models 80, 100 and 120kVA for connecting to the external
battery cabinets are on the bottom end of the copper bars at the bottom rear of the UPS, marked
with + and -.
ATTENTION: there are dangerous live parts inside the equipment due to the internal batteries
even if all the fuse holder disconnectors are opened. To remove the battery induced voltage,
remove at least 1 battery box from each battery shelf (which will interrupt the battery string
series).
5.2.5 Protections
To ensure correct operation of the UPS and its accessories the electrical system must be
adequately protected. Automatic differential switches and thermal circuit breakers are typically
used, connected between the mains supply and the UPS with the purpose of providing additional
protection in the event of overloads or short circuits.
INDICATION
Table 4, in the TABLES chapter, gives information about the thermal circuit breakers.
5.2.6 Earthing
Connect the earth wire leading from the low voltage switchboard panel to the EARTH terminal
on the UPS terminal block.
INDICATION
The wiring diagrams are given in the DIAGRAMS chapter.
5.2.7 Connecting the power supply
For safety reasons, connection of the power supply must be the last thing to be done.
Before connecting the power supply cables with input make sure that the maintenance by-pass
S1 is open in the OFF position and arrange fuses and jumpers on the terminal block according
to the required input-output configuration.
The type and cross section of the connecting cables must be chosen according to their operating
current and laying must be as established by existing laws.
In the TABLES chapter, tables 1 to 6 give indication about the sizing of cables, fuses, circuit
breakers and RCDs as well as an example of cable sizing if unipolar cables are used, without
a sheath, in PVC and laid in a pipe above ground.
MAINS INPUT CONNECTION:
Before connecting the mains input, check that the available mains power is higher or the same
as the UPS’s rated input power. Also check that the cables to connect to the UPS are discon-
nected upstream and there is no voltage.
• Connect the earth cable to its terminal on the base of the equipment.
• Connect the neutral mains input cable to its terminal on the mains input disconnector using a
suitable cable terminal.
• Connect cables L1, L2, L3 of the mains input line to their terminals on the mains input discon-
nector using suitable cable terminals and taking care to observe correct cyclicity of the phases
L1, L2 and L3.
