LED Beacon LD15
English
1.0 Introduction
These certified beacons have been designed for
use in potentially explosive atmospheres and harsh
environmental conditions. The enclosures are suitable for
use offshore or onshore, where light weight combined
with corrosion resistance is required.
The housing is manufactured completely from a U.V.
stable, glass reinforced polyester. Stainless steel screws
and mounting bracket are incorporated ensuring a totally
corrosion free product.
Units can be painted to customer specification and
supplied with identification labels.
2.0 General safety messages and
warnings
All instructions and safety messages in this manual must
be followed to allow safe installation of the device. The
device must only be installed and maintained by correctly
trained site personnel/installers.

To reduce the risk of ignition of hazardous
atmospheres and shock, do not apply power to
the device until installation has been completed
and the device is fully sealed and secured.
II.
To reduce the risk of ignition of hazardous
atmospheres and shock, keep device tightly
closed when the circuit is energised.
III. Before removing the cover for installation or
maintenance, ensure that the power to the device
is isolated.
IV. Following installation, test the device to ensure
correct operation.
V.
Following installation ensure a copy
of this manual is made available to all
operating personnel.
VI. When installing the device, requirements for
selection, installation and operation should be
referred to e.g. IEE Wiring Regulations and the
‘National Electrical Code’ in North America.
Additional national and/or local requirements
may also apply.
VII. Cable termination should be in accordance with
specification applying to the required application.
MEDC recommends that all cables and cores
should be correctly identified. Please refer to
the wiring diagram in this manual (or separate
diagram provided with the unit).
VIII. Ensure that only the correct listed or certified
cable glands are used and that the assembly is
shrouded and correctly earthed.
IX. Ensure that only the correct listed or certified
stopping plugs are used to blank off unused
gland entry points and that the NEMA/IP rating of
the unit is maintained.
X.
MEDC recommend the use of a sealing
compound such as HYLOMAR PL32 on the
threads of all glands and stopping plugs in order
to maintain the IP rating of the unit.
XI. The internal earth terminal, where fitted,
must be used for the equipment grounding
and the external terminal, if available, is for a
supplementary bonding connection where local
codes or authorities permit or require such
a connection.
XII. When installing the device, MEDC recommends
the use of stainless steel fasteners. Ensure that all
nuts, bolts and fixings are secure.
3.0 Installation
General
The device can either be directly mounted using the
inserts moulded into the back of the enclosure (standard),
or an optional backstrap can be fixed to the base of the
device thus giving an optional mounting position for when
direct mounting is deemed unsuitable.
The 2 off inserts in the base of the enclosure are
designed to accept an M5 screw or bolt.
Noee:
N
For direct mounting, observe the following
formula to determine the required fixing screw
length: Length of screw = Thickness of mounting
s 10mm.
The 2 off Ø8,5mm mounting holes in the optional
back-strap have been designed to accept an M8 screw or
bolt.
