17) Connect the Lights and Controls
Locate the female TMA Socket Connector in a convenient location on the truck, so that lifting or
lowering the TMA will not damage the electrical cable. Make sure that the electrical cord on the
TMA can reach this location.
For support vehicles with combined tail and clearance lights, connect a jumper between pins 2
and 6 on the backside of the male TMA plug connector (see VIEW A-A Figure 20). Connect the
7-pin plug to the socket on the truck.
The truck battery must be of the proper voltage. The SS180 TMA
®
is available in 12 volt and 24
volt versions. Be sure the system and truck are compatible. Be sure to use standard safety
practices when attaching the battery cables (e.g. do not let the ends of the cables touch, etc).
Do not run the battery cables around sharp corners or metal work, or in other areas that would
pinch or cut the cables. Connect the battery cable to the pump motor (see the Hydraulic
Assembly in drawing package).
The controls at the rear of the truck shall be mounted to the Support Frame, on the non-traffic
side (side closest to the curb). If they are not, move the rocker switch to the other side by
compressing the four tabs on the back side of the switch towards the switch body. Securely
fasten cable ties to secure any loose wiring to the TMA frame. Mount the cab switch box inside
the cab within easy reach of the driver and plug in the cab switch box at the mating connector
of the TMA.
