INSTALLATION
3.4 Precautions before installation
CAUTION
DO NOT move the STP pump and the STP control unit while the STP pump is in operation.
Doing so may result in product damage.
CAUTION
Fasten the STP control unit to a rack to prevent a falling accident caused by earthquake.
3.4.1 Operating environment
The SCU-1600 should be installed in an area which meets the following requirements.
Be sure the ambient temperature of the control unit during STP pump operation:
Ambient temperature 0 to 40 ºC (32 to 104 ºF)
Ambient relative humidity 30 to 95 % (non condensing)
Environment An area free of exposure to direct sunlight, high humidity, dust, salty
air, dripping water, explosive or flammable gas, corrosive gas,
radiation, strong magnetic and electric fields, excessive vibration
and sources of electric noise
Installation condition Install and anchor the SCU-1600 horizontally (within ±10 degrees)
3.4.2 Insulation test
CAUTION
The varistor for the power supply line protection is installed in the SCU-1600. DO NOT perform the
insulation test with the varistor installed. Doing so may result in product damage.
DO NOT perform an insulation test on the SCU-1600. When performing the insulation test on your
equipment, ensure that you disconnect the SCU-1600 from the equipment that is to be insulation tested,
so that the test voltage is not applied to the SCU-1600.
