3) Installation Requirements
The unit must only be installed by suitably qualified personnel
in accordance with the latest issues of the relevant standards:
EN60079-14 / IEC60079-14: Explosive atmospheres -
Electrical installations design, selection and erection
EN60079-10-1 / IEC60079-10-1: Explosive atmospheres -
Classification of areas. Explosive gas atmospheres
The installation of the unit must also be in accordance with
any local codes that may apply and should only be carried
out by a competent electrical engineer who has the
necessary training.
The equipment must not be installed with any obstruction to
the flanged flameproof joint any closer than permitted as per
EN/IEC60079-14, table 13.
4) Special Conditions of Use
The stainless steel button is not earthed and may generate
an ignition-capable level of electrostatic charges. It has a max
capacitance of 6.33pF according to EN/IEC60079-0, clause
7.5.
Equipment is permitted to be wall mounted only in vertical
position. The enclosure base is permitted in two mounting
positions, with the double entry lowermost or uppermost.
No repair to the Flamepaths is permitted
