➨
The VACUUBRAND controllers VNC 2 (E) and VNC 2 VARIO E can only be operated with compo-
nents compatible to the VACUUBRAND
VACUU•BUS system, see accessories.
VNC 2 VARIO E
The power for the VNC 2 VARIO E is supplied via the VACUU•BUS connection (24V DC) by the inte-
grated power pack of the NT VARIO pumps and pumping units.
The on/off switch at the front side of the controller separates only the IEC socket (connection mains ca-
ble) from the IEC plug (connection NT VARIO pump). Therefore a connected VACUUBRAND NT VARIO
pump or pumping unit can be operated and switched on and off via the VNC 2 VARIO E.
Permitted voltage and current at the IEC plug: See rating plate of the NT VARIO pump or pumping
unit.
