3.3 Expected lifetime
HFXE LED: At Tc <55°C the expected lifetime to survival of >90% of units exceeds 75.000 hours
Expected lifetime of the system HFXE LED and ARC depends on the following parameters:
•Operation at maximum ambient temperature will decrease lifetime
•Number of switching cycles –
oFrequent switching causing rapid temperature change will decrease lifetime
•Number of thermal cycles –
oFrequent and rapid cycling from cold to warm will decrease lifetime
•Constant operation in stabile low to medium temperature will increase lifetime
•Mains supply quality, susceptibility for high-voltage spikes in the supply lines
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.
Do not energize circuit before all components and LED-modules are connected properly.
In case of no function or malfunction: first de-energize the circuit. Disconnect mains and battery
supply before LED modules are disconnected.
•Connect all components, battery and LED module.
•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 LED
module properly connected.
•Energize the unit from mains supply.
oThe LED module will light up in normal mode.
•Test of HFXE; The battery must be properly charged before this test –min 24h.
oDisconnect mains supply, all phases.
oThe HFXE will switch the internal source to battery supply, and LED module will
light up in reduced mode.
oThe preset emergency operation time 90 or 180 minutes will be completed before the
HFXE will switch of the LED module.
•When mains supply is reconnected the HFXE will stop battery operation and return to normal
mode and normal light output.
•Disconnect battery before mains before storage. Battery should be fully charged and
disconnected before storage longer period.
4.1 Schedule of limitations
-The temperature of the TC point must not be exceeded
-The minimum operating temperature of the
o HFXE LED-driver is -52°C

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.
-Charge current is limited to max 200mA
-Charge voltage is limited to 9,3V

Barel reserves the right to change technical specifications without further notice Page 5of 7
-With one fault condition of the charging system, the charging power is limited to 2W by a
transformer and the current is limited to 200mA for 11949-XXX.
-Discharge current = 0.5A - 1.75A.
-Discharge cut-off voltage = 1.0V/cell i.e. 6.0V for 7.2V 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”. 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 module
connection according to marking label) ( Do not connect HFXE LED to mains supply without
LED module 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, 7,2V 4Ah (6C). Connect battery to
correct polarity of HFXE “13” and “14”. Maximum continuous charge current <200mA.
4.4 Operation
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 self-test) a single color (green) LED is used. It is recommended to use
bidirectional LED, for correct functionality of the charging indicator. For use of the luminaire
without connected battery L4 should be disconnected to ensure proper functionality of the green
LED.
For a Self-test operation, a bidirectional LED is used (RED / GREEN) connected such that OK =
GREEN. For connection of the bicolor LED the green colored LED is referred 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 LED module in emergency mode 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 are connected properly.
In case of no function or malfunction: first de-energize the circuit. Disconnect mains and battery
supply before LED modules are disconnected.
-No light in LED module when connected to mains supply-
- Make sure all components are the correct type and suitable for 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 HFXE and ARC should be replaced in case of
failure –to avoid premature failure of the other component.
-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 LED module.
- 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 LED module wires from mains supply wires
-Ground the LED-driver through a short wire connection, and if possible
separate from mains cabling internally in luminaire.
