Installation and operating instructions
Flash code of power module
Cable lengths
Maximum permitted cable length 100 m for control signal 0-10 V DC and
fault signal contact.
Cabling
Leave a minimum gap of 20 cm between low voltage and power cables.
The connecting cables (not even the motor cables) need not normally
be shielded. In exceptional cases, for instance where cables are laid in
electromagnetically highly loaded or sensitive areas, it may be useful to use
shielded cables. In this case, one end of the shield must be connected to
the protective conductor.
Operating statuses
The operating statuses of the power module are displayed by the LEDs on
the power PCB.
