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 units 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.
