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.
