5) automatic instant switching, can be unattended.
6) No noise, no pollution, pollution-free, flame retardant wires and devices and non-flame retardant properties.
Six, the installation forms
EPS floor type (standard distribution cabinet)
Seven, PYS / B Series design schematics
Option One: single inverter single load diagram
Description: When the three-phase input power is normal to provide a rectified DC inverter, charger while charging the battery pack; if the three-phase input power outage or below 380V - 15% time, KMI pull from the battery pack to the inverter provides DC. When you need to work the motor load, give the start signal (such as running signal, remote control, fire linkage signal), the inverter output immediately. From 0Hz - 50Hz frequency inverter power to the motor started, when its frequency reaches 50Hz keep running. Manual / automatic selection switch in automatic position for remote control and fire linkage (DC24V) operations can be carried out manually position the unit's operation, then the remote control and fire control linkage can not operate, signal and manual / automatic position, fire center monitoring.
Option Two: single inverter single load with a preparation of schematics and wiring diagrams
Description: single inverter single load with a preparation of schematics and wiring diagrams with a single inverter single load schematics and wiring diagrams are basically the same, just more of a standby switch control, automatic achieved by DC contactors KM1 or KM2 one can use a backup.
Note: use PYS / B Series EPS when a device control box within the EPS, one with no external control box.
Option Three: Dual Inverter single load with a preparation of schematics and wiring diagrams
Description: When the fire service requirements with a preparation time, can also be used in the form of double inverter, EPS addition of an inverter and a standby switch on the basis of a single inverter single load on the schematic, can achieve double insurance with a prepared function, other principles described with a single inverter single load with a spare schematics and wiring diagrams consistent.
Note: use PYS / B Series EPS when a device control one within the EPS, with no external control box.
Option 4: single inverter single application load wiring diagram
Description:
1) Load for fans, pumps and other fire-fighting facilities, or a load;
2) the capacity of the load capacity and EPS of 1: 1, do not require margin, and without increasing the buck starts, because this is already EPS inverter start function;
3) Start signal control startup and operation of the load is also subject to the EPS is connected;
4) EPS output must be directly connected to the motor load, the load should be removed without the original control cabinet, the original function of the control cabinet has been in the EPS;
5) load should normally be a single motor, but also need to be more than one, when more than one at the same time must also start or stop the run.
Eight, PYS-B series wiring scheme diagram (are configured within the dotted line in the EPS, EPS device settings were PE terminal strip or terminal).
Option One: Single Inverter with a prepared application wiring diagram
Wiring: persistent, fire linkage type
Description:
1) Load for fans, pumps and so on;
2) single load capacity of 1: 1, do not require margin, and no additional measures to start, because this frequency EPS already started;
Start signal control up and running 3) connected to the load by the EPS;
4) the load on the 1st and the 2nd machine automatically switches;
5) EPS output must be directly connected to the motor load, the load should be removed without the original control cabinet, the original function of the control cabinet has been in the EPS;
6) When the load is recommended by a need to prepare two dual inverter type.
Option Two: Dual Inverter two applications with a prepared wiring diagram
Wiring: persistent, fire linkage type
Description:
1) Load for fans, pumps and so on;
2) single load capacity of 1: 1, do not require margin, and no additional measures to start, because this is already EPS inverter start function;
Start signal control up and running 3) connected to the load by the EPS;
4) Load the No. 1 Unit 2 Unit 3 automatic switching;
5) EPS output must be directly connected to the motor load, the load should be removed without the original control cabinet, the original function of the control cabinet has been in the EPS;
6) For pumps with a preparation may also be dual-use applications inverter ways, but more than the cost of a single inverter is higher by about 50%.
Option Three: Mixed Wiring Applications Figure (1)
Wiring: persistent, fire linkage type
Description: The high-rise building fire pumps, because of greater power, use PYS / B Series EPS products, and other small power facilities chosen PYS series of EPS products to reduce costs, save water pump control measures and buck starts.
Option 4: Mixed wiring diagram application (2)
Wiring: persistent, fire linkage type
Description: The high-rise building fire pumps, spray pumps, because of its power, the choice of PYS / B Series EPS products, and other small power facilities chosen PYS series of EPS products to reduce costs, save water pump control and buck starts measures.
