MOUNTING THE CONTROLLER
e outline and mounting hole dimensions for the 1232E/SE controller are shown in Figure 2a, for the
1234E/SE controller in Figure 2b, and for the 1236E/SE and 1238E/SE controllers in Figure 2c. When
an Ampseal plug housing is mated with the 35-pin logic receptacle, these controllers meet the IP65
requirements for environmental protection against dust and water. Nevertheless, in order to prevent
external corrosion and leakage paths from developing, the mounting location should be carefully chosen
to keep the controller as clean and dry as possible.
Mount the controller to a at surface devoid of protrusions, ridges, or a curvature that can cause damage
or distortion to its heatsink (the base plate). Secure the controller using four 6 mm (1/4") diameter bolts
evenly torqued to the vehicle’s mounting surface. ese controller’s heatsink (bottom surface) have a typical
roughness grade of N8 (ISO 1302), with a atness tolerance of < 5 mm (0.13 per 25 mm). A thermal joint
compound is recommended to improve heat conduction from the controller heatsink to the vehicle’s
mounting surface. Typically, when properly mounted to a larger metal surface, additional heat-sinking or
fan-cooling is not necessary to meet the application’s peak and continuous current ratings.
