Precautions when laying power wiring
Use round pressure terminals for connections to the power terminal
block.
Round pressure terminal
Power cable
When none are available, follow the instructions below.
- Do not connect wiring of different thicknesses to the power terminal
block. (Slack in the power wiring may cause abnormal heat.)
- When connecting cable which is the same thickness, do as shown in
the figure below.
- For wiring, use the designated power cable and connect firmly, then
secure to prevent outside pressure being exerted on the terminal
block.
- Use an appropriate screwdriver for tightening the terinal screws. A
screwdriver with a small head will strip the head and make proper
tighterning impossible.
- Over-tightening the terminal screws may break them.
• Use the 2-core shielded wires for communication cables. Never use
them together with power cables.
• The conductive shielding layer of cable should be grounded to the
metal part of both units.
• Never use multi-core cable
• As this unit is equipped with an inverter, to install a phase leading
capacitor not only will deteriorate power factor improvement effect,
but also may cause capacitor abnormal heating. Therefore, never
install a phase leading capacitor.
• Make sure that the power unbalance ratio is not greater than 2 %.
If it is greater the units lifespan will be reduced.
