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

capacitor between the shield and the chassis.
