2-4. Connecting Mains and Load Cables
Installation and wiring must be performed in accordance with the local electric laws/regulations and execute the
following instructions by professional personnel.
Make sure the mains wire and breakers in the building are enough for the rated capacity of UPS to avoid the haz-
ards of electric shock or fire.
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.
Switch off the mains switch in the building before installation.
Turn off all the connected devices before connecting to the UPS.
2-4-1 Prepare input and output cables
Prepare the input and output cables as described in Table 5 on page 12 and as shown in the figure below.
The selections for color of wires should be followed by the local electrical laws and regulations.
Remove 5/8" length of insulation from each of the conductors and terminate each conductor with a ferrule.
2-4-2 Connect the input and output cables to the terminal
Remove the cover from the terminal block housing located on the rear panel of UPS. Then connect the wires as
shown in figure 13 on page 15 (Refer to Table 5 on page 12 and to Figure 11 on page 13). It is suggested that the
input and output cables to the UPS be housed in earthed, metal conduits suitable for the wire box cover opening
(1.375 inches).
After connecting the wires and strain relief reattach the cover to the terminal block housing.
NOTE: Make sure that the wires are connected tightly to the terminals. Refer to Table 5 on page 12.
