Preface
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
Ω Ω Ω Ω Ω
or less and a 2mm
2
or thicker wire, or
your country’s applicable standard.
• Correctly wire 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 malfunction.
• Be careful that metal filings and wiring debris do not fall
inside the GP, since they can cause a fire, GP malfunc-
tion, or incorrect operation.
