Installation instructions

The installation, commissioning, maintenance and repair of
devices in potentially explosive atmospheres must only be
carried out by appropriately trained personnel. Works may be
carried out only by persons, whose training has included
instructions on different types of protection and installation
techniques, concerned rules and regulations as well as general
principles of zoning. The person must possess the appropriate
competences for the type of work to be conducted.
When operating with combustible dusts, comply with
EN 60079-31.
The safety instructions for electrical apparatus in potentially
explosive areas must be in accordance with Directive
2014/34/EC (ATEX) and IEC60079-14 (Installation of electrical
equipment in potentially explosive areas).
Comply with the applicable regulations for the protection of
employees to ensure safe operation.

2.3.1 Information about opening and closing the housing
DANGER
Risk of explosion if the device is operated with the
housing or terminal box open!
Before opening the housing or the terminal box, note the
following points:
— Check that a valid fire permit is available.
— Make sure that there is no explosion hazard.
— Switch off the power supply and wait for t > 4 minutes
before opening.
NOTICE
Adverse effect on the type of protection!
Damage to the cover thread results in loss of the "flameproof
(enclosure) (Ex d)" type of protection.
Handle the cover with care.
2.3.2

Requirements for operation with the "flameproof

(enclosure)" (Ex d) type of protection

Prior to mounting, check to ensure that the I/P signal
converter meets the measurement and safety requirements
that apply at the measuring point.
— When making the electrical connections, the parameters in
the specifications and the information in the explosion
protection certificate must be complied with.
— The device may only be operated with instrument air that
is free of oil, water, and dust. Flammable gases, oxygen or
oxygen-enriched gases must not be used.
2.3.3

Cable entries

When operating with the "flameproof (enclosure) (Ex d)" type
of protection, use only cable glands with the corresponding full
"Ex d" approval.
— Secure all cable entries against twisting and loosening by
using a medium-strength securing adhesive.
— When operating the I/P signal converter at an ambient
temperature above 60 °C (140 °F) or below -20 °C (-4 °F),
ensure that the cable entries and cables used are suited
to an operating temperature of up to the maximum
ambient temperature plus 10 K, or to an operating
temperature down to the minimum ambient temperature.

Operating instructions

2.4.1

Changing the type of protection

The devices can be operated as delivered with either the
"intrinsically safe (Ex ia)" or "flameproof (enclosure) (Ex d)"
types of protection.
A device that has been operated with the "flameproof
(enclosure) (Ex d)" type of protection must no longer be
operated with the "intrinsically safe (Ex ia)" type of protection,
as the electronics may have been damaged.
For this reason the devices must be permanently marked
during commissioning (e.g. cross out or mask over "Ex ia").
