electronic input circuitry is fuse protected on both the hot and
neutral inputs using a replaceable eight amp fuse (see page 9). For additional
protection of this instrument, use of a surge protector is recommended.
The controller should be connected to a dedicated power branch (i.e., its
own wiring, GFCI circuit breaker, etc.). For best results, the ground
should be independent (true earth) not shared.
A switch or circuit-breaker, marked as the unit’s disconnecting device
should be included in the installation. It should be in close proximity to
the unit and be easily reached by the operator.
Pre-wired controllers are supplied with a 3-wire grounded power cord and 3-wire
grounded receptacle cords for all controlled line voltage outputs.
Plug is considered as mains power disconnecting device which shall be readily
identifiable and easily accessible.
