1.2.1
Installation site
The ZR802G is weatherproof and can be installed both inside and outside (Construction:
Equivalent to NEMA 4X/IP66). It should, however, be installed as close as possible to the sensor
to avoid long cable runs between the instrument and sensor.
Select an installation site where the ambient temperature, humidity and power voltage are within
the limits of the instrument specifications as below. If the instrument is installed outside and
exposed to direct sunlight, a sun shade hood should be used.
Ambient Operating Temperature: -20 to +55ºC
Storage Temperature:
-30 to +70ºC
Humidity:
10 to 90% RH at 40ºC (Non-condensing)
Power Supply Voltage:
Ratings; 100 to 240 V AC
Acceptable range; 85 to 264 V AC
Power Supply Frequency:
Ratings; 50/60 Hz
Acceptable range; 47 to 63 Hz
Power Consumption: Max. 800 VA, approx. 330 VA for ordinary use.
Select an installation site that meets the following conditions.
• Mechanical vibrations and shocks are negligible
• No relay switch and power switch are installed close to the converter
• There is space for cable connection beneath the cable glands
• Not exposed to direct sunlight or severe weather conditions
• Maintenance is possible
• No corrosive atmosphere
The ZR802G can be mounted on a wall, pipe or panel when the mounting kit is ordered. For
dimensional information please refer to the User’s Manual IM 11M12G01-02EN.
