• Minimal mechanical vibrations
Install the GX/GP in a location that has minimal
mechanical vibrations. Installing the GX/GP
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 GX/GP in a level location so that it is not
slanted to the left or the right (however, the GX/GP
can be inclined up to 30 degrees backward for panel
mounting).
Note
Condensation may form when moving the GX/GP 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 GX/GP, to acclimate it to the
surrounding environment.
The GP20 may tip over if it is tilted more than 10
degrees, front and back.
Do Not Install the Instrument in the Following Places
• Outdoors
• In direct sunlight or near heat sources
Install the GX/GP in a place that is near room
temperature (23°C) and that is not subject to large
temperature fluctuations. Placing the GX/GP 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 GX/GP. Avoid installing the GX/GP
in such locations.
• Near strong magnetic field sources
Do not bring magnets or instruments that produce
electromagnetic fields close to the GX/GP. Operating
the GX/GP near strong magnetic fields can cause
measurement errors.
• Where the display Is difficult to see
The GX/GP uses an LCD screen, so it is difficult to
view the display from an extreme angle. Install the GX/
GP so that the user can view the display directly from
the front.
Installation and Wiring
Installation Location
Install the GX/GP indoors in an environment that
meets the following conditions:
• If hazardous external voltage (30 V AC or 60 V DC or
more) is applied to the output terminals of the GP10/
GP20/GX60, be sure to install it in a location where
people cannot touch the terminals carelessly or in a
panel.
• The GX10/GX20 is designed to be installed in an
instrumentation panel.
• 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:
• The GX10/GX20 is designed to be installed in an
instrumentation panel.
Install it in a location where people cannot touch the
terminals carelessly.
• To make the GP10/GP20 comply with the relevant
standard, support the parts of the device other than
the front-panel control area with an instrumentation
panel or the like, and install it in a location where
people cannot touch the terminals carelessly or in a
panel.
• Install the GX60/GM unit 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.
To make panel door lock for GX10/GX20
or install the GP/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.
When the power switch of GX/GP
systems under operation be turned on or
off carelessly , it may result the system
down or injury.
Careless operations can be avoided by
applying the slide lock.
• Well-ventilated location
To prevent overheating, install the GX/GP in a well-
ventilated location. For the panel cut dimensions when
arranging multiple GXs, see the next page. When
other instruments are installed next to the GX, follow
the panel cut dimensions to provide adequate space
around the GX. In the case of the portable type, we
recommend that you provide at least 50 mm of space
from the left, right, and top panels.
