GP-37W3 Series User Manual6

GP Installation

• High voltage runs through the GP. Never disassemble the

GP, otherwise an electric shock can occur.

• Do not modify the GP unit. Doing so may cause a fire or

an electric shock.

• Do not use the GP in an environment where flammable

gasses are present, since operating the GP may cause an

explosion.

WARNINGS

GP Installation

• Be sure to securely connect all cable connectors to the

GP. A loose connection may cause incorrect input or

output.

GP Wiring

• Ground the GP’s FG line separately from other units’ FG

lines. Putting these FG lines too close may cause an elec-

tric shock or unit malfunction. Be sure to use a grounding

resistance of 100

ΩΩ

Ω or less and a 2mm

or thicker wire, or

your country’s applicable standard.

• When wiring the GP, be sure that the rated voltage and

terminal layout are within the designated range. If the

voltage supplied differs from the rated voltage, or incor-

rect wiring or grounding is performed, it may cause a fire

or unit malfunction.

• Use only the designated torque to tighten the GP’s termi-

nal block screws. If these screws are not tightened firmly,

it may cause a short-circuit, fire, or GP unit malfunction.

• Be careful that metal filings and wiring debris do not fall

inside the GP, since they can cause a fire, GP unit mal-

function, or operation error.
