-Aluminium housing fastened with 2 screws in the plastic end-caps, c-c 276mm.
4Installation
These components do not cause harm or injury when used as specified in these instructions. If this
equipment is not utilized in a manner specified by the manufacturer, the protection by the equipment
may be impaired.
Inrush current and circuit breaker characteristics/amount of units per circuit breaker must be
considered in the installation.

supply before lamps are disconnected.
·Connect all components and lamps.
-HFXE only; connect battery.
·Check that all connections are made to the correct port, tightened to the correct torque and that
no wires are loose or damaged.
-The LED module must be connected to correct polarity. Do not operate the unit without
lamp properly connected.

Technical datasheet HFX and HFXE_LED_26
-HFXE only; the indicator LED will turn green 5 seconds after first connection. This
indicates that the battery is connected and charging.
-Test of HFXE; The battery must be properly charged before this test.
- Disconnect mains supply
- The HFXE will switch the internal source to battery supply, and lamp will light up
in reduced mode.
- The preset emergency operation time 1,5 or 3 hours will be completed before the
HFXE will switch of the lamp.
- When mains supply is reconnected the HFXE will stop battery operation and return
to normal mode and normal light output.
4.1 Schedule of limitations:
- The temperature of the TC point must not be exceeded
- The minimum operating temperature of the
o HFX LED-driver is -42°C
o HFXE LED-driver is -52°C
- The HFX and HFXE LED have an output rating of 60-130V and 370mA. The current is
limited to 850mA and breaking capacity of 1500A and has been tested together with Barel
ARC LED 600 and 1200, certified Presafe 15 ATEX 6296U and IECEx PRE 15.0014U
- Charging current = 220mA, 80mA permanent
- With one fault condition of the charging system, the charging power is limited to 2W by an
transformer and the current is limited to 300mA
- Discharge current = 0.9A - 1.75A
- Discharge cut-off voltage = 4.0V for 4.8V battery.
- The fault current on the battery input is limited to 6.8A
- The indicator LED outputs has the following nominal ratings: 3V, 14mA and is limited to
5.4V and 18.3mA
- The LED-driver shall be mounted inside an Ex e luminaire and not directly exposed to light
- The terminal has a rating of 450V, Torque 0.9Nm and capacity on the screw side of one
conductor with dimensions 1.0 - 2.5mm2 rigid or flex
4.2 Electrical connection
Electrical connections of the LED-driver must be done with mains power supply off, and
disconnected. The mains supply must be disconnected by an external 2-pole switch (both phases must
be off). Connect “GND” to Protective Earth and chassis of the luminary or to a separate ground
connection. The aluminium chassis is internally connected to the gnd pin. DC input: Connect –to “N”
and + to “L/L1/L4”. HFXE: Connect L1 via switch to allow battery charging while light is switched
off. Indicator LED to be connected to 5-6 or 5-7 as indicated: (LED lamp connection according to
marking label) ( Do not connect HFX-HFXE LED to mains supply without LED lamp connected)

4.3 Battery
Batteries are to be assessed with final certification of luminaire. Charge and discharge characteristics
are suitable for use with high-temp NiCd cells, 4,8V 4Ah (4C).
4.4 Operation HFXE
Setting of 1.5h and 3h operation is selected by connection of Charging Indicator (LED) to terminals 5,
6 and 7 as described in table below.
For manual operation (no selftest) a single colour (green) LED is used. The indicator LED will be
green as long as the battery is in correct charge mode.
For a Selftest operation a bidirectional LED is used (RED / GREEN) connected such that OK =
GREEN. For connection of the bicoulor LED the green coloured LED is refered to as Anode and
Cathode
TEST:
NOTE: A full test should not be activated when the battery is empty or low capacity - this could result in a
wrong error-message.
Manual test:
By disconnecting the mains when the battery has been charged for a minimum of 24 hours.
Status of the test must be observed manually. In case of failure: repair the problem and re-test, or reset
unit by disconnecting mains.
Self-test:
By using a bipolar LED connected to the 2 of the 3 pins 5, 6 or 7 as shown above, then a self-test will be
performed. This test will automatically run a short test after 24h, then monthly and a full annual test operating
the Emergency Lamp (LAMP 1) from the battery. The test-timer includes a random-period to avoid all
luminaires to self-test at the same time. Disconnection/reset of mains and battery at the same time will reset the
test-timer. Test-program is conducted acc to IEC 62034.

5What to do if…
Do not energize circuit before all components and lamps are connected properly.
In case of no function or malfunction: first de-energize the circuit. Disconnect mains and
battery supply before lamps are disconnected.
- No light in LED lamp when connected to mains supply-
- Make sure all components are the correct type and suitable for lamp/driver type,
mains supply voltage and frequency range
- Make sure all connections are correct.
- Allow a reset of mains supply.
- Some internal protection circuits require a reset of mains supply before resuming operation
after a fault is detected.
- Contact Barel if no fault was found and the reset does not restart the unit.
- Do not attempt to open or repair these units. Both HFX/E and ARC should be replaced in
case of failure –to avoid premature failure of the other component.
- HFXE only, No light in emergency mode:
- Reconnect mains supply
- Check the indicator LED status-
- If green; There is a fault in the HFXE. De-energize the unit. Disconnect
battery before lamp. Contact Barel.
- If red or no light in indicator;
- Allow the battery to charge 24h
- Retest emergency mode.
If problems with conducted emission during EMC measurements, contact Barel for assistance.
Important issues are:
-Keep all wires short.
-Separate lamp wires from mains supply wires
-Ground the LED-driver through a short wire connection, and if
possible separate from mains cabling internally in luminaire.
