connection, polarity reversal, and manipulation
of connections.
