Hazardous marking explanation

These vacuum cleaners are certified by an NRTL to operate in
a ClassII Div2 area where dusts belonging to Group F, G are
present. These are marked as follows:
Ibs.
ClassII Div2: is an hazardous area
(kg)
(1) In which combustible dust due to abnormal operations
may be present in the air in quantities sufficient to produce
198
explosive or ignitable mixtures; or
(90)
(2) Where combustible dust accumulations are present but
are normally insufficient to interfere with the normal operation
of electrical equipment or other apparatus, but could as a
result of infrequent malfunctioning of handling or processing
Ibs.
(kg) equipment become suspended in the air, or
(3) In which combustible dust accumulation on, in or in
the vicinity of the electrical equipment could be sufficient
211.6
(96)
to interfere with the safe dissipation of heat from electrical
equipment or could be ignitable by abnormal operation or
failure of electrical equipment.
Ibs.
Group F, G: Atmospheres containing but not limited to:
(kg)
carbon, black coal, coke dust, flour starch or grain dust.
T4A: the maximum surface temperature measured on the
284.4
vacuum cleaner at the maximum ambient temperature is 120°C.

WARNING!
312
■ Make sure there is no evident sign of damage to
(142)
the vacuum cleaner before starting work.
■ Before plugging the vacuum cleaner into the
electrical mains, make sure the voltage rating
Ibs.
indicated on the data plate corresponds to that of
(kg)
the electrical mains.
■ Plug the vacuum cleaner into a socket with a
313
correctly installed ground contact/connection.
(142)
Make sure that the vacuum cleaner is turned off.
■ The plugs and connectors of the connection cables
must be protected against splashes of water.
Ibs.
■ Check that for proper connection to the electrical
(kg)
mains.
■ Use the vacuum cleaners only when the cables
313
that connect to the electrical mains are in perfect
(142)
condition (damaged cables could lead to electric
shocks!).
■ Regularly check there are no signs of damage,
excessive wear, cracks or aging on the electric
cable.
WARNING!
When the vacuum cleaner is operating, do not:
■ Crush, pull, damage or tread on the cable that
connects to the electrical mains.
■ Only disconnect the cable from the electrical mains
by removing the plug (do not pull the cable).
■ Only replace the electric power cable with one of
the same type as the original: S00W. The same rule
applies if an extension is used.
■ The cable must be replaced by the manufacturer's
Service Center staff or by equivalent qualified
personnel.

Warning labels

Figure 3
Labels:
1. Warning: To reduce the risk of electric shock - do not use
outdoor or on wet surfaces
Caution: Open circuit before removing cover and keep
covers tight while circuits are live
Warning: Explosion hazard - use only Nilfisk hose
Warning: The vacuum must be cleaned only with a damp
cloth
2. Emptying: If this vacuum cleaner is used to collect
hazardous material, do not attempt to open its contents
without personal protective clothing and respiratory
protection.

Extensions

If an extension cable is used, make sure it is suitable for the
power input and protection degree of the vacuum cleaner and
for hazardous area ClassII Div2 group F and G.
WARNING!
The vacuum cleaner's power socket must be protected
by a differential circuit-breaker with surge current
limitation, that shuts off the power supply when the
current discharged to the ground exceeds 30 mA for
30 ms or an equivalent protection circuit.
WARNING!
Never spray water on the vacuum cleaner: this could
be dangerous for persons exposed and could short
circuit the power supply.
WARNING!
Comply with the safety regulations governing the
materials for which the vacuum cleaner is used.

Dry applications

[ NOTE ]
The supplied filters and the dust bag (if applicable) must be
installed correctly.
WARNING!
Comply with the safety regulations governing the
materials for which the vacuum cleaner is used.
