6 DC output 0-10V
1 Phase indication
Phase indicator for PF1 and PF2 input with reference to PE. To guarantee correct phase angle synchronization,
the red lamp must illuminate. Otherwise the phase angle setting is 180 degree inverted.
2 EUT supply Input PF1, PF2, N, PE
Input plug for the EUT power supply (4mm safety banana plug). The input is not fused. The internal power fail
switches (PF1, PF2) protect the system against overcurrent and are configurable.
- PF1: Mains voltage to EUT phase L
- PF2: Reduced dip voltage to EUT phase L (used for dip voltages as per IEC 61000-4-11)
- N: Neutral to EUT supply
- PE: Protected earth to EUT supply
3 HV and COM output
The direct HV and COM outputs are floating output plugs for surge impulses.
The direct HV and COM output of the surge generator is located at the rear panel of the
generator. It is not allowed to connect these outputs to any other coupling/decoupling network
than manufactured by EM TEST. Before to connect any external networks to this output the
operator must contact the manufacturer. Any damages due to this matter are not covered by
warranty.
The direct pulse output shall also not be used to connect the generator directly to any power
Attention
conducting lines
The wave shape measured at the direct pulse output must not be within the tolerances specified in
IEC 61000-4-5. The pulse shape shall be verified at the CDN output directly, no matter whether it
is an internal or external CDN.
4 Ventilation
A power controlled ventilator is cooling the compact NX5 generator. During the most application the ventilator
runs with variable speed depends the cooling requirement.
After long term duration tests the generator 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)
