Six, the installation forms

Floor type (standard distribution cabinet)

 

 

 

 

 

 

 

Seven, PYS series design schematics

 

Option One: Single power supply schematic

Description:

1) When there is electricity, mains through KM1 output, maintenance-free battery charger for charging, when the EPS control circuit detects mains failure or mains voltage is too low, the inverter work to make KM2 pull the load powered by emergency power;

2) KM1, KM2 for electrical mechanical interlock within the EPS.

 

Option Two: act as a secondary supply dual circuit schematics

Description: EPS figure can serve as a connection to the second road load power, and the end of each vote, the inverter in this way when there is electricity in the state is not on, when there is no electricity emergency, immediately turn with output, this way each switch device outside the EPS.

 

Option Three: Dual power supply schematic

Description: The use of such wiring can achieve end load mutual investment level, EPS power to act as a third way, this way each switch device outside of the EPS.

 

Eight, PYS series wiring diagram (dotted line configuration are within EPS, EPS device set N, PE terminal strip or terminal respectively)

 

Option One: Single-supply wiring diagram

Wiring: persistent

Description:

1) KM1, KM2 for electrical mechanical interlock within the EPS;

2) output branch may be in the EPS, belongs optional.

 

Option Two: act as a secondary supply dual-circuit wiring diagram

Wiring: persistent

Description:

1) EPS inverter such programs when electricity is turned off. When there is no electricity, immediately went to work;

2) each switch device in addition to EPS.

 

Option Three: Dual power supply wiring diagram

Wiring: persistent

Description:

1) KM1, KM2, KM3 are within the EPS;

2) output branch may be within EPS.

 

Option 4: with multiple shutter doors connecting the wiring diagram

Description:

1) high-rise buildings are not at the same time start rolling doors, EPS capacity of not less than five times at the same time start rolling door motor capacity sum;

2) Due to shutter doors with very little power, so if the belt only when the shutter doors, the battery configuration can be reduced accordingly. General optional EPS capacity 20 minutes of standby time;

3) The EPS is as a way to power in the circuit, to provide emergency output in the absence of utility power.

 

Five programs: multiple elevators connected with the wiring diagram

Description:

1) The EPS just as the way the power in the circuit, to provide emergency output in the absence of electricity;

2) Elevator drive motor should have conversion function;

3) EPS capacity should lift the total capacity of 1: 1;

4) Use only PYS series EPS elevator work.

 

Six programs: with a pump connected with a prepared wiring diagram

Description:

Seven times more than the total a) If the pump without any conversion, delta buck starts and other measures, the EPS capacity should be working simultaneously pump motor capacity;

2) If the pump has a variable frequency start, the EPS capacity of the pump motor while working with a total capacity of 1: 1;

3) If the delta voltage starting, the EPS has a capacity of more than at the same time four times the working pump total capacity;

4) If the pump has a soft start antihypertensive action is initiated, the EPS capacity of more than three times the work of the pump while the total capacity;

5) The pump can be a size smaller fire pumps, spray pumps for water pumps. If the size is large, it is recommended PYS \ B Series EPS;

6) When used with an EPS or a water pump with a prepared, placed at the end, in addition to a second power supply, but also has a dual role of each vote, without additionally each switch device.

 

Seven programs: the fan is connected to the wiring diagram

Description:

1) If the fan without any frequency, step-down start, the EPS capacity should be more than seven times the work while the total capacity of the fan motor;

2) If the blower motor variable frequency start, the EPS while the total capacity of the fan motor is working capacity of 1: 1;

3) If the fans have a star-delta reduced voltage start, while the EPS capacity should be more than four times the total capacity of the fan;

4) If the fans have a soft start antihypertensive action is initiated, the EPS capacity should be the total capacity for the fan to work three times;

5) the blower for a smaller size exhaust fan, into the fan, etc., if the specification is large, it is recommended PYS \ B Series EPS;
