P1.3
Sample gas pumps of type P1.3 (12 V DC/24 V DC) and P1.3E (all
voltages) are delivered as standard with a 3 m connecting
cable.
It is essential to connect the protective earth conductor to
the marked protection earth terminal. At model P1.3E
(115 V/230 V) the protective earth has to be connected to the
green/yellow wire of the connection cable (see Fig. Electrical
connection P1.3 pumps).
