2.6.1.3 Electrical connection
The power supply to monitoring head CST-Ex is an intrinsically safe, ungrounded passive
N-terminal output from XSK of the FC01-Ex via Stahl safety barriers, EG-Type test certificate
no. PTB 01 ATEX 2053.
Connection is by means of a light-blue LiYCY cable, 4 x 2 x 0.75 mm
2
, variable in length.
● Lay signal cable (shielded, blue) to DIN EN 60079-14, para. 12.2.2.3 (see also para. 2.5).
● Install equipotential bonding along the complete cable run of the intrinsically safe circuit
