Connecting hoist to power supply
1
2
The hoist is delivered with a short (temporary) power
supply cable that is attached to the power socket.
Remove the cable from the socket and open the cable
gland. Remove the power supply cable.
*NOTE: The short power supply cable that is attached to
the power socket at the delivery of the hoist is only a
temporary cable. Never connect the hoist to the power
supply using this cable. Remove the cable and replace it
with the main power supply cable on the site before
connecting the hoist to the power supply.
Place the main power supply cable through the cable
gland and the cable entry to the connector and connect
the wires to the plug.
3-phase hoists
Pay attention to the order of the wires to ensure the
correct phase sequence:
• Connect the power control board (PCB) connectors
L1/L2/L3 with the phases 1/2/3 according to the correct
phase sequence.
1-phase hoists
• Connect the power control board (PCB) connector with the
phase L according to the information given in the sticker
for the 4-pole plug:
N-N-L-GND
(N = neutral, L = phase,
GND = grounding).
All hoists
•
Connect the (yellow/green) grounding wire with
grounding (GND).

Slide the power supply cable assembly in place and
connect the power plug to the power socket.
3-phase hoists: Install the cover plate and secure the
fixation with the four screws. Tighten the screws to the
correct torque.
1-phase hoists: Install the capacitors, the profile
extension, and the hoist cover plate. For instructions,
see Removing and installing hoist covers.

For 3-phase hoists
: Check that the phase sequence is correct.
To check the phase sequence, test that all motions (upward and downward movement of the hoist) occur to the correct direction.
Test that the desired functions are activated when the controller buttons Up and Down are pressed. Check also that the traveling
motion directions correspond to the controller directions. If not, change the phase sequence.

All hoists
: Check carefully all connections.
