14. INSTALLATION
WARNING
Prohibition against
unauthorized
installation and
electrical
engineering work
Never attempt any of installation work, electrical engineering, and any of the
jobs instructed to the engineering outfit ("For the engineering outfit"). All of
these jobs must always be commissioned to your engineering outfit because
they involve electric shock hazards, fire hazards and falling hazards.
14.1 Precautions on Installation
Selection of place of installation
WARNING
The Quartz Master Clock is designed for indoor use, and must not be
installed outdoors. Otherwise, rainwater may infiltrate into it to cause
electric shock or fire accident.
WARNING
It must not be installed in the bathroom or washing area or other electric
shock- or fire accident-prone damp places.
Select an installation place least susceptible to the influence of temperature, humidity and vibration.
The ambient temperature of the selected place should be held within the range of -10
℃
to +50
℃
.
Load-bearing capacity
WARNING
Make sure that the wall or other structure onto which the Quartz Master Clock
is to be mounted has a sufficient strength to bear up against its weight. If
the structural strength is not sufficient, it may yield to the weight of the
product or external shocks, letting it fall to cause fatal accidents.
Power supply
WARNING
Be sure to use only the rated voltage with the Quartz Master Clock. If any
other power supply than specified is used, an electric shock or a fire will be
caused.
Use an exclusive power supply as the clock system runs 24 hours a day, 365 days a year.
Electrical engineering work
WARNING
Before wiring the input/output terminal blocks, make sure that no AC voltage
is supplied, and that the battery is not connected. You are warned against
working on live circuits as they involve fatal electric shock hazards.
