DC Dimmers behaving inconsistently
Use shielded cable for the bell-press wires as per the DC Dimmer data sheet if multiple DC dimmers are connected to one switch and are behaving inconsistently.
DC Dimmer power supply shuts down when initially powers up
When a DC dimmer is wired directly to an electronic transformer, some transformers enter protection mode during the initial power up. Generally, the cable length is < 100mm. You can extend the cable length between the power supply and DC dimmer by 100mm should this occur
