Installation and debugging


1. Firstly, confirm PZ30 Circuit Breaker box installation site without explosive, corrosive gas or dust.
2. Confirm PZ30 distribution box installation site without violent vibration, enough height from the ground should be confirmed.
3. Confirm the ambient temperature at -5℃~40℃, at normal temperature, relative humidity is not more than 90%, no condensation; if the environment temperature and humidity exceeds this requirement, need to design a special switch control cabinet. Or take some measures to use.
4.Supply voltage between -10%~+10%.
5. Altitude is not more than 2000 meters.


1.Preparation before commissioning: confirm whether the cabinet surface is damaged, whether the insulation is affected; confirm whether the cabinet is dry and clean; confirm whether the cabinet wiring looses and sheds; whether the cabinet has excess thread or foreign body (such as wrenches, welding electrodes, small copper); check each bolt for looseness or collision; whether manual test mechanical interlock is reliable and accurate; check the electrical switch is good, should have no jamming phenomenon.
2.Cabinet control power supply, conduct simulation action test according to the electrical schematic requirements of equipment, test whether each control loops work properly, whether the design meets requirements. Power transmission with test power, electric on-off, to see whether the action is accurate or not.
