Electrical Connections
3.5.1
Ensure that the voltage of the electric power supply is proper for the trolley hoist.
3.5.2
Do NOT apply electronic soft-start control or voltage varying controls to the RHN
lifting or traversing motors. Use of such devices may cause the motor brake and other electrical
components to malfunction. For variable frequency drives contact Harrington for more information.
3.5.3
Before proceeding, ensure that the electrical supply for the hoist or trolley has been
de-energized (disconnected). Lock out and tag out in accordance with ANSI Z244.1 “Personnel
Protection -Lockout/Tagout of Energy Sources”.
3.5.4
Installing Power Supply Cord

and the wiring diagram provided with the Hoist.
2)
Remove Control Cover.
3)
Loosen the cable fitting located on the lower side of the electrical enclosure and insert the Power
Supply Cable. Pull through enough cable to reach the power supply terminal and securely tighten
the cable fitting.
4)
Connect the 3 phase power leads (L1, L2 and L3) and the ground lead of the Power Supply Cable
to the power supply terminal. Make sure the terminals are securely tightened and each lead is
completely isolated.
