Application
Refer to the mini BLC 4DI product sheet (see chess.nl) for the product specifications and
environmental conditions.
Installation
•Install the mini BLC 4DI in the direct neighborhood of other Mymesh products.
•Mount the mini BLC 4DI with 2x M3 screw/bolt (76 mm distance).
•Use maximal 1.5 mm2 wiring for all connections. Push the wires completely into the terminal
block. Use wire end sleeves when using flexible wires.
•Connect the 230VAC supply voltage to the mini BLC 4DI. Connect one up to four contact
inputs and the common GND to external voltage free contacts (see wiring diagram below).
•One mini BLC 4DI controls one luminaire.

Antenna mounting
•Connect the supplied antenna to the antenna connector.
•The antenna is used for wireless communication with other Mymesh products. Operation of
the antenna should not be disrupted.
oDo not mount the antenna inside a metal housing, flat on a metal surface or directly
next to a large metal object.
oSome glass and plastic materials such as safety glass, tinted glass and double glass
influence the operation of an antenna.
oUse a plastic, polycarbonate or fiberglass housing without carbon
oMount the antenna outside the housing/cabinet if necessary. Ensure that the
thickened part at the end of the antenna is positioned outside a housing plus 1.5cm of
the antenna cable. Use a grommet for protection of the antenna cable.

•Depending on the installation of the antenna in the housing/cabinet the range is damped to a
greater or lesser extent. The range of the antenna is divided into four categories:
o–75 to 100% antenna range for situations where luminaires are installed
far apart in an open space (approx. 30-50 meters) OR
for situations where luminaires are installed in close proximity (approx. 20-30 meters)
in complex buildings with a lot of damping through walls, partitions and ceilings
o–50 to 75% antenna range is acceptable for situations where luminaires
are installed in close proximity (approximately 10-20 meters) in buildings with limited
attenuation due to partitions.
o–25 to 50% antenna range is acceptable for situations where luminaires
are installed in an open space in close proximity (approximately 10-20 meters).
o–no antenna range. Do not apply.
•The following installation examples of the antenna are for illustrative purposes. Contact
Chess in case of doubt.
