6 Commissioning
6.1 Contact assignment
If you have assembled the cables yourself, please note the following:
 Statutory EMC requirements also apply to the cable connec-
tions. Use only shielded connection lines with shielded plugs/
sockets.
 Reliably isolate all equipment connected to the extra-low
voltage inputs and outputs according to DIN EN 61140
to safeguard against dangerous contact voltages. For
example, use double or reinforced insulation according to
DIN EN 60730-1 or DIN 60950-1.
The two variants of contact module dier in the number of inputs and
outputs. Two 3‑pin circular connectors and a 15‑pin D‑Sub socket are used
as connections. The connector can be configured for an external system
according to the contact assignments listed below.
Refer to Ä Chapter 12 “Accessories” on page 27 for accessory information
on assembling connection cables.
6.1.1 Contact module with single input and output (NAMUR)
