Connection and commissioning
3.1 General
When selecting the cable, make sure that the permitted maximal values are taken
into account according to the EC type examination certificate.
The electrical Ex network must be realized with its own cable. Only a shielded
cable may be used for the installation of the encoder; we recommend the cable
LIYCY 2 x 0.75 mm

, sheath color blue.
The cable screen is connected on both sides. The shield is grounded on the non-
hazardous supply side. At the other end of the cable, the shield is connected on
the insulated metal housing of ENCO 08. The housing of ENCO 08 may also be
earthed in potentially hazardous area, observing the regulations according to DIN
EN 60079-14. The meter housings of turbine gas meters and rotary displacement
meters as well as the aluminum housing of the ENCO 08-M must be earthed.
A stable installation of the intrinsically safe cables is absolutely necessary. The
connection cables must be equipped with wire end ferrules.
