2.4 Residual risks
2.4.1 Risk of an explosion caused by electrical ignition sources
Electrical ignition sources can trigger fires and explosions in a potentially explosive atmosphere.
Non-approved components
Specific hand-held scanners and accessories (including universal supply module, battery, cable) are
suitable for each potentially explosive atmosphere. Hand-held scanners and components that have not
been approved for the respective potentially explosive atmosphere may trigger explosions.
Only use components that have been approved for the relevant potentially explosive atmosphere.
Spark formation during battery change and cable connection
Sparks can arise when changing the battery or connecting cables. Sparks can trigger an explosion in
a potentially explosive atmosphere.
Only insert or remove the battery outside the potentially explosive atmosphere.
Only connect or disconnect the cable outside the potentially explosive atmosphere.
Always have cables connected by a qualified electrician.
Spark formation caused by the battery falling out / the connection cable coming unplugged
The following risks arise if the safety lock on the underside of the hand-held scanner is not correctly
closed:
‒ The battery on a Bluetooth hand-held scanner can fall out.
‒ The connection cable on a corded hand-held scanner can come unplugged.
This can produce sparks which can trigger an explosion.
Check that the safety lock is correctly closed before taking the hand-held scanner into the
potentially explosive atmosphere.
Broken enclosure: loss of explosion protection
The hand-held scanner has been tested for falls from a height of up to 2.4 m (7.9 ft) (Zone 2 / Div. 2)
and 1.2 m (4 ft) (Zone 1 / Div. 1). There is a risk of the enclosure breaking during falls from a greater
height, in which case the explosion protection is no longer guaranteed.
Protect hand-held scanners from falling from a greater height.
If the hand-held scanner has fallen from a greater height or you suspect a damaged enclosure:
– Remove the hand-held scanner from the potentially explosive atmosphere immediately.
– Send the faulty hand-held scanner to BARTEC and reference the RMA number you were
issued.
Corrosion: loss of explosion protection
The enclosure of the hand-held scanner has protection class IP65, however constant exposure to
moisture can lead to corrosion. This may lead to the loss of the explosion protection.
Protect hand-held scanners against constant exposure to moisture.
Do not subject hand-held scanners to any damp weather conditions.
