4.2 Input and Output Power Cords and Protective
Earth Ground Installation
1. Notes for installation
1)
The UPS must be installed in a location with good ventilation, far
away from water, inflammable gas and corrosive agents.
2)
Ensure the air vents on the front and rear of the UPS are not
blocked. Allow at least 0.5m of space on each side.
3)
Condensation to water drops may occur if the UPS is unpacked in a
very low temperature environment. In this case it is necessary to
wait until the UPS is fully dried inside out before proceeding
installation and use. Otherwise there are hazards of electric shock.
4)
Once the installation is completed, the side mounting brackets
（
used in shipping
）
shall be fixed back to ensure the stability of the
UPS enclosure. If impossible, additional stability can be added by
anchoring the mounting brackets to the floor with M8 bolts. See Fig.
4-5.

2. Installation
Installation and wiring must be performed in accordance with the
local electric code and the following instructions by professional
personnel.

For safety, please cut off the mains power switch before installation.
1) Open the terminal block cover located on the rear panel of the
UPS, please refer to the appearance diagram.
2) For tower 3/1 10K/10K-31C UPS, it is recommended to select the
UL1015 8AWG(10mm
2
) wire or other insulated wire which
complies with AWG Standard for the UPS input and output
wirings.
3) For tower 3/1 20K UPS, it is recommended to select the UL1015
6AWG(25mm
2
) wire or other insulated wire which complies with
AWG Standard for the UPS input and output wirings.
Note:
Do not use the wall receptacle as the input power source
for the UPS, as its rated current is less than the UPS’s
maximum input current. Otherwise the receptacle may be
burned and destroyed.
4) Connect the input and output wires to the corresponding input
and output terminals according to the following diagram.
Note:
you must make sure that the input and output wires and
the input and output terminals are connected tightly.
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 output breaker between the output terminal
and the load, and the breaker should with leakage current
protective function if necessary.
