6.2.10 Single-phase input/three-phase output connection
(only Archimod® 20kVA and 40kVA) Inverter in the 120° THREE-PHASE mode
To configure the UPS as a single-phase input/three-phase output with inverter in the 120° THREE-PHASE mode, 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.
Note: only the Archimod®20 and 40kVA models can be configured as 120° single-phase/three-phase.
ATTENTION
In this configuration with 120° THREE-PHASE inverter mode, the bypass cannot be used and terminals L1byp, L2byp
and L3byp of the bypass input disconnector must not be connected.
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 L1in-L1byp, L2in-L2byp and L3in-L3byp on the relative disconnectors; the
bypass line must not be used.
- Connect cable L1 of the mains input line to its terminal L1in on the mains input disconnector using a suitable cable
terminal.
ATTENTION
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.
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 on 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.
