CAUTION
• Use the 2-core shield cables 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 deteri-
orate power factor improvement effect, but also may cause capacitor abnormal heating. There-
fore, never install a phase leading capacitor.
• Make sure that the power unbalance ratio is not greater than 2%. If it is greater the units lifes-
pan will be reduced.
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.
