- Strip the conductor.
- Insert the conductor into the terminals and make sure that the conductor insulation
reaches right up to the terminals.
- Tighten the mounting screws of the terminals with 1.5 Nm.
- Insert the conductor into the cable duct (1) of the covering and fasten it by means of
the lug (2).
- Lead the conductor on the side of the switch in order to avoid crosswise wiring of the
auxiliary circuits to the main circuits.
WARNING
Danger caused by too short clearances and creepage distances!
Do not operate the Ex i auxiliary contacts without attached covering!
The customer is only allowed to install an intrinsically safe auxiliary contact if no pick-
off terminal blocks are mounted on the two terminals located on the left and right side
of the installation slot used!
Make sure that the customer does not install pick-off terminal blocks directly next to
the intrinsically safe auxiliary contacts!
