24 General Information
1.6.3 Electrical Connections
Notice The local regulations for electrical connections must always be observed
(in Germany VDE 0100). The mains voltage rating for the Protec P3000
can be read off from the name plate left of the power switch. The mains
voltage setting of the Protec P3000 is fixed and can not be changed. A
separate fuse for each of the mains conductors has been integrated into
the mains socket (Fig. 9/6).
The mains voltage is applied to the Protec P3000 via the detachable mains cable
which is supplied with the leak detector. A main power socket is available for this
purpose at the rear of the main unit.
1.6.4 RS232 Interface
The Protec P3000 is equipped with a RS232 interface which is located on the rear
right side of the main unit. This interface is of the DCE type (Data Communications
Equipment) and allows the connection of a PC for monitoring and data logging. The
connection is provided through a commercially available Sub-D plug. For further
information see “Interface Description Protec P3000” (kins26e1).

Before connecting the Protec P3000 to the mains you must make sure that
the mains voltage rating of the Protec P3000 coincides with the locally
available mains voltage.
Only 3-core mains cables having a protective ground conductor must be
used. Operation of the Protec P3000 with the ground conductor unconnected
is not permissible.
