When wiring the GS4 drive, the most common problems are connection to the wrong terminal or
poor wiring practice. Please be aware of the possible damage that poor wiring practice may cause
to your GS4 drive:
1) Screw terminals where the wire is not fully inserted or the terminal screw is not adequately
tightened may result in sparking or high temperature due to a high resistance connection�
2) If circuit boards in the GS4 drive have been modified, components on the affected boards may
have been damaged�
Solution:
Inspect all power and control terminal connections in the GS4 drive to ensure adequate wire
insertion. Do not attempt to disassemble or repair control boards in the GS4 drive.
