IntelliGear Plus™ Variable Speed MD Gearmotors

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. 

3 - Connections
Connection with copper conductor only.

•

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.

This terminal block is used to connect the 3 phase

 

power supply when the RFI filter is not used in an

 

IntelliGear Plus. Otherwise, the RFI filter output    

 

is screwed onto this connector and the power  

 

 

supply should be attached to the terminals located  

 

on top of the filter. (See table below)
