5. ELECTRICAL WIRING

Controller must be wired in accordance with all applicable electrical codes.
Input power must be 120 or 220VAC Single Phase.
Trained service personnel are required for all electrical connections. This
product does not contain operator serviceable parts.
Devices attached to any Relay connection must be Single Phase and rated for
the same voltage as the input voltage to the product. (e. g. 120VAC MicroTrac
controllers support 120VAC relay attached devices exclusively and 220VAC
MicroTrac controller support 220VAC relay attached devices exclusively.)
Input power cord must be disconnected from power source prior to opening the
product's enclosure and making any electrical connections.
The controller should be connected to a dedicated power branch (i.e., its own
wiring, 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
easily reached by the user.
The MicroVision electronic input circuitry is fuse protected on both the hot and neutral inputs using
a replaceable five (5) amp fuse (Fig .6). For additional protection of your instrument, use of a surge
protector is recommended.
Pre-wired controllers are supplied with a 3-wire grounded power cord and 3-wire grounded
receptacle cords for all controlled line voltage outputs.
