WARNING
AXG### and AXW### magnetic owmeter
(Integral Flowmeter and Remote Sensor), and
AXG4A and AXW4A Remote Transmitter are
products which have been certied as explosion
protection type products if model code for
explosion protection is specied. Strict limitations
are applied to the structures, installation
locations, external wiring work, maintenance and
repairs, etc. of these products. Sufcient care
must be taken, as any violation of the limitations
may cause dangerous situations.
Be sure to read this manual before handling the
explosion protection type products.
WARNING
The terminal box cover and display cover are
locked by hexagon socket head cap screw. In
the case of opening the cover, use the hexagonal
wrench (nominal size 3). Read the Maintenance
Manual, IM 01E22A01-02EN or IM 01E24A0102EN, for the procedure. Before opening
the cover, be sure to check that the power of
owmeter has been turned off. Once the cover is
closed, be sure to re-lock the product.
Be sure to lock the cover with the screw by using
the hexagonal wrench after tightening the cover.
IMPORTANT
For multiple approval types:
(Transmitter Wiring Terminal: Clamp type)
For the installation of this transmitter, once a
particular type of protection is selected, any
other type of protection cannot be used. Apply a
permanent mark in the check box of the selected
approval type on the certication label on the
transmitter to distinguish it from unused approval
types.

2.3 Installation
Read the Installation Manual, IM 01E22A01-01EN
(for AXG### and AXG4A) or IM 01E24A01-01EN
(for AXW### and AXW4A), for basic installation
procedure.
• All wiring shall comply with EN 60079-14, and
local electric codes and requirements.
• Unused apertures shall be closed with suitable
certied blanking elements.
(The plug attached is certied.)
• If the magnetic owmeter is mounted in an area
in the presence of combustible dust, it shall
be installed in such a way that the risk from
electrostatic discharges and propagating brush
discharges caused by rapid ow of dust is avoided.
• The sensor is not surrounded by pipe insulation
material.
• Cable glands, adapters and/or blanking elements
with a suitable IP rating shall be of Ex db IIC/Ex tb
IIIC or Ex eb IIC/Ex tb IIIC certied by ATEX and
shall be installed so as to maintain the specic
degree of protection (IP code) of the product.
• Take care the following warning marking
“POTENTIAL ELECTROSTATIC CHARGING
HAZARD”.
• In order to prevent the grounding conductor from
loosening, the conductor must be secured to the
terminal, tightening the screw with appropriate
torque. Care must be taken not to twist the conductor.
• For multiple types of protection for terminal
compartment, permanently mark the protection
type installed. Once the type is marked, it cannot
be changed.
• If the product is installed as the protection type Ex e,
terminate all the cable nish with crimp terminal of
a rod shape which of conductor length is 5 to 6 mm
and cross section is 0.8 to 2.5 mm2, and connect
them reliably.
• For the installation of multi protection type, tick the
box of the selected type of protection type on the
label in order to avoid confusion.
e.g. In the case of selecting “db”, not “eb”
