6.1 Installation Preparations
NO TICE
● If the EPO function is required, prepare the EPO switch and cable before
installation. The recommended cable size is 0.3 mm
2
.
● If the TN-C system is adopted, short-circuit the input N and PE, and connect
the input PE and N to terminals on the N bar. The recommended cable size is
240 mm
2
.
● If a backfeed protection card is configured:
●
If the UPS output power supply is used (currently supported only by the
1600 kVA UPS), prepare a shunt release (matching the rated voltage of the
UPS) and cable (0.5–1.3 mm
2
cable recommended; the actual cable size
must meet the requirements of the backfeed protection card, fuse terminal
block, and shunt release).
●
If a third-party power supply is used, the voltage is less than or equal to
240 V AC, and the current is less than 6 A, prepare a 6 A fuse, shunt
release, and cable (0.5–1.3 mm
2
cable recommended; the actual cable size
must meet the requirements of the backfeed protection card, fuse terminal
block, and shunt release).
● In a parallel system, the length and specifications of power cables on each UPS
should be the same to achieve current equalization in bypass mode. The power
cables include bypass input power cables and UPS output power cables.

●
Do not install the UPS in a high-temperature, low-temperature, or damp place
that is beyond the technical specifications.
