For correct performance of this product after long storage before use it is important that Inverter
Capacitors are reformed according to the guide below:
Note 1: Rated voltage: please refer the rated voltage according to model label of inverter.
3.3.1. Main Considerations
3.3. Wiring Guidelines
3.2.4 Capacitor reforming guide after long storage
1. Tightening Torque for Screw terminals : Refer to the tables 3-1, when using a screwdriver or
any other suitable tools to make connections.
2. Power terminals:
Single phase : L1 (L), L3 (N)
Three-phase 200V models: L1 (L), L2, L3 (N)
400V models: L1, L2, L3
3. For all cabling use copper wires and the cable size shall be according to the table below
rated at 105 degrees Celsius.
4. Power & Control cable Minimum rated voltage
240V AC system, 300V AC.
480V AC system, 600V AC.
5. Control cables should be separated from the power cables. Do not place them in the same
cable tray or cable trunking to prevent against electrical interference.
Storage time Procedure to re-apply voltage
≤ 1year Apply rated voltage(Note1) of inverter in the normal way
Between 1-2 years
Apply rated voltage of inverter to the product for one hour before using
the inverter
≥ 2 years
Use a variable AC power supply to
1.Connecting 25% rated voltage of inverter for 30 minutes.
2.Connecting 50% rated voltage of inverter for 30 minutes.
3.Connecting 75% rated voltage of inverter for 30 minutes.
4.Connecting 100% rated voltage of inverter for 210 minutes. Once
the procedures completed, inverter just can be used normally.

Supply power cable must be connected to TM1 terminal block, terminals L1 (L) and L3 (N) for
single phase 200V supply, L1 (L), L2, L3 (N) and L1, L2, L3 for three phase 400V supply.
Motor cable must be connected to TM1 terminals. T1, T2, T3.
Warning: Connection of supply line cable to terminals T1, T2 & T3 will result in serious damage
to the drive components.
