three-prong outlet.
Precautions to Be Taken While Wiring the Power
Supply (Power Supply Suffix Code: 2)
Make sure to follow the warnings below when wiring the
power supply. Failure to do so may cause electric shock or
damage to the instrument.
● Wire the power cable to the power supply terminal,
making sure that the polarity is correct.
● Connect the power cables after checking that the
power switch of the GM90PS is turned OFF.
● Using other wires may cause abnormal heating or fire.
Wiring Procedure
1. Turn off the GM90PS power supply, and then remove the
transparent power supply terminal cover.
2. Wire the power cable to the power supply terminal, making
sure that the polarity is correct.
Use ring-tongue crimp-on lugs (for M4 screws) with
insulation sleeves. The recommended torque for tightening
the screws is 1.4 to 1.5 N•m.

Turning the Power On and Off
If the power switch of GM/GX60 systems under
operation be turned on or off carelessly, it may result
the system down or injury.
Check the following points before turning on the power
switch.
● The power cord or wires are connected properly.
● The GM is connected to the correct power supply.
If the input wiring is connected in parallel with another
instrument, do not turn on or off the GM or other
instrument during operation. If you do, measured values
may be affected.
Check the following points before turning off the power
switch.
● The GM10 is not accessing the external storage me
-
dium.
You can turn the power on and off using the power switch
on the front panel of the GM90PS.
A self-test takes place for a few seconds, and then the GM
will be running.

Connecting GX90EX Expansion Modules
The GX90EX is used to configure a multi unit system.
• For the main unit, link the GX90EX to the left end as seen
from the front of the unit.
• For a sub unit, link it next to the GM90PS.
Connect the GX90EXs of the main unit and sub units with
Ethernet STP (shielded) cables. Only cascaded connection is
supported.
Configuring the GX90EX Expansion Modules
Before setting the GX90EX dipswitches, turn off the unit.
