7. Secure the detector cover with the four screws.
8. Reposition the previously removed plastic frames.
9. Power the device on and set the parameters using the “RILEVA TE” app (see the relevant chapter) if the settings were not
previously made using the rotary switch.
5. Power the device on and complete the settings using the rotary switch, as described in the following paragraphs, or using
the app, ass described below.
6. Close the cover.
Use the cable glands provided to pass through and connect the cables to the terminals, as shown in the  gure and in the
connection table below. The terminals can be removed to simplify wiring.

2.4 Additional installation notes
Before commencing electrical installation and wiring, carefully read the following notes.
• Power must be supplied by a safety isolation transformer (Class 2) with no earth connection on the secondary winding.
• The cable for the relays must be sized and  tted with fuses based on the rated voltages, currents and environmental condi-
tions.
• If stranded wires are used, it is recommended to use an end terminal
• To comply with RFI immunity regulations, the communication cable shield on BOSS, mini-BOSS or other supervisors must be
earthed (e.g. to the chassis, earth bar, etc.)
• Complete all wiring before powering on.
