Connection

Danger!
Danger to life from incorrect installation
Incorrect installation of cables and connection lines can compromise the function
and the electrical safety of the device.
• Observe the permissible core cross section of the conductor.
• When using stranded conductors, crimp wire end ferrules on the conductor ends.
• Use only one conductor per terminal.
• When installing the conductors the insulation must reach up to the terminal.
• Observe the tightening torque of the terminal screws.
Danger!
Explosion hazard from missing cover
Contact with bare parts that are energized can cause sparks, which can ignite an explosive
mixture.
Make sure that all bare, conductive parts are fitted with a cover that is rated with the degree
of protection IP30 according to IEC/EN 60529. Make sure that screw terminals have terminal
covers and unused terminal openings have terminal pins.

Connecting Multifunction Terminals
1.
Remove the insulation from the conductors to a length of 9 mm.
2.
If you are using stranded conductors, make sure that these are fitted with wire end ferrules.
3.
Insert the conductors in the opening of the multifunction terminal. Note that the conductor
insulation must reach up to the terminal.
4.
Make sure to use separation intervals between current circuits according to IEC/EN 60079-14.
5.
Tighten all the screws on the screw terminals to a tightening torque of 0.5 Nm to 0.9 Nm.
This is valid for unused terminal openings too.
