DANGER
Hazardous voltage
Electric motors have high voltages. When incorrectly handled, this can
result in death or severe injury.
Switch off the machine so that it is in a no-voltage condition before you
open the terminal box.
NOTICE
Damage to the terminal box
If you incorrectly carry out work on or in the terminal box, this can result in material
damage. You must observe the following to avoid damaging the terminal box:
Ensure that the components inside the terminal box are not damaged.
•
It must be ensured that there are no foreign bodies, dirt or moisture in the
•
terminal box.
Close the terminal box using the original seal so that it is dust tight and water
•
tight.
Use O-rings or suitable flat gaskets to seal entries in the terminal box (DIN

6.1.1.1 Connection with cable lug for explosion-protected
machines
WARNING
Short-circuit hazard
Live conductors released from the terminal board can cause short circuits. Death or
serious injury can result.
You must bend single-core line conductors into a U shape in order to prevent
•
the contact force being transferred at just one side.
In order to prevent the cable lug from rotating, for a line connection using a
•
cable lug, angle single- or multi-core cables downwards through an angle of
approx. 40°.
