ELECTRICAL CONSIDERATIONS
3.4. Optional cable clamp
For OPTOTRONIC
®
OTp 35 and OTp 45 types, an optional
cable clamp is available for order. This cable clamp can
be snapped onto the ECG and thus turns it into an ECG
suitable for independent installation with strain relief.
When using this cable clamp, luminaire design according
to IEC 60598-1 class I and class II is possible. In this regard,
functional earth may have to be observed as detailed above.
Please also note the installation requirements as supplied
with the cable clamp.
For more information on the cable clamp, see chapter
1.2.3. Accessories (p. 7)
.
3.3. Wiring in class I and class II luminaires
Depending on the design of the luminaire according to
class I or class II requirements, a protective earth con-
nection can be established for the OPTOTRONIC
®
ECG.
The functional earth (equipotential connection) may be
connected to the ECG to improve EMI behavior.
For these requirements, see the illustrations below.
Since the power supplies are SELV-equivalent, no
ad ditional electrical insulation has to be provided for
the LED module.
Earth connection is mandatory in class I luminaires and
improves EMI compliance according to EN 55015.
In class II luminaires do not connect earthing terminal.
