Rear side coupling NX5 bs-3-480-16 / 32

1 Reference earth connection (Screw M4)
2 EUT power L1 & dc+, L2, L3, N & dc-, PE
3 Input HV & COM from NX generator
4 Ventilator
1
Reference earth connection
The generator has to be connected to the reference earth plane of the test set up. The connection at the rear
part of the generator is an alternative to the grounding point at the front panel
2
EUT supply Input L1, L2, L3, N, PE
Input plug for the EUT power supply (4mm safety banana plug up to 32A). The input is not fused.
- L1, L2, L3: Mains voltage to EUT phase L1 to L3
- N:
Neutral to EUT supply
- PE:
Protected earth to EUT supply
3
HV and COM output
The direct HV and COM input for surge impulses.
4
Ventilation
A power controlled ventilator is cooling the coupling NX5. During the most application the ventilator runs with
variable speed depends the cooling requirement.
After long term duration tests the coupling NX should keep on running for some minutes to cool down the
system.
5
Power on switch
The switch is part of the mains filter. Mains fuses are part of the filter. (230V / 2A and 115V / 4A)
6
Mains Input and Fuse
Mains input for the generator power supply.
85 V – 254 V ac
Input voltage:
Fuses:
115 V:
230 V:
7
Sys Link input
Sys link is the internal control bus to the connected compact NX devices. The sys link is a daisy chain wired bus
for connect the devices in series. The bus includes a 26 pole high density connectors.
