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 buildup 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 enclosure.
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 D1xB2X 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 ¾”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.

6) Access to the Enclosure
In order to connect the electrical supply cables to the beacon,
it is necessary to open the explosion proof enclosure. Loosen
the locking grub screw in the cover and then remove the
glass dome cover assembly to gain access to the chamber.
This can be achieved by unscrewing the glass dome cover,
taking extreme care not to damage the threads when doing
so.
Warning
– High voltage may be present,
risk of electric shock. DO NOT open when
energised, disconnect power before
opening.
Warning
–
Hot surfaces. External surfaces
and internal components may be hot after
operation, take care when handling the
equipment.
