For your safety
WARNING!
Loss of safety function due to manipulation of the interlocking device
Manipulation of the interlocking device may lead to serious injury and death.
– You should prevent any possibility of the interlocking device being
manipulated through the use of a spare actuator.
– Keep the substitute actuator in a safe place and protect it from unau-
thorised access.
– If spare actuators are used, these must be installed as described in
Installation [
13]
.
– If the original actuators are replaced with substitute actuators, the ori-
ginal actuators must be destroyed before disposal.
}
Switch off the supply voltage before disconnecting the safety switch from the supply
voltage.
WARNING!
Ignition spark from cable separator/connector within the potentially
explosive area can trigger an explosion
When the cable separators/connectors are used within the potentially ex-
plosive area, sparks can be caused and lead to an explosion.
– Make sure that the cable separators/connectors are used only within
the potentially explosive area.

The IP protection type (see
