Twist the connection cable. In case of extension of the connection cable, shield
the cable and connect it on both sides.
Protective earth is provided via the housing.
Wiring of an intrinsically safe braking resistor
Only intrinsically safe braking resistors permitted !
Only "intrinsically safe" braking resistors are permissible for this oper-
ation, since these resistors interrupt themselves at fault such as safety
fuse without fire risk.
