6. Special Applications
6.1 Outdoor Application
If you intend using electronic control gear for T5/∅ 16 mm- fluorescent
lamps in outdoor luminaires, it is important to remember that depending on
the design of the luminaire, it may be exposed to moisture and humidity.
The level of protection of the luminaire (IP ... according to DIN 40050/IEC
529) determines whether standard or special ECG have to be installed.
1) In luminaires of ingress protection type „5“ (protected against water
jets: IP 65 for example) standard ECG can be used since dampness
cannot penetrate this type of luminaire. So there is no risk of the
ECG being corroded.
2) In the case of luminaires of protection type „3“ (protected against
splash water, IP 43 for example), it is possible that water droplets
will penetrate and cause corrosion. We therefore recommend using
a protective housing (OUTKIT) over the ECGs for these luminaires.
When using QUICKTRONIC
®
of 21 mm height in combination with
OUTKIT (see Section
6.1.2) special attention should be paid to the
proper strain relief of the ECG in the OUTKIT cases.
Typical applications include lighting systems for car washes, petrol stations,
outdoor advertising, swimming poops etc.
For these applications we recommend to use the ECG in combination with
OUTKIT.
6.1.1 Installation
Instructions
In addition to general installation and wiring instructions (Section 3) the
following information is important:
• The mains connection terminals on the ECGs should point
downwards. In other words, the control gear should be installed
vertically or upside down with the base of the ECG uppermost,
otherwise horizontally with a slight incline (5 to 10°). This will
prevent condensate from collecting inside the unit and causing
short-circuits on the printed circuit board and tripping the RCD as a
result of leakage currents.
• All ECG terminals that are not protected by vertical or upside down
installation should be covered by arched metal plates or plastics
(better with regards to corrosion) so that spray water and
condensate cannot drip into the terminals and therefore into the
ECG.
• Place ECGs on spacers to protect them from dripping
water/condensation.
• To prevent water entering the control gear through the terminals
along the incoming or outgoing cables, it is best to bend the cables
ahead of the terminals (to provide a water pocket or drip point). To
ensure success, the lowest point of the kink should lie below the
level of the terminal inlet.
• A small opening at the lowest point on the luminaire is also
recommended so that condensation can escape. However, this
opening should be protected so that rain and spray cannot enter.
