- Remove the front cover of the UNO-DMPLUS inverter (Refer to the quick installation guide of UNO-DM-PLUS inverter for proper removal of the front cover) -(A): Connect the connector (01) to the counterpart present on the inverter -(B): Use the tower with the spring supplied to secure the board to the chassis of the inverter using the appropriate hole (05) A B B B WARNING – Before turning on the unit, it is mandatory to close the cover of the inverter.
.2 Cable connection in inverter versions with wiring box To connect the signal cables to the accessory board is necessary to: - R emove both front covers (wiring box (05) and inverter compartment (04)) - I nsert the appropriate water-tight conduit connector on signal conduit opening (15) and tighten to the chassis to maintain NEMA 4X compliance. Conduit must be sealed using water-tight fittings to maintain NEMA Type 4X enclosure integrity.
To connect the wires to the Alarm (04), RS485 and REM (06) connector terminals: 1) W ith a flathead screwdriver, hold the button corresponding to the contact to be wired. 2) I nsert the cable. 3) R elease the button and check the cable seal. cable are listed in the table below: Type Cable diameter CAT 5E or greather 6 mm max.
UNO-DM-COM KIT Characteristics and dimensioning of the cable for alarm and remote control contact: The characteristics that the cable must possess are indicated in the following table: AWG / mm² Operational Operational voltage temperature 24 - 16 0.2 - 1.5 ≥300 V J4 DRM0 120 TERM. +R RTN RTN +T/R -T/R C N.C. N.O. MP1 06 J2 REM RS485 J4 Where required, it is possible to activate the DRM0 function by configuring the Jumper for the activation of the DRM0 function (03) in the “ON” position.
