The connection of the electrical panel should be supplied by a grounded outlet.
Otherwise, the UPS and the load connected to the output will be left ungrounded. The grounding system
must be checked, and must be strengthen if required. Potential difference between ground and neutral
must be less than 3V AC.
Descriptions of the UPS input output cable connection terminals are shown in figure 2.1
Recommended input line cable and fuse ratings are given in the table below.

NOTES:
The neutral conductor should be sized for 1,5 times the output/bypass phase current. These
recommendations are for guideline purposes only and are superceded by local regulations
and codes of practice.
2.4.1 Safety Earth
The safety earth cable must be connected to the earth BUS BAR and bonded to each cabinets in the
system and also the earthing and neutral bonding arrangements must be in accordance with the local laws.
ATTENTION!!!
Failure to follow adequate earthing procedures can result in electric shock hazard to
personnel, or the risk of fire.
2.4.2 Cable connection procedure
WARNING!!! All connections of the UPS must be done by qualified service personnel
After positioning the UPS, the cables must be connected as described below:
1. Verify all switches and fuses in front of the UPS are at
“0”
position. (OFF)
2. Connect the 3 phase AC input coming from the mains distribution panel to the AC input terminals as
shown on the label. (Figure 2.1)
ATTENTION!!!: ENSURE CORRECT PHASE SEQUENCE.
If there is a phase sequence error, UPS doesn’t transfer the load to INVERTER output. If
you can’t see SYNC:OK in the INFORMATION MENU on LCD, then change the input
phase sequence.
3. Connect the output of the UPS to the load distribution panel.
4. Connect the battery groups. Refer to battery installation section.
WARNING :
-
CHECK BOTH OF THE BATTERY GROUPS FOR CORRECT POLARITY AND VOLTAGE
-
DO NOT TURN ON THE BATTERY SWITCH (F5) BEFORE STARTING THE UPS
5. Connect the copper earth bus, to the safety earth of the mains distribution panel.
NOTE :
The earth and the neutral connections must be in accordance with the local rules.
WARNING: Note that the Input Neutral (N1) MUST also be connected to K10 terminal
