Safety Precautions
AC Power Supply
The HGM-MZ 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 20 Watts. It is highly recommended that the monitor be connected
directly to the AC power source, preferably on its own circuit with UPS or surge protection.
 A switch or circuit breaker must be included in the building installation.
 The switch must be in close proximity to the monitor and within easy reach of the operator.
 The switch must be clearly marked as the disconnecting device for the equipment.
Protective Grounding
Under no circumstances should the HGM-MZ be operated without connection to 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.
Explosive Atmosphere
Do not operate this equipment in the presence of flammable liquids, vapors or aerosols. Operation of any
electrical instrument in such an environment constitutes a safety hazard.

Failure to do so may constitute a safety hazard.
Accessing the Interior of the Monitor

maintenance personnel should perform connections and adjustments. Always remove AC power before
opening the monitor’s enclosure.
