1. Disconnect the mains fuse and attach a sign
warning against reconnection.
2. Connect the cable assembly terminals to the
corresponding connectors. The connectors are
coded so that only matching terminals can be
connected.
Connect 4 terminals to main lift, one terminal for
lifting table.
3. Feed the hydraulic supply lines and power cables
from below through the lower knock-out in the
control box and connect to the hydraulic power
unit (
→
Annex, Power unit operating instructions,
hydraulics diagram).
4. Check the voltage, current and power ratings on
the information plate. Make sure the approved
structural conditions for connecting the power
cables are in place.
5. Remove the motor connection box cover and
route a 4-core power cable through the cable
gland into the connection box accordingly.
12.2 Connect the lift power supply
•
A motor protection switch designed for rated
current and rated voltage must be fitted as over-
load protection. This must be provided by the lift
user (not supplied).
•
All leads/cables/hoses must be routed in cable
conduits. Trip hazards must be avoided in the
traffic and work zone.
•
All main switches must be switched to “O” when
working on the electrics of this machine. The
mains power supply must be disconnected at the
fuse box (disconnect the mains fuse) and isolated
to prevent accidental reconnection. A clearly vis
ible warning sign must be attached accordingly.
6. Establish a mains connection (
→
Fig. 45 and 46)
• Standard configuration with 400 V connection
(3
L
+PE): W2 – U2 – V2 bridge.
• Alternatively 3 x 230 V- connection:
Change the wiring on the transformer (
→
arrow, Fig.47) to 230 V.
Remove the six M5 nuts in the motor connection
box, bridge U1–W2, V1–U2, W1–V2 according to
the diagram and tighten the nuts again.
7. Make sure that the equipment is properly earthed.
Do not connect the earth conductor to gas, water,
or telecommunications installations.
8. Attach the motor connection box cover.
9 .Check the direction of rotation of the motor (see
also direction of the arrow on the motor). To do
so, close the control box, connect the mains
fuse, turn the main switch to "ON“ and push the
Up button. Reverse the polarity if the direction of
rotation is incorrect.
