Operating Procedure For Connecting The Long Backup Time Model Ups With The External Battery - Phasak PH 9701 Manual De Uso

12.2.2. Installation (cont.)
5. The protective earth ground wire refers to the wire connection between the equipment which consumes
electric equipment and the ground wire. The wire diameter of protective earth ground wire should be at least as
above mentioned for each model and green wire or green wire with yellow ribbon wire is used.
6. After having completed the installation, make sure the wiring is correct.
7. Please install the leak current protective breaker at the output power distribution panel of the UPS if
necessary.
8. To connect the load with the UPS, please turn off all the loads first, then perform the connection and finally
turn on the loads one by one.
9. No matter the UPS is connected to the utility power or not, the output of the UPS may have electricity. The
parts inside the unit may still have hazardous voltage after turning off the UPS. To make the UPS have no output,
power off the UPS, and then disconnect the utility power supply.
10. Suggest charging the batteries for 8 hours before use. After connection, turn the input breaker in the "ON"
position, the UPS will charge the batteries automatically. You can also use the UPS immediately without charging
the batteries first, but the backup time may be less than the standard value.
11. If it is necessary to connect the inductance load such as a monitor or a laser printer to the UPS, the start-up
power should be used for calculating the capacity of the UPS, as its start-up power consumption is too big when
it is started.
Important notes: If the UPS is used in single mode, JPI and JP2 must be connected by 10AWG(6mm2). If the
UPS is used in parallel mode, the Jumper between JP1 and JP2 must be removed.

12.3. Operating procedure for connecting the long backup time model UPS with the external battery.

12.3.1. The nominal DC voltage of external battery pack is 240VDC. Each battery pack consists of 20 pieces of 12V
maintenance free batteries in series. To achieve longer backup time, it is possible to connect multi-battery packs, but the
principle of "same voltage, same type" should be strictly followed.
12.3.2. The connector of the external battery cable is used to plug into the external battery socket of the UPS, the other
end of the external battery cable is made of three open wires with ring terminals to connect with the external battery
pack(s). The procedure of installing battery bank should be complied with strictly. Otherwise you may encounter the
hazardous of electric shock.
1. A DC breaker must be connected between the battery pack and the UPS. The capacity of breaker must be not
less than the data specified in the general specification.
2. Set the battery pack breaker in "OFF" position and connect the 20 pieces of batteries in series.
3. You must connect the external battery cable to the battery first, if you connect the cable to the UPS first, you
may encounter the hazardous of electric shock. The positive pole of the battery is connected to the 10KS in
parallel with blue andbrown wires; the negative pole of the battery is connected to the 10KS in parallel with black
and white wires; the green and yellow ribbon wire is connected to the ground of the battery cabinet.
12.3.3. To complete the connection by plugging the connector of the external battery cable into the external battery socket
of the UPS. Do not attempt to connect any loads to the UPS now. You should connect the input power wire to the right
position first. And then set the breaker of the battery pack in the ON position. After that set the input breaker in the ON
position. The UPS begins to charge the battery packs at the time.
