PRE-INSTALLATION INSPECTION
1. Remove your hoist and the trolley from the crate.
2. If necessary, make the changes to your hoist’s voltage. (Refer to page 7.)
remember any voltage changes that are made in the hoist must be made in the
trolley’s motor panel. (The transformer in the hoist operates the hoist & the
trolley)
Trolley Dual Voltage Adjustment:
When opening the trolley’s crate, you will find that the trolley motor is not connected yet
to the panel that houses the trolley contactors. This is done for transportation and site
fitment purposes allowing the trolley to be separated completely during installation
without the cable hindering the installation onto the beam.
460v = Star Connection
230v = Delta Connection
Single Speed
On a single speed 460v Trolley you will have a short black cable from the trolley
enclosure with 3 wires marked U1/V1/W1, these will go into the gland on the trolley
motor and be connected to the corresponding U2/V2/W2 on the motor terminal strip.
If the main incoming voltage is 230v then the trolley needs to be reconfigured to a delta
connection as per the below chart.
