Electrical installation (24 V DC)

DANGER!
Risk of explosion in an explosive atmosphere (explosive
atmosphere only in the event of a fault, since it is Zone 2)!
` Opening the hood or the housing in an explosive atmosphere
is only permitted when the device is isolated!
WARNING!
Risk of injury due to electric shock!
` Before reaching into the system (except for the Teach-In pro-
cedure in a non-explosive atmosphere) switch off the power
supply and secure it to prevent restarting!
` Observe the applicable accident prevention and safety regu-
lations for electrical equipment!
Risk of injury due to improper installation!
` Installation may only be carried out by authorised specialist
personnel and using the appropriate tools.
Cable gland:
→
Open the housing.
→
Prepare the connection cable for signals and power supply as
well as for the external initiator, if necessary.
→
Insert cables through the respective cable glands into the interior
of the housing.
→
Connect the wires to the terminal strips according to the pin
assignments described in "Fig. 4".
