Over-voltage protection
To protect electronic components from
overload, e.g. when switching inductive
loads, separate excess voltage protec-
tion devices can be used (e.g. ERCO
83819), connected in parallel on the
input side.
Notes on corrosion protection
- In-ground luminaires must be installed
such that water will drain away from the
surface of the luminaire. When installing
either in the ground directly or using an
installation housing, additional drainage
must be provided, viz. a bed of gravel.
- Ensure that the powder coating is not
damaged during installation or mainte-
nance work. Any damage, which becomes
wet, can result in corrosion occurring. It
is recommendable to use the luminaire
in ground with a pH value of 5 to 8. In
aggressive environments, the installation
and maintenance of all parts will require
appropriate protective measures. Chemi-
cals damage the corrosion protection.
Mounting (Figs. 1-3)
1. Shorten the mains supply cable to be
no more than 250mm in length from
the top edge of the screed.
2. Make the electrical connection in
an on-site connection box “M” (ERCO
33852).
The mains supply cable must be con-
nected on-site in accordance with the
required protection mode and protec-
tion class.
Notes: the electrical connection must
be made in a suitable connection com-
partment.
The cable gland must not be opened.
3. Insert the connection box “M” into
the installation housing, mounting
frame or mounting ring (Figs. 2 & 3).
The side without any cables must be
inserted first into the mounting hole
(see arrow).
4. Follow instructions in the “Setting
the beam direction” section.
Setting the beam direction
1. Remove the luminaire using a suction
cup (not supplied, ERCO 33799).
2. Undo screws “E” and remove safety
glass “F” complete with the combined
aperture mask (Fig. 4).
Note: secure the safety glass “F” to pre-
vent it from falling down.

3. Release screws “L” (these adjust the
rotation) and knurled screw “S” (adjusts
the angle of tilt). Aim the luminaire as
required and retighten all screws “L”
and “S”.
4. Re-close the housing with safety
glass “F” and combined aperture mask.
Evenly tighten the screws “E”, ensuring
the gasket is seated properly. Both the
gasket and the surfaces to be sealed
must be completely clean.
Note: replace any damaged gaskets.
5. Insert the luminaire “H” into the
installation housing, mounting frame or
mounting ring.
Notes:
Installation housing and mounting
frame: ensure that the beam direction
is correct. The luminaire can only be
installed at rotational intervals of 90°.
Mounting ring: the luminaire can be
additionally secured against twisting by
securing the mounting ring with adhe-
sive on site.

3. Undo screws “L” (these adjust the
range of rotation by +/- 5°) and knurled
screw “S” (which set the angle of tilt).
Aim the luminaire and retighten all
screws “L” and “S”.
4. Re-close the housing with safety
glass “F” and combined aperture mask.
Align the arrows on the housing and
safety glass so that they are parallel.
Evenly tighten the screws “E”, ensuring
that the gasket is seated properly. Both
the gasket and the surfaces to be sealed
must be completely clean.
Note: replace any damaged gaskets.
5. Insert the luminaire “H” into the
installation housing, mounting frame or
mounting ring.
Notes:
Installation housing and mounting
frame: ensure that the beam direction
is correct. The luminaire can only be
installed at rotational intervals of 90°.
Mounting ring: the luminaire can be
additionally secured against twisting by
securing the mounting ring with adhe-
sive on site.
Note
To remove the luminaire, use a suction
cup (ERCO 33799).
Operating instructions for LED lumi-
naires
In case of damage or a defective LED
module, the entire luminaire must be
returned to the factory.
Flashing of the LED module
It is normal for the LED module to
flicker when switching on and off.
Cleaning
Before cleaning, disconnect from
mains supply and allow luminaire
to cool!
- Regular cleaning is essential. The
required intervals and methods depend
on the mounting location, the moun-
ting situation and the ambient condi-
tions.
- Clean with a damp, soft cloth.
Cleaning the safety glass
Safety glass can be cleaned with clea-
ning agents that are also suitable for
glass-ceramic cooking hobs.
Cleaning the collimating lenses and
Spherolit lenses
Always use a soft cloth and a commer-
cially available, ph-neutral, alcohol-
free, non-abrasive cleaning agent. The
collimating lenses (secondary lenses)
are fitted directly above the LEDs with
their LED lenses (primary lenses). Like
the Spherolit lenses (tertiary lenses),
they are made of optical polymer and
are sensitive to alcohol and abrasives.
Disposal
In accordance with EU Directive
WEEE (Waste Electrical and Electro-
nic 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.
