Electrical Wiring

The HGM-SZ uses a universal power supply that is capable of accepting inputs of 100 to 240 VAC, 50/60 Hz.

The monitor’s power consumption is 15 Watts. It is highly recommended that the monitor be connected directly

to the AC power source, preferably on its own circuit. The connection should be completed with UL approved

multi-conductor wire (minimum 16 AWG), rated 300 VAC at 105°C.

Locate a convenient service knockout and install electrical conduit in the typical manner.

Locate the AC Input Terminals and Ground Stud on the inside of the monitor (Page 8).

Secure the incoming AC power neutral (white) and live (black) wires to the LINE 1 and LINE 2 terminals.

Using the supplied crimp-on ring terminals, washers, and nuts, connect the incoming AC power ground wire

(green) to the monitor’s AC Input Ground Stud, and then install a separate wire between the ground stud and

the GND terminal.

A switch or circuit breaker rated 1.0 A, 250 VAC, with a minimum terminal spacing of 3.0 mm must be attached

to the monitor’s AC power leads. This switch must also be located in close proximity to the monitor, and be in

easy reach of the operator. This switch should also be clearly marked as the monitor’s main AC disconnect

device.

AC Power Connections

WARNING: Electrical installation should be performed by a certified electrician, and

should comply with all applicable NEC/CEC and local electrical safety codes.

WARNING: The AC power ground wire must first be connected to the monitor’s ground

stud. Under no circumstances should this monitor be operated without a protective

ground. Doing so poses a potential shock hazard, and is also a violation of electrical

safety standards applicable to this type of equipment.

WARNING: Copper conductors for connection to supply mains must be made in

accordance with NEC/CEC and local codes

CAUTION: Drilling holes in the HGM-SZ enclosure may damage the unit and will void the

warranty. Please use knockouts provided for electrical connections.
