1. Safety instructions
1. Read this leaflet carefully before commencing to install the RH unit and retain it for
future use. Installation can only be carried out by suitably qualified personnel.
2. Check the certification to ensure that the Zone, mains supply, ambient temperature
present and ‘T’ rating are suitable for the environment the unit is being installed in.
3. DO NOT open when energised.
4. If the RH unit is to be installed in areas of high vibration, please consult with Nemalux.
5. The RH unit housing is constructed from marine grade aluminium and toughened glass,
gaskets are silicone sponge, black encapsulant and o rings are silicone rubber, internally
some components are non-metallic. The end user must ensure that these materials are
suitable for the environment the RH unit will be installed in; Zone 1 and Zone 2 Hazardous
areas.
6. Check certification nameplate on side of floodlight/highbay to ascertain type of threaded
cable entry on the luminaire. Select suitably certified ATEX/IEC Ex /UKEX cable glands and
stopper plugs, these must be parallel thread, have a minimum of 5 full thread
engagement and be of a medium/fine tolerance to ISO965-1 and ISO965-3. The cable
entry devices selected must maintain the IP rating of the luminaire
7. The incoming mains cable should not exceed a temperature rise of 20°C above the
ambient conditions; select suitable cable.
8. To ensure the safety of the equipment, ensure that the ‘flamepath’ on Zone 1 variants
are free from any corrosion. No repairs are possible to flameproof joints – if in doubt
please consult the manufacturer.
9. External fasteners must have a yield strength of at least 600N/mm2
10. On Zone 1 variants the LED assembly contains no user serviceable parts, the luminaire
must not be operated without all the individual LED polycarbonate covers in position, the
IP66 rating must be maintained.
11. When the unit is installed correctly and in accordance with these installation instructions it
will not harm humans or animals.

2. Installation
Mounting RH Unit
1. To meet the requirements of certification a MINIMUM of 2 fixing points must be used,
the fixing points must be suitable for the conditions of use.

3. Open terminal block enclosure
4. Installer should earth the unit separately – an internal and external earth point are
provided as standard
5. Connect wires to mains supply.
6. If the unit is opened for any reason, disconnect mains
7. All RH floodlights/highbay have terminal blocks suitable for looping 4mm2 cable,
only one cable should be connected to each terminal block connection – when incoming
cables are installed a creepage and clearance of 5mm and 4mm respectively.
8. To use DALI/Dimming interface, connect the DALI terminals on the terminal block
9. Ensure no cables are trapped and gasket is seated correctly and replace terminal
block cover. Tighten to 4Nm
10. If carrying out Insulation Resistance tests the normal method of insulation testing is
to connect Live and Neutral together and test between this point and Earth to
prevent the risk of damage to the electronic control gear.
Wire the Mains cable into the terminal block. Provision has
been made for this and identified as the E (Earth), L1
(Switched Live), L2 (permanent live) and N (Neutral)
terminals. There are two pairs of contacts for each of these
to facilitate a mains cable that can be looped in and out of
the unit. The L2 terminals on a standard unit are not
electrically connected but allows them to be used on the
same circuits as emergency bulkheads.

3. Maintenance
1. It is essential that all RH units are maintained in accordance with the
requirements of the EN60079-17 standard: (Electrical apparatus for explosive gas
atmospheres – other than mines).
2. IMPORTANT. No modifications are permitted to the unit, all spare parts must be
purchased from the manufacturer, unauthorized modifications or spare parts will
invalidate certification and make the equipment dangerous.
3. Isolate the RH unit from the mains supply and allow to cool before carrying out any
maintenance work.
4. The unit has 2 independent power supplies; in the event that a power supply needs to be
replaced remove the flameproof cover to get access to the power supply. Remove the
power supply from the mains terminals then remove LED red and black wires. If
replacing a power supply on a Zone 2 luminaire the orange silicone gasket should be
replaced at the same time to maintain the restricted breathing properties of the
enclosure, the gasket is located in the machined groove, all replacement gaskets
must be supplied via Nemalux
5. Disposal of packaging, RH units and old LED assemblies/power supplies should be
carried out in accordance with national regulations.

5. Troubleshooting
1. Ensure the two LED boards are correctly wired to terminal block. Red to Red : Black to
Black – paired cables
2. Ensure Mains input is correctly connected.
3. Ensure Mains Input is turned on at the source.
4. If LED panel fails to light is it possible to identify if problem is with LED panel or power
supply by swapping LED cables to opposite power supply to help identify problem.
