Power connection

Fig. 5 and Fig. 6 show the respective electrical installation. Operation of appliances type
NE12-NE32 / NE12D-NE32D requires a power choke in series (see technical data chapter 6).
These appliances are implemented where the mains supply shows a low fault level or high
supply impedance.
The lamp feeder cable shielding must be connected to the ELC. To this end the connector
has an EMC screw connection (also see: connection lamp feeder cable).
If wished, the shielding can also be connected to the lamp unit.
The connection of mains supply cables and lamp feeder cables must be
separated from control cables.
For the mains power supply quality standards in accordance with EN 50160
(mains frequency, voltage drops, transients etc.) are pre-requisite.
ELCs of type “N” (N12/N16) are not designed for operation on high impedance
mains. Therefore the one-phase short-circuit power at the supply point must be
20 times higher than the nominal power of the UV installation or than the sum of
the nominal power of all electronic loads in the same arm.
