DEVICE
INSTALLATION
The supplied interlock device must be installed to prevent operation of the lift or vehicle when it is unsafe to do so.
The K-series lift provides an electrical interlock signal to the vehicle that prevents movement of the vehicle unless
the platform is fully stowed. The interlock control also supplies power to the lift only when the vehicle parking brake
is set and the transmission is in PARK.
NOTE:
An 8-amp circuit breaker is located within the lift as a circuit protection device. The circuit interface used
by the installer must be capable of carrying an additional 8 amps of continuous current.
Refer to
Figure 2-12
. The interlock installation kit provides a display panel for mounting on the vehicle dashboard.
The figure shows an LED display panel. The Lift Power LED lights green when the vehicle transmission is in PARK
and the parking brake is set. While the LED is green the lift is lowered and the platform can be deployed. The Not
Stowed LED lights red when the platform is not fully stowed into the vehicle. While the LED is red the transmission
cannot be shifted out of PARK.

The installer must verify that none of the original equipment circuit breakers, fuses, or solenoids are bypassed, re-
moved, or altered. Be sure that no wires are left frayed or hanging loose after installation of the interlock device. If
you have any questions concerning the proper installation of this interlock device, please contact our Product Sup-
port department.
