2.2 Installation
2.2.1 General Precautions for Installation
Take the following precautions to prevent damage to ZM2371 / ZM2372.
• ZM2371 / ZM2372 is cooled by forced air-cooling.
Do not block the air inlet on both side panels and the air outlet on the rear
panel.
• The ZM2371 / ZM2372 must be installed horizontally (with the bottom panel
facing the floor). Using the device with the rear panel or side panel facing
downward (in the upright position) causes the device to be toppled down
easily, leading to a danger.
Handling of the panel and case
The front panel of ZM2371 / ZM2372 is made of plastic. It can be damaged by sharp or hot
tools. When the case/panel surface needs cleaning, wipe with a soft cloth. To remove
persistent contamination, wipe with a soft cloth soaked with neutral detergent and wrung
out. Do not use any organic solvents like thinner or benzene, or any chemical cleaning cloth,
as they may cause the surface finish to deteriorate, tarnish, or come off.
2.2.2 Installation Conditions
Install ZM2371 / ZM2372 in a location that fills the following temperature and humidity
requirements.
Operation: 0 to +40°C, 5 to 85% RH (where absolute humidity is 1 to 25g/m
3
,
non-condensing), 2000m or less (altitude)
Storage: −10 to +50°C, 5 to 95% RH (where absolute humidity is 1 to 29g/m
3
,
non-condensing)
Do not install the device in locations such as:
• location with direct sunlight or with a nearby source of heat
• location with significant amounts of dust, salt, metallic powders
• location with significant amounts of corrosive gases, vapor, soot
• location exposed to excessive vibration
• location close to a strong magnetic or electromagnetic field source
• location close to a pulsing noise source
If the measurement accuracy is important, warm up the device for more than 30 minutes
before use. Ensure adequate distance between power cable of ZM2371 / ZM2372 or other
devices and signal cable. The closest distance between the power cable and signal cable may
cause measurement dispersions due to a malfunction or noise.
