Electrical Installation
The installation should meet all the regulations currently in force for installations in explosive
atmospheres, in particular the standards IEC/EN 60079-14 and IEC/EN 60079-17 (whichever editions are
in force) or in accordance with other national standards. OLCT 700 and OLCT 710 are certified for use in
ATEX zones 1 and 2, group IIB+H2, T4.
Proper electrical installation of the gas detector is critical for conformance to Electrical Codes and to avoid
damage due to water leakage. Refer to Figure 7 and Figure 8 for proper electrical installation.
Figure 7:
Typical Installation
NOTE:
The Oldham Warranty does not cover water damage resulting from water leaking into
the enclosure. However, since the electronics are 100% epoxy encapsulated, only the wire
terminations could get wet. Moisture could cause abnormal operation and possibly corrosion to
the terminal connections, but permanent damage to the detector would not be expected.
NOTE:
Unused port should be blocked with the M20x1.5 male plug supplied by Oldham
(ATEX and ‘Ex d IIC’ certified). The engagement shall be 5 threads at least.
Unused port shall be
sealed with the « Ex d »
certified plug delivered
along with the transmitter.
