•The mains voltage must corre- spond to the permissible voltage on the type plate (1)!

•Please ensure that the instal- lation is carried out according to the valid regulations.

•Please assign terminals as indi- cated!

•Remove screws (5) and lift off hou- sing top (4) paying attention to the cable.

•Unplug connector (7)from terminal on control PCB (8).

•Fit board holder (2) with power sup- ply board into the housing top (4).

Connect power supply

•Unscrew union nut (6) and remove blanking disk (12)

•Guide a 3-core cable (9) for power supply through screwed cable fitting and connect to board terminal KL1 or KL4.

•Guide a 5-pole cable (10) for poten- tial-free contact and for external test button through screwed cable fit- ting.

Terminal assignment in the case of Vac devices: L = phase conductor (black), N = neutral conductor (blue), PE = protective earth conductor (green/yellow)

Note: There is no metallic isola- tion between terminals KL4.1-6 or KL 5.1-2 and the condensate area. In the case of 24 Vdc operation, do not connect +24 Vdc to frame because the internal housing potential of the device is negative.

*) When supplying several BEKO- MAT 21 units simultaneosusly from a single 24 Vdc source we recommend: connect operating voltage preferably to KL4.4 + KL4.5 instead of KL4.1 + KL4.2 while observing the polarity.

Assembly

•Pull cables (9+10) tight and screw down cable fittings(6)

•Move board holder (2) with power supply board upwards (must click into place).

•Plug connector (7) to terminal on control PCB (8).

•Slide housing top (4) with board holder (2) into the guiding grooves.

•Tighten the screws (5).
