It is important that a suitable power supply is used to run the
equipment. The power supply selected must have the
necessary capacity to provide the input current to all the units.
The input current will vary according to the voltage input level.
3) Special Conditions of Use
The enclosure coating is non-conductive and may generate an
ignition-capable level of electrostatic charges under certain
extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be
subjected to external conditions (such as high pressure steam)
which might cause a build-up of electrostatic charges on non-
conducting surfaces. Additionally, cleaning of the equipment
should be done only with a damp cloth.
4) Installation
There are no restrictions on unit orientation.
The junction box must only be installed by suitably qualified
personnel in accordance with the latest issues of the relevant
standards:
EN60079-14 / IEC60079-14: Explosive atmospheres -
Electrical installations design, selection and erection
EN60079-10-1 / IEC60079-10-1: Explosive
atmospheres - Classification of areas. Explosive gas
atmospheres
EN60079-10-2 / IEC60079-10-2: Explosive
atmospheres - Classification of areas. Explosive dust
atmospheres
The installation of the units must also be in accordance with
any local codes that may apply and should only be carried out
by a competent electrical engineer who has the necessary
training.
4.1 Safe Installation Requirements:
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably
certified cable entry and/or blanking devices during
installation. If conduit is used for installation, seal conduit
within 18 inches from the first enclosure, subsequent conduit
runs must have a sealing fitting connected as close as practical
to the wall of the enclosure, but in no case more than the size
of the conduit or 50mm, whichever is the lesser.
If entries are fitted with adaptors they must be suitably certified
for the application. Fitting of blanking elements into adaptors
is not permitted.
Check that the ‘O’ ring seal is in place before replacing the
explosionproof cover.
Lens guard must be fitted for Class Division installations.
5) Location and Mounting
The location of the beacon should be made with due regard to
the area over which the warning signal must be visible. It
should only be fixed to services that can carry the weight of the
unit.
The D1xB2LD2 beacon can be mounted using one of three
methods.
1. The beacon can be surface mounted by removing,
rotating and reinstalling the stowed mounting lugs. These
are suitable for 6mm diameter fixings.
a. Remove 2 x M5 fasteners per
mounting lug
b. Reverse and rotate lug and
reseat onto enclosure
c. Secure lug using the 2 x M5
Fasteners
2. Alternatively the beacon can be conduit mounted using
the 3/4”NPT entry on the base of the unit.
3. Additionally, the beacon can be mounted using the ratchet
adjustable stainless-steel wall bracket assembly. This is
available as an accessory – part code: SP77-0001.
