Special Conditions for Safe Use

Repair of the flame path / cemented joints is not permitted.

The enclosure is non-conducting 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 that might cause a build-up of electrostatic charges on non-conducting surfaces.

The stainless steel beacon guard is not earthed and may generate an ignition- capable level of electrostatic charges. It has a capacitance of 10pF according to EN/IEC60079-0, clause 7.5.

Product Mounting and Access

Location and Mounting

The location of the beacons should be made with due regard to the area over which the warning signal must be visible.
They should only be fixed to services that can carry the weight of the unit.

The beacons should be securely bolted to a suitable surface using the 9.4mm diameter bolt holes in the base of the unit (see figure 2).

Access to the Flameproof Enclosure

In order to connect the electrical supply cables to the beacon it is necessary to remove the flameproof cover to gain access to the flameproof chamber. To access the Ex d chamber, loosen the M4 grub screw on the beacon cover. Open the enclosure by turning the beacon cover counterclockwise and remove the cover, taking extreme care not to damage the flameproof threads in the process (see figure 3).

On completion of the installation the flameproof threaded joint should be inspected to ensure that they are clean and that they have not been damaged during installation.

Flameproof threaded joints are not intended to be repaired.

Ensure that the ‘O’ ring seal is in place and undamaged.

When fitting the flameproof cover ensure the thread is engaged correctly. Fully tighten the cover all the way, ensure no gap is visible between the cover and base of the beacon enclosure. Tighten the M4 grub screw.

Installation Requirements

Installation Standards Compliance

Attention: Disconnect from power source before installation or service to prevent electric shock.

The beacons must only be installed by suitably qualified personnel in accordance with the latest issues of the relevant standards.

ATEX / IECEx & UKEx installation 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.

NEC / CEC Installation Standards

Cautions
Attention: Installation must be carried out by an electrician in compliance with the National Electrical Code, NFPA 70 or CSA 22.1 Canadian Electrical Code, Part I, Safety Standard for Electrical Installations, Section 32. / L’installation doit exclusivement être réalisée par du personnel qualifié, conformément au code national d’électricité américain, NFPA 70 ou CSA 22.1 Code canadien de l’électricité, première partie, norme de sécurité relative aux installations électriques, Section 32.

Attention: Disconnect from power source before installation or service to prevent electric shock / Débranchez-le de la source d’alimentation avant l’installation ou l’entretien pour éviter tout choc électrique.

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.

Cable Selection and Connections

When selecting the cable size, consideration must be given to the input current that each unit draws (see table 1), the number of beacons on the line and the length of the cable runs. The cable size selected must have the necessary capacity to provide the input current to all of the beacons connected to the line.

Electrical connections are to be made into the terminal blocks on the PCBA, using solid wire 0.5-4mm2 / AWG 20-12 or stranded wire, sizes 0.5-2.5mm2 / AWG 24-14. Wire insulation needs to be stripped 8mm. Wires may be fitted securely with crimped ferrules.

Terminal screws need to be tightened down with a tightening torque of 0.45 Nm / 5 Lb-in. A 6-way terminal blocks is provided on the AC Beacon: 2-off Live, 2-off Neutral terminals and 2-off Earth terminals in total. A 6-way terminal blocks is provided on the DC Beacon: 2-off +ve, 2-off -ve terminals, 1- off S2 (Stage 2) and 1-off S3 (Stage 3).

When connecting wires to the terminals great care should be taken to dress the wires so that when the cover is inserted into the chamber the wires do not exert excess pressure on the terminal blocks. This is particularly important when using cables with large cross-sectional areas such as 2.5mm².

Earthing

Please note that for AC supply voltage product versions the Earth terminal on the PCBA does not provide an earth connection to the product enclosure. The enclosure must be independently earthed using either the external or internal earth fixing point, (see fig 5 and notes below).

Internal earthing connections should be made to the Internal Earth terminal in the base of the housing using a ring crimp terminal to secure the earth conductor under the earth clamp. The earth conductor should be at least equal in size and rating to the incoming power conductors.

External earthing connections should be made to the M4 earth stud, using a ring crimp terminal to secure the earth conductor to the earth stud. The external earth conductor should be at least 4mm2 in size.

Cable Glands, Blanking Elements & Adapters

Follow the minimum temperature ratings of cables and cable glands according to the approvals applied.

ATEX / IECEx & UKEx Requirements

For high ambient temperatures the cable entry temperature may exceed 70ºC or the cable branching point temperature may exceed 80ºC and therefore suitable heat resisting cables and cable glands must be used, with a rated service temperature at least as stated below:
