Safety notes
1. Use steute batteries of type Ex RF BAT 3.6 V with the EC type test
certificate BVS 18 ATEX E 035 X, IECEx BVS 18.0056X only.
2. Modifications of or repairing the battery are not allowed.
3. The above mentioned batteries are intrinsically safe and thus may
also be replaced within the hazardous area. When handling batter-
ies within the hazardous area, exercise due care. Avoid short-cir-
cuits or damage of the battery. In hazardous areas, transport the
batteries in suitable, electrically insulated packaging only.
4. The battery replacement must be exclusively carried out by author-
ised personnel. The authorised personnel must have knowledge
about protection methods, prescriptions for equipment for hazard-
ous area and its Ex marking.
5. Do not use visibly damaged batteries.
Keep away from hazardous areas.
6. Install and remove the battery manually only. Do not use any tools.
7. Observe the operating instructions of the batteries.
Mounting notes
Mounting notes for inductive Ex Wireless inductive sensors series
Ex RF IS M** nb-ST Xm. Ex Wireless inductive sensors Ex RF IS M**
nb-ST Xm are installed non-flush only. For the installation, observe the
following conditions, »Free field«, »Reciprocal influence«, »Tightening
torque«, and »Front surface«.
Free field
With Ex Wireless inductive sensors, the function principles are based
on the influence of a stray electromagnetic field. Because this stray
field does not only interfere with the object to be dectected , but also
with other conductive objects and also interferes with other Ex wire-
less inductive sensors, observe some mounting conditions. Opposite
the active surface, the minimum distance to/of a conductive surface
is 3 x s n .

Ex RF IS M** nb-ST Xm and distance to an opposite conductive
surface.
Reciprocal influence
If Ex Wireless inductive sensors Ex RF IS M** nb-ST Xm of the same
design are operated side by side, the oscillators for generating an
electromagnetic field may interact with each other. This effect is unde-
sirable and can lead to faulty operations. To avoid this effect, observe
the distances of the adjacent Ex Wireless inductive sensors as
shown below.
Tightening torque
The Ex Wireless inductive sensors Ex RF IS M** nb-ST Xm have only
low tightening torques.
For tightening torques, see section »Technical data«.
Front surface
The Ex Wireless inductive sensor Ex RF IS M** nb-ST Xm partly con-
sists of ferrite. It is very shock-sensitive. Never use its front surface
as an end stop.

Cleaning
d diameter
- Use a damp cloth to clean devices in explosive areas. This prevents
s n rated switching
electrostatic charge.
distance
- In case of damp cleaning: use water or mild, non-scratching,

non-chafing cleaners.
- Do not use aggressive cleaners or solvents.
Disposal
- Observe national, local and legal regulations concerning disposal.
Metal
- Recycle each material separately. Dispose of contained
batteries correctly.
- Avoid overlong storage of the batteries.
