7. Measure the battery string voltage. If the voltage is correct, resume the battery baffle plate to its original place, and
tighten the fixing screws to baffle the battery string.
8. Put the battery protection cover back.
2.4.4 Connecting Cables
Note
1. Use sheathed cables for AC cables, DC cables, and communication cables in and out of each cabinet. Besides, separate these
cables.
2. Open all switches and fuses before electrical connection.
3. Only qualified personnel are permitted to connect the mains power cables.
4. Stay away and do not bridge a system that has hazardous energy over 240VA.
5. Connect the power system with other equipment only if the 60950-1 relevant standard is met.
6. The AC thermal control MCB and DC thermal control MCB in the power cabinet supply power to the thermal control device
and socket in each cabinet, when the system is running, make sure that the thermal control MCBs are closed.
7. Distribute cables by referring to the wiring diagram. Make sure that the cable connection is correct before powering on the
system.
Parallel Cable Connection
Relevant cables have been connected and the cabinet has been tested before delivery. If the cabinets need to be
paralleled for use, then you should connect the cable between cabinets onsite. This manual takes three single
cabinets parallelizing for example to describe the cable connection between cabinets. There is a white 6 Pin terminal
installed on the right side wall of each cabinet, which feeds power to the socket and thermal control device of the
cabinet, as shown in Figure 2-18 Take the typical configuration (battery c power c equipment cabinet)
for example, when paralleling the cabinets, you should connect the power cable of the thermal control device from
battery cabinet to the power cabinet, and the cables of each sensor to FSU in the power cabinet. Moreover, the
power cables of the thermal control device from the equipment cabinet to the power cabinet, the AC socket power
cable, and the cables of each sensor to FSU in the power cabinet need to be connected (such as the micro switch,
temperature & humidity sensor, infrared sensor are optional parts, if selected, you should connect the corresponding
cables).
Among which, the cross-cabinet cable used by thermal control device is optional, if selected, you should connect one
end of the tube terminal of the cross-cabinet cable for DC power use to the 6 Pin terminal, and the other end to the 3
Pin terminal led out from the DC output MCB on the power subrack in the power cabinet according to the cable marks
and the wiring diagram. In the same way, connect one end of the cross-cabinet cable for AC power use to the 6 Pin
terminal, and the other end to the AC output MCB used by thermal control device and AC socket on the power
subrack in the power cabinet according to cable marks and the wiring diagram (Note: make sure that the L is
connected to the AC output MCB, and N to the neutral line terminal). If the cross-cabinet cable of Vertiv is not
selected, then you should connect the cross-cabinet cable by yourself according to above method. All the sensors are
optional, and the corresponding cables are not connected for standard cabinet, the onsite engineering personnel shall
carry out the cable connection according to actual requirement.
