INSTALLATION
5.1.
Precautions when Installing the Main Unit
• Install the EJ-210 in a location within the operation environment range (temperature and
humidity).
• Do not install the EJ-210 in a location below. This may result in equipment failure.
(1) Location subject to direct sunlight or near equipment that generates heat
(2) Hot location or location subject to severe temperature fluctuations
(3) Location with high levels of dust or humidity
(4) Location subject to shocks or vibrations
(5) Location with a chemical atmosphere or where equipment may contact chemicals, or
location subject to water splashing
(6) Location close to power transmission lines or near equipment that generates strong
magnetic fields
(7) Location subject to severe power supply voltage fluctuations
• Firmly secure the EJ-210 in a vibration-free position.
• Do not install the EJ-210 in a location subject to water, such as steam or condensation. Check
that condensation along steam piping cannot fall on the main unit of the EJ-210.
• During installation, do not touch circuit boards inside the main unit with bare hands. Take care
that no dirt or metal particles can enter the main unit of the EJ-210.
• When connecting the optional steam pressure sensor, install the EJ-210 in a location where the
wiring between the EJ-210 and steam pressure sensor does not exceed 2 m.
• The EJ-210 is designed for indoor installation only. To install it outdoors, take appropriate
waterproofing, dustproofing, and antifreezing measures, and avoid locations subject to direct
sunlight.
NOTE
The EJ-210 has the same installation dimensions as the MI terminal MT1-
200. If MT1-200 was connected to the boiler, the EJ-210 can be installed in
the same location.
CAUTION
Do not directly weld the EJ-210 to a column or wall. Arcs from welding, etc.
may damage internal electronic components.
CAUTION
Check the points below to confirm that the installation location meets the
required conditions. Installation in an inappropriate location may result in
equipment failure.
