INSTALLATION AND WIRING
MOUNTING THE CONTROLLER
The outline and mounting hole dimensions for the 1234 controller are shown in
Figure 2a, and for the 1236 and 1238 controllers in Figure 2b. These control-
lers 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.
It is recommended that the controller be fastened to a clean, flat metal
surface with four 6mm (1/4") diameter bolts, using the holes provided. A thermal
joint compound can be used to improve heat conduction from the controller
