2 INSTALLATION
Insure all terminating connections are clean and tight to prevent arcing and overheating.
The controller must be installed in an area that satisfies all of the following conditions:
1. Dry: Avoid any location where water can contact the controller
2. Cool: Ambient air temperature between 30°F and 105°F (0°C and 40°C)
3. Ventilated: Allow at least 2 in (50 mm) of clearance above and below and at least 1 in (25 mm)
on each side for proper air flow.
