Wiring Requirements
WARNING
Do not disconnect modules or wires unless the power supply has
been switched off or the area is known to be non
-hazardous.
The
devices may only be
connected to the supply voltage shown on
the type plate.
The devices are designed for operation with a
Safety Extra-Low
Voltage. Thus, they may only be connected to the supply voltage
connections and to the signal contact with the
Safety Extra-L
ow
Voltages (SELV) in compliance with IEC950/ EN60950/ VDE0805.
WARNING
Substitution of components may impair suitability for Class
I,
Division 2
, and Zone 2. These devices must be supplied by an
SELV source as defined in Low Voltag
e Directive 73/23/EEC and
93/68/EEC.
