the relevant design specifications of the manufacturer. Repair work according to the values of Table 2
of standard EN 60079-1:2004 is not authorized.
If the encoder is used for operation in another temperature range than the range indicated in the EC
type examination certificate, an electrical/thermal test and a heating check must be performed at
selected critical locations. The manufacturer is to be informed about this.
– The cable gland is screwed on the cover with the M16 x 1.5 thread.
– The cover is fastened on the flange with 4 cylindrical head screws M4 x 0.7, strength class 8.8.
