Microtel Series 100 - Manual (Page 9)

E. ELECTRICAL POWER INSTALLATION
Electrical power may be applied by simply plugging the system into a grounded,
three wire outlet. BE CERTAIN THAT THE OUTLET HAS AN ADEQUATE EARTH
GROUND. INSUFFICIENT EARTH GROUND CONNECTIONS CAN HARM THE
UNIT AND PREVENT INTERNAL PROTECTION CIRCUITRY FROM PERFORMING
PROPERLY.
It is recommended that a separate circuit breaker be used with the system.
Remember that when the breaker is on, and the unit is plugged in, 120vac is
contained within the system even though the internal STANDBY/OPERATE switch
may be turned off.
If the unit is to be installed in a location where large or high voltage motors are in use
a power line transient suppressor is recommended to insure that the unit is not
affected by surges and spikes in the 120VAC power to the unit. If such a device is
needed, contact Microtel for assistance.
The internal system fuse is a 1/4 amp fuse (Littlefuse #312.250), or equivalent.
WHEN INSPECTING OR REPLACING THE FUSE, YOU MUST UNPLUG THE
SYSTEM OR THROW THE CIRCUIT BREAKER SUPPLYING POWER TO THE
UNIT.
