1. Check entire dock leveler pit for proper construction
according to certified pit drawings (publication 5563 or
5566). Check to be sure that the pit walls are square
and plumb. Check electrical service running to the pit to
assure it conforms with the correct location and voltage
for the junction box. Inspect the pit and remove all
loose trash and construction debris. See the installation
troubleshooting on page 14 if the pit varies from the
specification.

Place barricades around pit on dock floor and drive while
installing, maintaining or repairing dock leveler.
1. The control station, User’s Manual and dock bumpers
are attached to the sub frame of the dock leveler. The
maintenance strut has a plastic tie wrap holding them
to the subframe. Remove these items before placing
the leveler into the pit. Make sure the customer gets the
user’s manual and is properly trained.
2. Mount and wire push-button control station. See Fig. 2.
See wiring diagram on page 15 of this User’s Manual for
wiring information. Wires shown in dashed lines are field
connections.
3. Mount and wire a conduit box with a 120V grounded 5-
15R receptacle on the pit wall as shown in Fig. 3. Wire
receptacle per diagram on page 15.
4. If conduit must be installed (replacing an existing
mechanical dock leveler) do so at this time. Refer to the
conduit requirements on the pit detail publications 5563
and 5566 and powered dock leveler wiring diagrams
and typical installation drawings, Fig. 3 and powered
dock leveler wiring diagram on page 15 for electrical
requirements. Follow all applicable electrical codes and
standards.
Before installing the dock leveler, read and follow the
Safety Practices on page 3. Failure to follow the Safety
Practices could result in death or serious injury.
