An optional cable clamp is available. This cable clamp can be snapped onto the ECG and thus converts it
into an ECG suitable for independent installation. Suitable cables are listed in cable clamp datasheet.

LEDset interface
LEDset allows to control the output current of the control gear (ref. to LEDset application note).
The input voltage of the Vset pin defines the output current relative to the maximum nominal
current of the control gear. LEDset interface is not isolated to the secondary side of the LED
driver output.

LEDset and DIPswitch
The output current could also be set in combination with the DIPswitch current pre-selection
(350,500 and 700mA) and the LEDset interface. In these three operation modes the ECG does
not switch off as soon as Vset exceeds 11V (no protection region).

Earth connection
Earth connection is not required but may be used to improve EMI performance of the installation.
Wrong wiring
This control gear is inherently protected against wrong wiring. The wrong connections between
LED+ with Vset and GNDset could damage irreversibly the ECG. All the other wrong wirings on
the secondary side, once removed, make the ECG work regularly. LED- and GNDset terminals
cannot be connected together.
Installation notes
The luminaire manufacturer is responsible for providing the required clearances and creepage
distances and also for the protection against electrical shock, especially for the line and load
wires according EN 60598.
Instruction sheet
Please consult the instruction sheet for further important information on e.g. wire stripping and
wiring limitations in system installations. The instruction sheet is enclosed with the device or
available upon request.
