WARNING
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
• NEVER touch a live power terminal. Doing so could cause an electrical shock or a machine malfunction.
• Do not use voltage beyond the GP unit's specified range. Doing so may cause a fire or an electric shock.
• Do not disassemble or modify the GP unit. Doing so may cause a fire or an electric shock.
• Do not operate the GP in an environment where flammable gases are present since it may cause an
explosion.
• Do not allow water, liquids or metal fragments to enter inside the GP unit’s case, since they can cause
either a malfunction or an electric shock. The allowable pollution degree is 2.
• To prevent electrical shock or equipment damage, unplug the GP unit's power cord from the power supply
prior to installing or wiring the GP.
• The GP unit's wiring should be checked to confirm that both the operating voltage and wiring terminal
locations are correct. If either the voltage or the wiring terminal location is incorrect, it can cause a fire or
accident.
• Be sure to use only the designated torque to tighten the GP unit's terminal block screws. If these screws
are not tightened firmly, it may cause a short-circuit, fire or incorrect unit operation.
• Be sure that metal particles and wiring debris do not fall inside the GP unit. They can cause a fire, mal-
function or incorrect unit operation.
• To prevent an electric shock, be sure to disconnect your GP unit's power cord from the power supply
before wiring the GP.
• Be sure to ground the GP unit's FG wire separately from other equipment FG lines. Also, be sure to use a
grounding resistance of 100
Ω or less and a 2mm 2
(14 AWG) or thicker wire, or your country’s applicable
standard. Otherwise, electric shock or malfunctions may result.
• To prevent an electrical shock, unplug the GP unit's power cord before either cleaning the GP or attaching/
detaching the power terminal attachment screws.
• Do not connect or disconnect Host and GP unit communication cables while the GP is turned ON.
Failure to follow these instructions will result in death or serious injury, or unintended equipment
damage.
