Installation
● Before installing the GM, linking modules, and install
-
ing modules, be sure to turn off the power.
● Apply more torque than what is recommended to
tighten the screws can deform the case or cause other
damage.
Installation Location
This product is designed as open equipment under
the CSA/UL/EN 61010-2-201 standards. In order to
comply with these standards, install it as follows:
• Install the GM unit / GX60 in a panel with a door.
• The instrumentation panel or panel used for support must
comply with CSA/UL/EN 61010-2-201 or must be at least
IP1X (degrees of protection) and at least IK09.
• Install the GM/GX60 systems in a panel with a door or in
a location where can not touch the output terminal block
carelessly, when hazardous voltages(over 30VAC or
60VDC) is inputted into output terminal block.
Install the GM / GX60 systems in a panel with a door or
in a location where operator or any third person can not
operate the power switch carelessly.
If the power switch of GM/GX60 systems under
operation be turned on or off carelessly, it may result
the system down or injury.
Install the GM indoors in an environment that meets
the following conditions:
• Ambient temperature range between -20 to 60°C (but -20
to 50°C when any of the following
.)
When using GM10 (Optional, / C8) and GX90YD,
GX90WD, GX90XA-T1 (electromagnetic relay type),
GX90YA, GX90UT.
• Ambient humidity between 20 to 85%RH
No condensation should be present.
Note
Condensation may form when moving the GM from a low
temperature or humidity environment to a high temperature
or humidity environment, or when there is a sudden change
in temperature. Temperature or humidity changes may also
result in thermocouple measurement errors. In these kinds of
circumstances, wait for at least an hour before using the GM,
to acclimate it to the surrounding environment.
• Well-Ventilated Location
To prevent overheating, install the GM in a well-ventilated
location.
• Minimal Mechanical Vibrations
Install the GM in a location that has minimal mechanical
vibrations. Installing the GM in a location that is subject to
large levels of mechanical vibration will not only put added
stress on its components, it may also impede ordinary
measurement.
• Level Location
Install the GM in a level location so that it is not slanted to
the left or the right.
Do not install the instrument in the following kinds of places.
• Outdoors
• In Direct Sunlight or Near Heat Sources
Install the GM in a place that is near room temperature
(23°C) and that is not subject to large temperature
fluctuations. Placing the GM in direct sunlight or near heat
sources can cause adverse effects on the internal circuitry.
• Where an excessive amount of soot, steam, moisture,
dust, or corrosive gases are present
Soot, steam, moisture, dust, and corrosive gases will
adversely affect the GM. Avoid installing the GM in such
locations.
• Near Strong Magnetic Field Sources
Do not bring magnets or instruments that produce
electromagnetic fields close to the GM. Operating the
GM near strong magnetic fields can cause measurement
errors.
Installation Procedure
The GM can be installed on a desktop or floor, mounted on a
DIN rail, or mounted on a wall. Regardless of the installation
method, be sure to install it in an upright orientation.
