Start-up
• Place the dimming actuator onto the DIN rail (see
fig. 3). Make sure that you can read the letters on
the device and display and that the connecting
terminals of channel 1 and 3 are at the top.
• Make sure that the catch spring (G) engages
properly and that the device is securely seated on
the rail (see figure 4).
• Wire the device according to the connecting
diagrams in figure 6 or 7.
• Connect
corresponding terminals (F and H), the dimmed
phase (to the consumer) to terminal (J) as well
as the neutral conductor to the terminals (I) (see
figure 6+7). You can connect any types of phase
conductors (L1, L2, L3).
The self-supply of the dimming actuator as well
as the supply of the third channel are established
via terminals L/3L and N/3N.
The connections of the neutral conductor (I) are
not connected to each other within the device.
Therefore, all three terminals (1N, 2N, N/3N) must
be connected to the neutral conductor. If three
lamp circuits are fused via separate residual-
current
conductors must be connected as well.
