3.2 - Control terminal blocks
• Check that the terminal block has been removed from its fixed holder (unplugged) before making any connections,
so as to avoid putting pressure on the card.
• The VARMECA 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.
Removable screw terminal block:
- Tightening torque = 0.3 N.m
- Max. cross-section = 1.5 mm
