Operating Notes for Emergency Lighting Control Gear

Specification Product Safety

Supply Voltage: 220-240Vac 50/60Hz The control gear relies on the luminaire enclosure for protection against accidental contact
Ambient Temperature Range: 0°C … +50°C with live parts. It is considered as built-in, and provides basic insulation between live parts and
its external surfaces. It does not require the use of a protective earth.
Control gear complies with IEC/EN 61347-2-7.
Basic insulation is provided between live supply and DALI control conductors, and reinforced
Dimensions insulation is present between the live supply and the battery circuit.

The control gear battery charge circuit has deep discharge and short circuit protection that will
continue to charge batteries once a short circuit is removed.

The luminaire must be identifiable with those responsible for integration of the control gear.

The live supply is protected against failure of any unit with an internal 800mA non-replaceable
136mm fuse. The battery is protected with an internal 2A non-replaceable fuse.
148mm The control gear is suitable only for use with LED modules. Ensure correct polarity of the
power LED. Do not operate with the power LED disconnected.

The permanent live supply should not be interrupted during the initial charge period.
Batteries Standard variants must be allowed to charge for 24 hours before rated duration can be
achieved.
NiCd variants continually charge batteries at their nominal rate.
DALI / AutoTest variants will begin an automatic commissioning process on initial power-up
NiMH variants apply pulse-charging after the commissioning period to prolong battery as outlined in the table below:
life and reduce energy consumption. During commissioning, the emergency function will be inhibited.

Permanent damage to the control gear may occur if battery polarity is reversed. LED Indication Stage / Period Status

Power LED, Battery, Indicator LED, and Test Switch terminals are classified as SELV.
The wiring to these should be kept separate from inputs, or double insulated in order to maintain SELV compliance.
Allowed time in rest mode: 15 days – 2.2Ah NiMH,15 days – 2Ah NiCD, 30 days – 4Ah NiMH
Low voltage leads should be separated from mains leads for good EMC performance. Maximum lead length for the Indicator LED and Test Switch is 1m.
To avoid damage to the control gear, all wiring must be protected against short circuit to earth, and appropriate grommets or cable glands should be used where necessary.

*SWITCHED LIVE Available on all product variants. Enables optional maintained operation. SWITCHED LIVE must be on the same phase as UNSWITCHED LIVE.
*DALI Available on DALI variants only. For use with compatible monitoring and control systems that support BS/EN 62386 part 202.
*TEST SWITCH Available on all product variants enabling connection of a low voltage test switch.
