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.

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, starting up and maintenance 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 in
the ballast) after it has been switched off.

1.1 Definition of symbols

1.2 Safety advice

1 Safety page 2

ELC X-Series-V1.5-06.18-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 trip the earth leakage detector RCD.

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.

The leakage current through the interference suppression capacitors demands
as per EN 50178 the use of a second protective earth conductor in parallel to the
first one. The cross-section of each earth conductor corresponds at least to the
cross-section of an outer conductor.

The ELC is conceived as an electronic ballast exclusively for the operation of
lamps approved for this ELC type.

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.

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.

1.4 Extended use

2 Description of functions page 3

ELC X-Series-V1.5-06.18-GB subject to technical alterations

2 Description of functions

The electronic ballast ELC is designed to operate medium pressure discharge lamps as
described in chapter 6.

In contrast to conventional ballasts (inductive lamp ballast or transformer or transformer with
transductor), with an ELC the lamp is operated with high frequency (approx. 100 kHz). The
lamp does not flicker and dimming is infinitely adjustable within a wide power range (see
chapter 6).

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 400-480V  10 % do not affect lamp power. Between 310­360V a reduction of output power according to chapter 6 has to be taken into account.

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.
 Low harmonic distortion of the mains current due to integrated power factor corrector.
 Configuration, control and monitoring of the ELC is carried out via BUS-interface.
 The ELC monitors the insulation resistance of the lamp output wiring (earth fault control).
 The potential of both lamp outputs is insulated from that of the supply voltage.
 The ELC is both short-circuit proof and safe in open circuit operation at the lamp output.

3 Installation page 4

ELC X-Series-V1.5-06.18-GB subject to technical alterations

The ELC may only be installed as described in 3.1.1 and in 3.1.2, allowing for at
least the minimum spacing as shown in Fig. 3.
Horizontal mounting upside down is not allowed. All vertical mounting
orientations are possible.

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 ELC is equipped with built-in fans to ensure forced air cooling. Air ducts and
optional filters must be designed to allow the air flow described in chapter 6. The
ambient temperature must not exceed the values described in chapter 6. The
ambient temperature is measured by the ELC and will be stored within the
internal error memory.

3.1 Mounting of casing

3.1.1 Mounting of single ELC

The side surfaces of the housing contain 2 T-slots each. Fig. 1 indicates the relative interspace
of the two T-slots and distance to the outer face of the housing. The T-slots are suitable for
sliding blocks 6mm groove, M5 by Bosch Rexroth, as well as for sliding profiles (see Fig. 2) ,
the latter applicable for X6 and higher power, both available as accessories. Fig. 3 shows the
horizontal mounting orientation including the minimum spacing at the back of the ELC.
Alternatively the ELC may be mounted flush with the rear panel if a cut out for the ventilation
is ensured.

3.1.2 Mounting in a stack

Up to 12 ELC may be mounted on top of each other. To fasten the ballasts onto each other a
custom-built stacking connector has to be used (available as accessories):

3.2.2 Profile of the cable gasket X4 – X8

The IP protection level given in chapter 6 is only guaranteed if every cable’s lead-in is
completely sealed.

For this purpose the following preconditions have to be fulfilled:

 Use cables of the nominal diameters given in Table 1.

Table 1: Cable connection parameters X4-X8

3 Installation page 8

ELC X-Series-V1.5-06.18-GB subject to technical alterations

 Place the cables into the rubber

surrounds and fix them onto the clamp
with cable straps:

 Slide the front hood onto the sealing lip

and pay attention to a tight connection of
the front hood.

 If the control concept requires fewer

control and bus cables the holes of the
rubber surround have to be sealed with
blank plugs (available as accessories):

3.2.3 Overview power connections X4 – X8

Fig. 6: Power connection X4-X8

Fig. 6 shows the electrical wiring. Please consider the following aspects:

Voltage balancing: on installing several ELCs the ballasts have to be equally distributed on all
phases (e.g. 1st ballast L1/L2, 2nd ballast L2/L3, 3rd ballast L3/L1 etc.).

Protective conductors: to ground the ballast it is strongly recommended to connect to X100 at
least one PE-line with a cross section of 10mm² or two PE-lines with nominal cross section of
the mains supply lines.

Cut-Out and loop impedance: The installation of an automatic cut-out is required for line
protection. It is necessary to check the loop impedance afterwards.

Using an RCD: if a RCD is required we recommend a RCD type B. When using a RCD consider
the leakage current given in chapter 6.

Shielding:

If desired, the shielding can also be connected to the lamp unit.

 Use cables of the nominal diameters given

in Table 2 on page 11. For the mapping to
the lead-ins in the cable gasket see Fig. 8.

3.2.12 X3: BUS T-coupler

Pin assignment X3:

The T-coupler connection may be used as a BUS repeater. Via the T-coupler (see Fig. 15) the
BUS-data lines A and B as well as their reference ground may be applied (galvanically
insulated) to another slave device. The T-coupler already contains a termination according to
Fig. 14. Solely a bitrate of 500kbit is applicable. If the T-coupler connection is not required X3
may be left open.

X3 is not active in MODBUS control mode.
