Electrical information connecting with earth and emergency stop

Do not loosen or unscrew the breather valve in a potentially explosive
atmosphere.
CAUTION
A vent line does not need to be connected to the breather valve as no gas escapes
in normal operation.
ATTENTION
If a vent line is connected, it must be routed into a safe ventilation area as
specified below and must be protected from dirt and rain
The following specifications apply to a vent line (please contact your TAC if you are in
any doubt):
The additional pressure drop caused by the pipeline depends on fittings, bends
•
and the material used. It must not allow the pressure inside the housing to rise
above 100 mbar (10 kPa). If a straight smooth pipe is used with a minimum
internal diameter of 8 mm and an inlet pressure of up to 3 bar, lengths of
around 40 m are possible. If you would like to use smaller diameters and
lengths of over 40 m, please contact your TAC.
Completely separate pipeline, connection using the breather valve's internal
•
thread.
DO NOT CONNECT THE BREATHER VALVE'S PIPELINE TO OTHER
PIPELINES.
CAUTION
Reference is made to the appropriate technical regulations regarding the installation,
commissioning, decommissioning and maintenance work in general. All national, local
or company standards and regulations which apply at the installation site of the device
must always be given due consideration and applied. For example, Directive 99/92/EC
(ATEX 137) governs the installation and operation of electrical systems in potentially
explosive atmospheres. Do not fail to comply with this Directive in territories in which it
applies.
Honeywell cannot accept any responsibility for compliance with provisions and
regulations unless the work was carried out by Honeywell. We recommend that you read
through the appropriate regulations again before installation.
Compliance with standards and directives on the following topics, in particular, is
mandatory:
