Assembly
5.1
General
These assembly instructions enable the owner to install, re-install or replace the DC-Com unit himself. The owner
must appoint a coordinator who is authorised to issue instructions before assembly work commences.
Despite detailed information, errors cannot be excluded when the installation is assembled by the customer. For
this reason, we recommend that this work be carried out by our trained specialists or by persons authorised by
us.
The wiring of the Demag chain hoist complies in all respects with current DIN VDE and accident prevention regu‐
lations.
Unauthorised intervention and modifications eliminate compliance with these regulations.
DANGER
Live components
Danger to life and limb.
It must be possible to switch off the power supply by means of a device to disconnect the power supply (e.g.
mains connection or isolating switch with a padlock).
The chain hoists are supplied with power from an AC power network. The voltage and frequency of the AC pow‐
er network must match the data specified on the rating plate of the chain hoist.
