INTRODUCTION The Oceanic Systems NMEA2000® 3420 AC Monitor is designed to monitor any AC source including single-phase (phase A), single-phase (phase A,B), and three-phase (phase A,B,C) This unit is designed to operate in a protected marine environment such as an engine room. It is very important that it is installed and set up correctly according to this manual.
INSTALLATION 2.1 UNPACKING THE BOX You should find the following items in the 3420 shipping box: 1 x 3420 NMEA2000® AC Monitor 1 x 3420 User Manual (This document) 1 x 3420 200 Amp AC Current Transformer 2.2 MOUNTING THE UNIT The unit should be mounted to a flat surface using 4 mounting screws.
2.4 CONNECTING THE SENSOR CABLES TO THE WAGO SOCKET WARNING: Risk of Electric Shock This device contains potentially hazardous voltages. Ensure that power is removed from all AC circuit that will be connected to the AC monitor. Do not attempt to disassemble the device. This device contains no user serviceable parts.
2.5 AC MONITOR CONNECTIONS Terminal 1 Current Transformer Phase A (2) Terminal 2 Current Transformer Phase B (2) Terminal 3 Current Transformer Phase C (2) Terminal 4 Voltage Phase A Line (Fit in-line 3 Amp fuse) Terminal 5 Voltage Phase B Line (Fit in-line 3 Amp fuse) Terminal 6 Voltage Phase C Line...
CONFIGURATION The following items can be configured on the 3420. 3.1 CONFIGURING CIRCUIT TYPE Before the AC monitor is ready to use, the type of system you will be monitoring has to be set up. When turning on the AC monitor for the first time the blue LED will flash quickly to indicate it’s not set up.
3.2 DEVICE INSTANCE It is possible to install 16 3420 AC Monitors on a NMEA2000® network so they need to each have a unique Device Instance Address. The Device Instance of each unit is set by turning the small rotary switch with a small screw driver. Valid Device Instances range from “0” through to “F”. NMEA2000®...
