Installation
Pre-installation Information
If the controller has not been removed from its shipping carton, inspect the carton for damage then remove the controller.
•Inspect the unit for any obvious shipping damage and report any damage due to transit to the carrier.
•Make sure a bag containing mounting hardware is included in the carton with the controller.
•Check that the model number shown on the inside of the case agrees with what you have ordered.
