LCD is harmful to the skin. If the LCD is broken and the liquid gets
on your skin or clothes, wash the liquid off using soap, and consult
a doctor immediately.
•
Emergency stop circuits must be configured outside the HG1H/
HG1T by using its emergency stop switch.
•
Connect the equipped emergency stop switch and enabling
switches to the HG1H/HG1T so that they work in the stop cat-
egory "0" or "1" in accordance with EN60204-1.
•
The D-sub connector provided with the HG1H/HG1T cable is not
a water or dust-proof type. If you need a water and/or dust-proof
connector, apply a waterproofing treatment to the inlet of cable
connector or replace it with a D-sub connector that is waterproof.
•
When using the HG1H/HG1T, make sure to securely place your
finger on the enabling switch.
Caution
!
•
Use of the HG1H/HG1T at high temperature and humidity, with
condensation, corrosive gas, excessive vibration, and/or shocks
may cause electric shock, fire, and/or malfunction.
•

It may cause failure and/or breakage of the unit.
•
Connect the unit to a power source with a suitable rating. Improp-
er connection may cause a fire.
•
For wiring, select a suitable wire for the applied current and volt-
age.
•

Instructions
•
Installation environment
In consideration of the product performance and safety, avoid in-
stalling the unit in the following locations:
•
Where there is a high level of dust, salt air, or iron particles
•
Where oil or chemical splashes occur
•
Where direct sunlight falls on the unit
•
Where a corrosive gas or flammable gas exists
•
Where the HG1H/HG1T unit is subjected to vibration or shock
•
Where condensation occurs due to rapid temperature change
•
Where high-voltage devices or arc-generating equipment (such
as electromagnetic switches, no-fuse breakers, etc.) are located
nearby.
•
Operating environment
Take the following points into consideration when installing the
HG1H/HG1T on a wall.
•
Install the HG1H/HG1T so that it will not be exposed to heat
generated by other equipment.
•
If you plan not to operate the unit using your hands, mount it on a
wall or a stand. For wall mounting, use the mounting bracket on
the back of the HG1T. For the HG1H, use the optional wall mount
bracket (Type No.: HG9Z-HK1).
•
Do not apply direct force to the D-sub connector.
•
Installation of ferrite cores
When using the HG1T in environments where it is subjected to
a lot of noise, it is recommended that ferrite cores be attached
(ZCAT2436-1330: TDK Corporation, or equivalent) to either or
both ends of the cable.
