CAUTION
• Use the 2-core shield cables for transmission lines. 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.
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.)
• For wiring, use the designated power wire 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.
