WTC-LEX/-BEX protections
Model Protection
WTC-LEX-WD 6.0 A external circuit breaker
WTC-LEX-ST type C (250 VAC min)
WTC-BEX-WDLV 2.0 A external circuit breaker
WTC-BEX-STLV type C or 2.0 A fast acting high
breaking external fuse
(250 VAC min)
Use an external circuit breaker on the mains,
as specified in the table above and shown in
the figure below to protect the expansion
module against power line spikes. The
protection device must remain close to the
protected device.

Depending on models, the WTC-LEX/-BEX
expansion modules have physical
connections for ON/OFF light outputs,
dimming light outputs and 24 VDC shade /
sunblind outputs.
All output wiring must be connected using
the specified detachable connectors.
Before connecting any output equipment to
the expansion module, refer to the
installation guide of the equipment
manufacturer. Make sure the cable
performances suit the connected loads.
