■ Safety Precautions
WARNING
Do not attempt to disassemble the Power Controller while the power is
being supplied. Doing so may occasionally result in strong electric
shock.
Do not touch any of the terminals while the power is being supplied.
Also, always attach the terminal block cover after completing wiring.
Touching live terminals may occasionally result in serious injury due to
electric shock.
Fail-safe measures must be taken by the customer to ensure safety in
the event of incorrect, missing, or abnormal signals caused by broken
signal lines, momentary power interruptions, or other causes.
Abnormal operation may result in serious accidents.
Do not use the Power Controller where subject to flammable or
explosive gas. Otherwise, explosion may occur.
Use the wire sizes given in this document and use twisted copper
wires or solid copper wire. Use crimp terminals with insulative sleeves.
If the crimp terminals do not come with insulative sleeves, attach
insulative sleeves. Use the size of crimp terminals specified in this
document.
Make sure that the phases match for load terminal T1 and power
supply terminal 4 (N), and for load terminal L1 and power supply
terminal 5 (L). Insert suitable fuses in the power supply line and load
output line to protect the circuits. The Power Controller will not operate
normally if the wiring is not correct, and the load may be damaged.
Leave at least 100 mm of space above and below the Power
Controller when installing it to allow heat to dissipate. Do not obstruct
the area around the Power Controller and especially the area around
the heat sink.
Install the Power Controller in the direction shown in this Instruction
Sheet. The Power Controller generates a lot of heat and it uses natural
heat convection for cooling. Installing the Power Controller in the
wrong direction may cause in malfunctions or accidents.
