1Electric connectionsWhen necessaryCheck the connection conditions.If there is any loosing, please tighten it.
2Storage battery

1) each season

2) When necessary

Check the battery voltage

For battery recharging, current-limit and constant voltage method should be adopted.

If a single battery has no sufficient power, please replace all batteries. To ensure sufficient battery power, please recover the power for the battery.
3Insulation resistance test

1) Each 1~3 years

2) After overhaul

The measured value should conform to the factory specification.Test before and after AC voltage-withstand test.
4AC voltage-withstand test

1) Each 1~3 years

2) After overhaul

Follow the related quality standards and regulations stipulated by authoritative units.

1) Voltage applying: phase-to-earth and between phases for switching-on.

2) Test voltage between phase, phase-to-earth and fracture should be the same.

5Five-prevent inspection

1) Each 1~3 years

2) After overhaul

The results should conform to the factory specifications.

Five prevents:

1) To prevent misoperation of switching on/off

2) To prevent switching on /off the isolator with equipment electrified.

3) To prevent switching on the earthing switch.

4) To prevent switch on circuit breaker with earthing terminal.
