Risk of an explosion caused by electrical ignition sources

14 / 72
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 wired 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 IP67, 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.
