Instructions for Wiring Connections
Make sure the power supply is OFF before carrying out work on the wiring
or inspections involving disassembly. If such work is carried out with the
power on, there is a danger that equipment may malfunction or electric
shock may occur, leading to injury or other accidents.
Make sure that wiring work requiring a special license is carried out only
by qualified personnel. If carried out by unqualified personnel,
overheating or short circuits leading to injury, fires, damage or other
accidents may occur.
Do not touch the terminals during transmission. Failure to observe this
precaution could result in such hazards as damage to the product,
malfunctions, electric shock or fire.
Wiring Cables
Be sure to use electrostatically-
shielded, polyethylene-insulated, vinyl-
sheathed control cables (CEVS 0.75 to
2 mm
2
, 2- or 3-conductor) or the
equivalent as input and output signal
lines.
Wiring Method
1) It is recommended that cables be routed through conduits.
NOTE: Be sure to route the power cable independent of the input and output
control cables.
2) Keep the cables away from other power cables or power circuits to prevent
inductive interference. If inductive interference is suspected, use devices such as
capacitors or surge suppressors where necessary.
3) Use spade terminals to ensure good electrical connections. The terminals for
connections are located on the rear of the unit.
