Electrical Wiring
The HGMSZ 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 (14−18 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 on the inside of the monitor (Page 8) and secure the incoming AC power leads to the
GND, LINE 1, and LINE 2 terminals as shown in the diagram below.
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.

WARNING: Drilling holes in the HGMSZ enclosure will
void the warranty. Please use knockouts provided for
electrical 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: Connection of the mains wiring must be made
to terminals LINE1, LINE2, and GND. 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.
