Mains input connection:
Before starting to connect 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 disconnected upstream and there is no voltage.
- Check that the earth cable leading from the low voltage distribution panel is connected to the 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.
- Remove the cables jumpering terminals L2in-L2byp and L3in-L3byp on the relative disconnectors - insert 1 copper
plate on terminals L1byp, L2byp and L3byp making sure the cable, jumpering terminals L1in and L1byp on the relative
disconnectors, is in place and tightened correctly (if a separate bypass line is not used leave this cable where it is).
- Connect cable L1 of the mains input line to its terminal L1in on the mains input disconnector using a suitable cable
terminal.
ATTENTION
The plate must be mounted in contact on the disconnector switch terminals with the cable terminals on top – and
not vice versa.
The equipment’s neutral passes through.
The neutral conductor cable of the mains input must ALWAYS be connected!
If the neutral is not connected the UPS could be seriously damaged when powered off the mains.
In the three-phase output configuration the UPS can be seriously damaged if there is one or more EC15 connectors
on the UPS’ backplane boards.
If this is the case, remove all the EC15 connectors.
Separate bypass line connection (if any):
The connection of a separate bypass line is only possible if the neutral conductor of the bypass line and that of the mains
input are in common (the same potential). The neutral of the UPS’s mains input, bypass input and through output are
connected together internally.
Before connecting the bypass line, 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 disconnected upstream and there is no voltage.
- Connect the earth cable to its terminal on the base of the equipment.
- Remove the cable jumpering terminals L1in and L1byp on the relative disconnectors.
- Connect the Neutral bypass line cable to its terminal on the bypass input disconnector using a suitable cable terminal.
- Connect cable L1 of the bypass input line to its terminal L1byp of the bypass input disconnector using suitable cable
terminals and checking that the copper plate is in place between terminals L1byp, L2byp and L3byp.
ATTENTION
The plate must be mounted in contact on the disconnector switch terminals with the cable terminals on top – and
not vice versa.
The neutral conductor cable of the separate bypass line must ALWAYS be connected!
If the neutral is not connected the UPS could be seriously damaged when powered off the mains.
Output connection:
Before connecting the output make certain the UPS is off and there is no voltage on the output disconnector terminals.
- Connect the output line earth cable to the terminal on the base of the equipment.
- Connect the output line Neutral cable to its terminal on the output disconnector using a suitable cable terminal.
- Connect cables L1,L2, L3 one by one of the output line to their terminals L1out, L2out and L3out of the output
disconnector using suitable cable terminals and taking care to observe correct cyclicity of the phases L1, L2 and L3.
ATTENTION
When connecting the output line take great care not to reverse the UPS cables that are already on the terminals of
the disconnector switch.
