WARNING
Before installing and wiring the VZ20X, be sure to turn the power off.
■
Installation site
Install at a site that meets the following indoor conditions:
・
Ambient temperature
When mounted on a DIN rail: -10 to 55°C
When installed on a desktop: -10 to 50°C
・
Ambient humidity
5 to 90% RH
Use the VZ20X in a non-condensation state.
Note
Condensation sometimes forms on the VZ20X when it is moved from a low temperature
and humidity site to a high temperature and humidity site, or when temperature changes
suddenly. This may also result in a measurement error when thermocouple input is
measured. In situations such as this, allow the VZ20X to acclimatize to the surrounding
environment for at least one hour.
・
Well-ventilated sites
Install the product in a well-ventilated site to prevent temperature from rising inside.
・
Sites with little mechanical vibration
Choose a site that is subject to little mechanical vibration. Siting the product in a
location subject to lots of mechanical vibration may not only adversely affect
mechanisms inside the product but also prevent normal measurement.
・
Level sites
When installing the instrument, ensure that the site is level and free of tilting on the
front and rear, and left and right.

Altitude 2,000 m or less
