1227/37 CONTROLLERS
1227/37 Installation
The 1227/37 controller can be mounted in any position, but the location should
be carefully chosen to keep the controller clean and dry. If a clean, dry
mounting location cannot be found, a cover must be used to shield the
controller from water and contaminants.
The outline and mounting hole dimensions for the 1227/37 controllers are
shown in Figure 8. To ensure full rated output power, the controller should be
fastened to a clean, flat metal surface with three screws.
Although not usually necessary, a thermal joint compound can be used to
improve heat conduction from the case to the mounting surface.
