SPECIFIC CONDITIONS FOR SAFE USE (X):
1 The intrinsically safe circuits do not withstand the 500V AC test as specified in
IEC 60079-11 clause 6.4.13.
2 The antennas for type 5400, are non-conducting and the area of the non-conducting parts exceeds the
maximum permissible areas for Group IIC and according to EN/ IEC 60079-0: .2012/2011 clause 7.4:
20 cm
