which is supplied with the instrument, must be used. The length of the cable
should be three meters maximum and it should have a separable plug (with three
connectors, L+N+PE), without a locking device, to mate with a socket outlet in the
building. The cable and the plug must conform to an appropriate European or
national standard.
10–30 VDC Power Input
10–30 VDC powered portable instruments have a male Binder connector on their
rear panel. It accepts DC power as follows:
Pin 1: DC Return
Pin 2: Earth (Chassis)
Pin 3: Not connected
Pin 4: 10–30 Volts DC
Male Binder receptacle, rear panel of instrument
The user must make the necessary power wiring connections, using the female
Binder plug supplied with your system. User-supplied power cable can have an
outer diameter between 5 and 8 mm.
To disassemble the plug, squeeze the two clips located in the middle of the plug
(position “C” below). This reveals numbered wiring connections inside, to be
matched one-to-one with the diagram above.
