Installation instructions
Point of installation
The EVG UVT must be installed and operated only in a dry, chemically and bioligically inactive environment.
Installation in vibrating parts of the system is not allowed. Hints regarding IP protection have to be
observed. The EVG UVT must be mounted upright at a grounded mounting base, which absorbs and
removes ideally the emitted heat partly. For the installation, suitable fixing screws have to be selected. It is
necessary to ensure that a distance between the screw and the printed ciruit board of at least of 3 mm is
kept. In no case, wide flat screw heads may be used, which protrude below the PCB (danger of short ciruit!).
The EVG UVT and its cabeling should be mounted separatelly from other components of the installation if
possible. That is especially important for control, signal or sensor cables with its low voltages/currents.
Connection / cabling
The EVG UVT must be connected according the terminal diagram and the front sticker. The ballast is
equipped with spring tension terminals, suitable as well for stranded wires as for rigid cables. The possible
wire gauges are spezified in the technical data. Length of the stripped insulation or ferrules must be chosen
according to the size of the terminals. The connection must be tight. Otherwise short ciruits, wrong or
loose connections could cause disfunctions and damages.
Cabeling of lamps
Each lamp must be connected to the EVG UVT with an individual cable. It is not allowed to bundle several
lamp cables into a multi-core cable. Cable connections to the lamp may not be disconnected during
operation. By no means install additonal components into the lamp supply cable, such as relays, switches,
ignitors or capacitors. The number of the clamping points in the lamp cable should be reduced to a
minimum, if possible any additional clamping should be avoided. Designated clamps and connectors must
be checked carefully, not only rearding electrical data but necessarily also relating to temperature and
environmental conditions. Clamp contacts must be protected against corrosion. Sparks at corroded clamps
could cause disfunctions or breakdown of the EVG UVT and imply fire hazard.
Because of the high frequency supply, lamp cables emitts disturbances. Hence never install mains supply
cables or control cables parallel to lamp cables. To minimize EMC disturbances, lamp cables must be kept
as short as possible. Do not exceed the maximal lenght or cable capacity specified in the technical data. It is
allowed to use shielded cables to reduce interferences. But note thus increases the cable capacity.
Installing lamp cables in parallel as well as at metallic surfaces or cable ducts raise also the capacity. The
sum of all parasitic capacities detune the oscillator circuit in the EVG UVT and can cause ignition problems
and a deviant lamp current.
Mains supply cabling
The mains supply cabling must have a low impedance and the installation of the power cable has to be
such that interferences by the emission of lamp cables are minimized. Mains supply cables must be kept
short and should not be installed parallel to the lamp cables or directly along the ballast housings.
Intersections with lamp cables should be avoided where possible. If absolutely necessary, such crossings
shall be made in right angles and a certain distance. Unavoidable noise interferences must be filtered with
appropriate measures. Basically, the interference avoidance is preferable to interference elimination.
