2.7 INITIALIZING THE CONTROLLER
2.7.1 Initial Heating Cable Test
To minimize the risk of damage to the controller due to a heating cable fault, the integrity
of the heating cable should be verified by performing the commissioning tests detailed in
the appropriate product installation and operating manual. These manuals can be found
on nVent.com
These tests must be performed with the controller output disconnected. Once the cable
has been checked, it may be reconnected to the controller and power applied.
