Safety Notes

NOTICE!
Installation must only be performed by authorized and specialized personnel!
CAUTION!
Electrostatic discharge (ESD)! Electronic components could become damaged.
Ground yourself using a wrist strap or take other suitable actions.

Functional description

FLM-420-O2 Output Interface Modules have two semiconductor outputs (OC) for controlling external devices. The
outputs can be switched independently, are electrically isolated from the LSN loop and protected against short
circuits. Power can be supplied to consumers either separately for each output, via LSN, or externally.
The FLM-420-O2-D is installed on a DIN rail in accordance with EN 60715 with enclosed adapter (see Figure 1,
Page 4; removal, see Figure 2, Page 5).
Address setting
Fit a rotary switch in the required position using a pan head slotted screwdriver (see Figure 4, Page 6).
