Safety
1.1. Definition of Symbols
Stop (Stop Danger). This symbol warns of serious danger of severe injury to
persons. It must be strictly observed.
Attention (Warning). This symbol indicates information the non-observance of
which can lead to extensive damage to property. The safety warning must be
strictly observed.
Information. This symbol indicates key information on use. Non-observance can
lead to failure.
1.2. Safety Advice
The ELC must be installed and connected in compliance with existing regulations
and practices. This is e.g. EN 60204-1 in Europe.
Repairs on the ELC may only be carried out by the manufacturer.
The installation and starting up may only be carried out by skilled electricians.
Do not open the ELC before it is disconnected from the mains. BEWARE OF
RESIDUAL VOLTAGE! The unit may still be live up to several minutes (see label on
the ballast) after it has been switched off.

1. Safety page 2
ELC PE22B-PE35B V1.0-05.19-GB Subject to technical alterations
The ELC causes a leakage current given in chapter 6.
Safeguarding by means of leakage current protection type A and type AC
according to IEC 60755 is not permitted! The ELC operates in principle as a
frequency converter and is equipped with a mains filter whose leakage current
could activate fuse protection.
Contact to the grounding connector must always be ensured.
Additional measures must be taken to ensure that there is no danger when
touching the appliance. This could be by means of a universal leakage current
protection type B, taking into consideration the increased response threshold, or
by means of an independent equipotential connection.
1.3. Correct operation
The ELC is an electrical unit intended to be installed in the switch cabinets of
industrial high-voltage power installations. It is conceived as an electronic ballast
for the operation of lamps intended for this purpose.
Any other use is deemed as misuse. The manufacturer will not assume liability
for damage resulting from misuse.
A pre-requisite for authorised operation of the ELC is the observance of both the
operating and maintenance instructions and the safety advice.
1.4. Extended use
Extended use beyond the operating specifications as stated is not permitted.
The manufacturer will not assume liability if the equipment is used in any other
way. The operator acts at his own risk.
Any operation beyond the scope of the authorised operation is considered to be
misuse.

2. Description of functions page 3
ELC PE22B-PE35B V1.0-05.19-GB Subject to technical alterations
Description of functions
The ELC is an electronic power supply unit for the operation of gas discharge lamps with
electrical properties as described in chapter 6.
In contrast to conventional ballasts (inductive lamp ballast or transformer or transformer with
transductor), the lamp with an electronic ballast is operated with high frequency (approx.
100 kHz). The lamp does not flicker and dimming is infinitely adjustable to a range between
20 % and 100 % of the electric power or to between 15 % and 100 % of the UV radiation
respectively.
Dimming
The possibility of dimming the lamp has two advantages. Firstly the lamp can be switched to
minimum load (standby operation) during longer idle times and energy can thus be saved.
Secondly the optimum lamp power can be determined and adjusted as appropriate.
Power control
The ELC offers a high level of lamp power constancy due to its integrated power control.
Variations in operating voltage of 10 % do not affect lamp power.
Ignition device
When the lamp is switched on the ELC initiates trigger pulses to fire the lamp; a separate
ignition device is not required.
Other performance characteristics
High level of electrical efficiency.
Configuration, control and monitoring of the ELC is carried out via PROFIBUS-interface.
The ELC monitors the lamp cables for earth fault.
The lamp output potential is separated from that of the supply voltage.
The ELC is both short-circuit proof and safe in open circuit operation at the lamp output.

ELC PE22B-PE35B V1.0-05.19-GB Subject to technical alterations
Installation
3.1. Mounting of casing
The ELC must be installed in a control cabinet with at least IP 54 protection (see
EN 60529). Operation without a control cabinet or in a control cabinet with a lower
degree of protection is not permitted.
It is only permitted to install the appliance in the positions described in 3.1.1 und
3.1.2.
When installed vertically, the control connections must be positioned at the
bottom and supply connections at the top. Installation must allow for the
minimum spacing.
The ELC should not be mounted in the immediate proximity of sensitive electronic
equipment. An appropriate distance must be maintained to scatter field
transformers or other inductors.
The flow of cool air for the ELC must be safeguarded. The ambient temperature
must not exceed the values prescribed in chapter 6.
Ventilation must be provided for the switch cabinet.
The amount of air necessary is determined by the size and positioning of the
switch cabinet, the total electrical losses and the external temperature. Please
consult your switch cabinet manufacturer. For the recommended throughput of
air please see the technical data in chapter 6.
Impure cooling air could affect the functionality of the ELC. This can be avoided by
installing a fine air filter.

3.3. Control- and bus connections
3.3.1. Mounting of the strain relief
Strain relief in transport position
Loosen the two screws on the cable clamp with a
2 mm hex screwdriver.
Then pull out the strain relief to the left.
Strain relief in end position
Rotate the strain relief and slide it back in from
above. Note that the washer remains between the
screw head and the strain relief.
Tighten the screws.
Attention: do not remove the two bolts holding the strain relief. They are also
fastening the board inside the ballast which might get out of position.
In addition they are specifically designed to provide a large surface for optimum
contact of the strain relief to the housing.
Attention: if it is necessary to prolong the bolts exercise extreme caution when
mounting additional parts. The built in bolts have a threaded pin size M3 to fit to
the board. This might easily crack whith high mounting torques and the ballast
would have to be replaced.
The cable lengths given in 3.3.2 might not apply anymore.
3.3.2. Connecting bus cables
In case of shielded bus cables the shielding should be attached to the strain relief.

The control and bus cables are connected by means of the plug connections available as
accessories.
The sockets are provided with threads. In combination with the screwable plugs this ensures
a safe connection e.g. in case of vibrations.
In order to minimise the danger of mixing up the control plugs, the sockets on the appliance
have been coded with the red code profiles. They are positioned according to the following
picture:
Fig. 4: Coding of the control plug
When the control plugs are delivered they are not coded
and cannot be connected in this condition! In order to
code the control plugs the corresponding code “nose”
must be removed (see Fig. 4). Pin 1 is marked by means

3.4. Comments on the safety functions of the ELC
ELC with PROFIBUS feature two
safety circuits, as shown
schematically in the picture on
the left :
Safety relay K1 with feedback
via the normally closed contact
(paragraph 3.4.1)
Monitoring of the initialisation
signal (paragraph 3.4.2)
3.4.1. Safety relay
To set the ELC ready for operation, the safety relay K1 has to be activated by applying +24V to
pin X1.3 and GND on pin X2.3.
As long as the safety relay is not activated, lamp operation is not possible! There are two
feedback paths:
a normally closed relay contact. It may be tapped on pins X2.1 and X2.2.
the [Warning Register] of the PROFIBUS-input-data (see below and paragraph 5.3: Bit 4 {Safety
Relay Open})
If the safety relay is deactivated during lamp operation, lamp operation will be shut down. After
reactivating the safety relay, the lamp has to be restarted.
3.4.2. Initialisation signal
Furthermore lamp operation will not be allowed unless +24V are applied to pin X1.1 and GND
on pin X1.2. This is an additional monitoring function for the safe operation of the installation.
The status of pin X1.1 is visualized in the [Warning Register] of the PROFIBUS-input-data (see
below and paragraph 5.3: Bit 7 {Init Signal Ok}).
If the initialisation signal is deactivated during lamp operation, lamp operation will be shut
down. After re-applying the initialisation signal, the lamp has to be restarted.
