1. Safety rules
Increased safety enclosures type ZENITH P are designed as Group II
Category 2 Equipment and is suitable for use for fixed installation in areas
with explosion hazard designated Zone 1 or Zone 2 to EN 60079-0, or
Zones 21 or Zone 22 to EN 61241-0.
These operating instructions must be kept in safe place for later
consultation. During operation, do not leave this instruction manual or
other objects in the enclosure.
Operate the enclosures type ZENITH P only for their intended duty in the
undamaged and clean condition, and only where the resistance of the
material to the surroundings is assured. The enclosures are designed to
withstand an impact of 7 J, and to be used in normal conditions of
vibration. They are not designed for use in areas subject to intentional
or extreme conditions of vibration.Enclosures are made of carbon loaded
glass reinforced polyester. The enclosures have a surface resistance
between 106 and 109 Ω. They do not present a hazard from static
electricity. In the event of incorrect assembly, the type of protection will
no longer be assured.

The ambient temperature is marked on the label.
The equipment is certified in ambient temperature in the range –60°C
+75°C (for enclosures 644.0380 and 644.0390 -60°C +60°C) and should
not be used outside these ranges.
The user must submit the complete unit for EC-Type examination
by a Notified Body if it is to be used in a hazardous area.The
Installation, Operation and Maintenance Instructions must be always
included with the certified electrical apparatus.
4. Installation

in accordance with the applicable code of practice (e.g. EN
60079-14 and EN 61241-14) and the provisions of the national safety
and accident prevention regulations and this instruction manual.
4.1 Conditions of Safe Use
The IP rating of the enclosure shall be maintained for the area of
installation by the use of correct arrangement of cable & gland & sealing
and in accordance with the installation rules as detailed in EN 60079-14.
Where other certified components are part of the assembly, the user
must take account of any limitation listed on relevant certificates.
Where enclosures are to be drilled use equipment that is suitable for the
material of the enclosure (GRP polyester) and ensure that the correct
drilling speeds / feed rates are used. The holes must be cut inside the
approved drilling areas for each wall, and must be done with absolute
quality and without burrs.
Tapping of standard 4 mm thick wall is possible.
These instructions assume that the required cable entries have been pre-
drilled (and may be threaded) on the enclosure. The cable glands are
usually fitted during installation.
The enclosure must be installed in absence of damage and free of defects.
4.2 Accessories
