connectors of identical colour (orange and
grey).
For the assignment, see “Wiring diagrams”,
page 93.
With electronic hoist limit switch: Insert the
connector on the hoist limit switch PCB.

GM2 M5x65 3x 4 Nm
GM2 M5x45 1x 4 Nm
GM4 M5x60 3x 4 Nm
GM4 M5x50 1x 4 Nm
GM6 M8x110 3x 15 Nm

Insert the bayonet coupling of the connection
cable and the bayonet connector of the control
cable. Due to a notch, the plug-in connections
will only fit together in one position.
Slide on and tighten the bayonet nuts.
ONLY FOR GM2, GM4 AND GM6
(GM6 WITH PLASTIC CHAIN BOX)
The illustrations show a chain box being installed
on the GM6 chain hoist. Installation on a GM2 or
GM4 chain hoist is very similar.
INSTALLING THE CHAIN BOX
Bolt SL safety clip
Chain box
Place the chain in the chain box.
Turn the chain box as shown in the figure
(slanted side facing outward).
Use the bolts to install the chain box on the
chain hoist.
─ For GM2: Use a bolt to fix the chain box to
the chain hoist.
─ For GM4 and chain box with one hole: Use
a bolt to fix the chain box to the chain hoist.
─ For GM4 and chain box with two holes: Use
a bolt to fix the chain box to the chain hoist.
Use the inner holes of the chain box. The
outer holes remain free.
─ For GM6 and plastic chain box: Use two
bolts to fix the chain box to the chain hoist.
Secure the bolts with the SL safety clips (1x
or 2x).
