10 Connection for equipotential bonding
1) Option
2) The connection of the pressure sensor (see page 24) must not be
connected to the sample gas feed path when measuring flammable
gases.
Design of the gas connections: Internal flame barriers of rust- and acid-
resistant steel 1.4571 with 1/8 NPT female thread
Connecting cable: The non-detachable connecting cables for data
transmission and the 24 V DC supply are an integral component of the
flameproof case of the analyzer unit. In each case, they are 10 m long
and may not be shortened to a length of less than 1 m.
NOTE
The extra space required below the analyzer unit for the connecting
cables (approx. 10 cm) and above the analyzer unit for opening the case
(approx. 40 cm) must be considered.
