2 - Installation

After connection, ensure that the seals are firmly in place, and that the screws and cable glands are watertight to ensure drive protection. Clear any condensation from the drain holes at the bottom of the motor.

2.1 - General

The IntelliGear Plus is usually fitted to the gear and mounted to the machine with flange or foot mounting. The motor fan cools the whole assembly. Make sure that the ventilation air inlet is free of obstruction. The positions of the potentiometer/cable gland supports are specified at the time of ordering. However they may be reversed if

necessary.

3 - Connections

Connection with copper conductor only.

3.1- Control Terminal Blocks

Remove the terminal block from it’s fixed holder (unplugged) before making any connections, to avoid putting pressure on the card.

CAUTION: The IntelliGear Plus has a positive logic configuration. Using a drive with a control system which has a different control logic may cause unwanted starting of the motor.

The control circuits in the drive are isolated from the power circuits by single insulation (IEC 664-1).

The installer must ensure that the external control circuits are isolated against any human contact.

If the control circuits need to be connected to circuits conforming to SELV safety requirements, additional insulation must be inserted to maintain the SELV classification.
