before installation and commissioning
and hand over to the customer for re-
tention.
General safety information
Warning!
Risk of electric shock!
Never connect several ERCO Minirail
48V DC SELV power supply units in
series! The voltages would add up and
become hazardous.
Warning!
Fire hazard!
- The maximum current load of the
track and accessories is 10A.
- ERCO power supply units must not be
covered with insulating materials as they
may overheat. Observe the minimum
clearances when installing in closed
rooms (Fig. 2).
- To avoid short circuits always fit the
free end of the track with the end plate
(accessory).
Attention!
- The electrical contractor is responsible
for checking the electrical, mechanical
and thermal compatibility between the
track system and the luminaires fixed
to it.
- Installation requires specialist electri-
cal knowledge and must only be carried
out by an approved specialist.
- When installing, always observe the
national installation and accident pre-
vention regulations.
Intended use
- ERCO 48V power supply units are only
approved for use in dry indoor areas.
- Installation and operation is only per-
mitted together with track, luminaires,
adapters and accessories tested and
approved by ERCO.
Preconditions
The following components/accessories
are the minimum required for the con-
struction of a simple Minirail 48V track
system (Fig. 5):
Track
Live end (also required if the power sup-
ply unit is mounted above the track!)
End plate
Power supply unit
Fixing material (on site) and/or fixing
accessories
Mounting information
You can mount ERCO 48V power supply
units in the ceiling, on the ceiling or
above a track.
A live end is also required when mount-
ing above the end of a track.
Electrical connection (Figs. 7-9)
- Installation of the electrical Minirail
48V track and accessories must not be
carried out under load. Always switch
off the power supply units before carry-
ing out installation work.
- In order to avoid interference you
should avoid secondary-side switching,
i.e. between the power supply unit and
the live end.
Line dimensioning
- The cable length between the ERCO
power supply unit and the live end must
not exceed 10m.
- Connection with a 2x 2.5mm2cable.
If the distance to the track is shorter, a
smaller cross-section may possibly be
selected.
- When inserted laterally into the live
end, the outer diameter of the connec-
tion cable must not exceed 10.6mm.
Flexible cables
Flexible cables can be connected with-
out further measures. To do this, open
the terminal with a small screwdriver
before inserting the conductor.
ERCO 48V power supply units 250W
A maximum of 2 ERCO power supply
units each with the same power may be
connected in parallel. This doubles the
maximum usable power.
Attention! Other wattages must not be
connected in parallel!
Attention! Observe the polarity when
connecting two power supply units in
parallel.
Warning!
Fire hazard!
Never connect power supply units in
series because the voltages add up and
may reach a dangerous 96V and the
luminaires may also be damaged.
- When installing the cover, make sure
that the cables are not crushed or dam-
aged.
- Always check the system for short
circuits before switching on.
Operating instructions
Luminaires do not work
Cause: too many luminaires mounted
Measure: remove individual luminaires
Cause: short circuit in the system.
Power supply unit goes on malfunction.
Measure:
- eliminate short circuit / remove excess
luminaires.
- Disconnect the supply of the power
supply unit and switch it on again.
Switching off and on again may also
be necessary if a luminaire with a load
of <5W is installed on a live track.
Cleaning
Always clean carefully using a soft
cloth and a commercially available,
ph-neutral, alcohol-free, non-abrasive
cleaning agent.
Disposal
In accordance with EU Directive
WEEE (Waste Electrical and Elec-
tronic Equipment), luminaires must not
be disposed of with other household
waste. At the end of their life, lumi-
naires must be taken to the appropriate
local facility available for the disposal
or recycling of electronic products.
