6.2.9 Single-phase input/single-phase output connection (only Archimod® 20kVA and 40kVA)
To configure the UPS as a single-phase input/single-phase output follow the instructions given below.
Before starting to connect, make sure that the mains input, maintenance bypass and output disconnector switches on the
front panel of the UPS are open in the OFF position.
ATTENTION
Only the Archimod® 20 and 40kVA models can be configured as single-phase/single-phase.
Follow the instructions in paragraph 2.4 to select the right output configuration on the operator panel before
starting the UPS.
When connecting the input, bypass (if used) and output cables take care not to reverse the UPS cables that are
already on the terminals of the relative disconnector switch.
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 between terminals L1in, L2in and L3in of the output disconnector.
- 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.
Separate bypass mains 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.
- If there is a separate bypass line earth cable connect it to the 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.
