INSTALLATION INSTRUCTIONS
The lantern should be installed according to IMO
regulations and other relevant rules and regulations for
electrical installations onboard ships.
Consider the difference in material between the lantern
(seawater resistant aluminium or brass) and the wall/mast
it is to be installed on. Use galvanic isolators whenever
there is a risk of corrosion.
Important!
The fi xing screws or bolts must be tightened fi rmly, but
excessive force will damage the lantern. It is recommended
to use acid resistant stainless steel screws/bolts.
Important!
If Tranberg stainless steel mounting bracket is used for
mounting the all round lantern, the fi xing hoop nuts must
be tightened fi rmly (illustrated with max. 2,5 kg/m with an
adjustable torque wrench), but excessive force will bend
the bracket, and bolt the bracket and the fi xing threads in
the lantern will be damaged.
The power cable should enter the lantern in such a manner
that the cable gland correctly forms a tight entrance. The
cable must be clamped near up to the lantern according
to relevant rules and regulations for electrical installations
onboard ships
