VLT® 2800 Series
Installation
■ Electrical installation, control circuitry
NOTE
Using unshielded/unarmored cable may not
comply with some EMI/RFI requirements.
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 necessary to break the shield and insert a 100 µF
capacitor between the shield and the chassis.
