Control wires must be shielded/armored. Connect the
shield to the drive chassis with a clamp. Normally, the
shield must also be connected to the chassis of the
controlling device. (See the instructions for the specific
device.) In analog signals or connections using very
long wires, 50/60 Hz ground loops may occur because
of noise transmitted from the AC line. It may be nec-
essary to break the shield and insert a 100 F capac-
itor between the shield and the chassis.
Tightening torques, control cables
Control wires must be connected with a tightening tor-
que of 0.22-0.25 Nm.
Electrical installation, control terminals
See section entitled Grounding of shielded/armored
control cables in the VLT 2800 Design Guide for the
correct termination of control cables.
