- Cable entries whitout corrosion.
- Terminlas and blanking plugs for their firm fix.
- Lamp replacement in acc. with the manufacturer
instructions.
- Type of lamps used in acc. with the luminaire
specifications.
The flameproof of these apparatus have to be
greassed permanentlly in order to ensure it
protection in front of the corrosion, water
ingrees and seize-up problems. Cleaning rest
of greasse and corrosion no using sharp
metallic devices who can damage the surface
of the joint, and greasing they using apropiate
greasse thermically and chemically stable, like
e.g.: Molikote BR2 plus.
Ò

attention that the flameproof joints rest without
any part with coating!
Lamp replacement: Keep replacement intervals as
specified by the lamp manufacturer!

warranted.
When the assembly unit will be removed, an
additional connection will be opened via a second
switch. It separated the battery from all units, so
this battery is a stand alone source only
connected to the monitoring circuit without further
connection to any other components.
For repair electrical equipments in protection
mode is suggested follow the instructions
indicated in IEC 60079-19.
