Data for connection on all Ex e terminals:
stripping lenght for wires: 8 mm, torque for screws: 0.6 - 0.8 Nm.
The exact I/O-configuration for circuits A, B, C and D is order-specific and can be determined by
the CG number shown on the converter. Therefore check the data on the back of electronics unit
of the signal converter. The CG number contains 10 characters of which the last three characters
(XYZ) determine the configuration of the I/O circuits:
The wiring of instruments has to be in accordance with the requirements as specified in the
relevant national or international standard for electrical installations in hazardous areas, e.g.
