Db = Explosion Protection Level (EPL) marking for "HIGH" level of protection. Equipment for
explosive DUST atmospheres, which is not a source of ignition in normal operation or during
expected malfunctions
1.3 Standard unit construction
The following list familiarizes you with some common unit features important to recognize:
Portable: The equipment is designed and tested to be moved when energized (in this case
without danger of ignition source capable of starting an explosion (e.g static electricity))
2P+E: Electrical system having Phase (P), Neutral (N) and Protective Earth (PE). With Extra-
Low-Voltage system is recognized as PELV (Protective Extra Low Voltage)
3P : Electrical system having Phase (P), Neutral (N) and conductor for bonding (yellow/green).
With Extra-Low-Voltage this system is recognized as SELV (Safety Extra Low Voltage).
2P : Electrical system having Phase (P), Neutral (N). With Extra-Low-Voltage this system is
recognized as SELV (Safety Extra Low Voltage). No means for bonding available.
Cable: Standard cable of the Slam® Trans–series is H07BQ-F. This cable has polyurethane
(PUR) outer sleeve. PUR withstands well chemicals as well mechanical wearing. However,
the user has an option to specify cable type in accordance with work site requirements of own.
Fuse: Slam® Trans has four fuses for protecting against dangers of electrical e.g
shortcircuits of relating equipment/systems.Two of the fuses are in the primary side (P and N
conductor of supply) protecting against supply failures. Two of the fuses are in the secondary
side (P and N conductor) protecting against failures of relating equipment connected to the
sockets of the transformer.
In case of activated fuse protection: Stop the work in hazardous area
immediately until the likely shortcircuit of relating equipment/system
has been identified and corrected.
Shortcircuit is definitely a source of ignition which may cause an
explosion !
