The equipment should be switched off during installa-
tion and interconnection.
Because of the capacitors in the internal coupler of NSG
3040, earth leakage currents of up to 4 A can occur in
the EUT power supply network. The test system must
therefore be correctly earthed and be powered from a
supply that is not protected by a residual current detec-
tor (RCD).
Plug X1: NSG 3040 system interface IN – to be connected to NSG 3040 or to
another accessory, to X2 plug.
