4.3 Connecting 2-Wire proximity switches
IMPORTANT
The below mentioned typical switch specifications
are applicable for non-hazardous areas.
1. Before connecting the switches, check the
model code on the Control Module label.
QCXX.xxxNxx = 2-Wire NAMUR proximity
2 Guide the cable(s) through the electrical
entry(ies).
- Use and mount cable glands as required by
national or local legislation.
3. Make connections as shown in figure 4.9 and
table 4.5.
