OVERVIEW
The following procedure is a supplement to other documentation
available for the IMPULSE•G+/VG+ Series 4 variable frequency
drive (VFD). This will guide the user in proper installation and setup
of the system.
Before using the VFD-controlled equipment, the operator shall
read the operating manual of the hoisting machine, shall be
trained, and has to know all hazards by operating of cranes, hoists,
or lifting devices.
When installing the system, be sure to follow good wiring practices
and all applicable codes. Ensure that the mounting of components
is secure and that the environment, such as extreme dampness,
poor ventilation, etc., will not cause system degradation.
Read this document thoroughly before attempting installation.
Refer to the technical manual available at:
www.columbusmckinnon.com/magnetek.
Step 1
Connect Motor and Line Power
The following figure shows the electrical connections for the input
power and motor terminals on IMPULSE•G+/VG+ Series 4 VFD.
Make the appropriate connections with power turned off. Follow
good wiring practices and follow all applicable electrical codes.
Ensure the equipment is properly grounded, as shown.
DANGER! DANGEROUS VOLTAGES ARE PRESENT
WHEN VFD IS ON. Improper wiring can cause bodily
harm and damage to the equipment. Before applying
power to the IMPULSE•G+/VG+ Series 4, ensure that all
protective covers are fastened and all wiring connec-
tions are secure. After power has been turned OFF, wait
at least 5 minutes until the charge indicator extin-
guishes completely before touching any wiring, circuit
boards, or components.
