4 Electrical Installation
This chapter mainly introduces the electrical installation of the UPS, including the power cable and signal cable connecting
procedures and methods.
After completing the mechanical installation of the UPS, it is necessary to connect the power cable and signal cable of the
UPS. All the signal cables, whether shielded or not, shall be kept away from the power cables.

4.1 Wiring of Power Cable
4.1.1 System Configuration
The cable size of the system power cable shall meet the following requirements:
UPS input cable
The cable size of the UPS input cable differs with the UPS power ratings and input AC voltages, provided that it meets the
requirement of maximum input current, including the maximum battery charge current, see Table 4.1 on the next page.
UPS bypass and output cable
The cable size of the UPS bypass and output cable differs with the UPS power rating and output AC voltages, provided that
it meets the requirement of nominal output or bypass current, as shown in Table 4.1 on the next page.
Battery cable
Each UPS connects to its battery through the three cables connecting to the positive pole, negative pole and neutral line.
The cable size of the battery cable differs with the UPS power ratings, provided that it meets the battery discharge current
requirement when the battery discharges to near EOD voltage, as shown in Table 4.1 on the next page.
4.1.2 Maximum Steady State AC and DC Currents
The power cable must be selected according to the current and voltage values in Table 4.1 on the next page as well as the
local wiring regulations, and take environmental conditions (temperature and physical media) into consideration, then refer
to Table 3B in IEC 60950-1.
