Oceanic Systems NMEA2000 AC Monitor
INTRODUCTION
The Oceanic Systems NMEA2000® 3420 AC Monitor is designed to monitor any AC source including single-phase (phase A), two-phase (phase A, B), three-phase (phase A, B, C) and split-phase (phase A, B). 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. Please read and follow the installation and setup instructions carefully to achieve the best results.
FIRMWARE REVISION
The information in this manual corresponds to firmware revision 1.00

INSTALLATION
UNPACKING THE BOX
You will find the following items in the shipping box:
- 1 x 3420 AC Monitor
- 1 x 3420 User Manual (This document)
- 1 x 3423 200 Amp AC Current Transformer
- 1 x Deutsch Connector and Crimps Pack
MOUNTING THE UNIT
The unit should be mounted to a flat surface using 4 M4 mounting screws. The
unit dimensions and mounting hole locations are shown on the following
drawing.
Note: Whilst the unit is designed to be water resistant, it should be
mounted away from sources of condensation and moisture
CONNECTING THE NMEA2000® CABLE
The unit is connected to the NMEA2000® network by the 5-way micro-C socket on
the front. Carefully attach the plug of the network drop cable to this socket
and tighten by hand until it is fully seated. Take care to match the
orientation of the pip inside the socket to the recess inside the drop cable
plug. The other end of the drop cable should be connected to a suitable Tee
connector on the NMEA2000 network backbone cable.
CONNECTING THE VOLTAGE & CURRENT TRANSFORMER INPUT CABLES TO THE DEUTSCH
CONNECTOR
WARNING: RISK OF ELECTRIC SHOCK
This device contains potentially hazardous voltages. Ensure that power is
removed from all AC circuits that will be connected to the AC monitor. Do not
attempt to disassemble the device. This device contains no user serviceable
parts. Connecting the AC monitor must be performed by QUALIFIED
ELECTRICAL ENGINEER ONLY.
The cables from the power-source are connected to the AC Monitor using a
DT15-12PA Deutsch Connector. Each wire should be stripped and crimped with
matching socket crimps (PN: 5099 Male Deutsch Adaptor Kit). Connections to a
mating Deutsch socket housing should be made as in the following table:
DEUTSCH CONNECTOR PINOUT

| Terminal 2 | Neutral |
| Terminal 3 | No Connection |
| Terminal 4 | Current Transformer Phase C – |
| Terminal 5 | Current Transformer Phase B – |
| Terminal 6 | Current Transformer Phase A – |
| Terminal 7 | Current Transformer Phase A + |
| Terminal 8 | Current Transformer Phase B + |
| Terminal 9 | Current Transformer Phase C + |
| Terminal 10 | No Connection |
| Terminal 11 | Voltage Phase A Line |
| Terminal 12 | Voltage Phase B Line |
CONFIGURATION
Before using the 3420 for the first time, it needs to be configured with a
suitable Oceanic Systems Display Unit, or our 3175 USB to CAN adaptor
alongside our PUMA PC Software. The 3420 can be pre-configured when ordering
direct from Oceanic Systems – please state the required mode and instance when
purchasing. The following items can be configured on the 3420: Device Instance
and Circuit Type.
Please contact Oceanic Systems for further details
NMEA DEVICE INSTANCE
You can select a unique device instance up to 254. The data instance will
match the device instance. Data instances and device instances must be unique
on a network to avoid data conflicts.
DEVICE CIRCUIT TYPE
The 3420 AC Monitor can be configured to operate in 1 of 4 modes.
| Phase Mode | AC Circuit Type |
|---|---|
| 1 | Single Phase |
| 2 | Two Phase |
| 3 | Three Phase |
| 4 | Split Phase |
- Single Phase Connection
- Two Phase Connection
- Three Phase Connection
- Split Phase Connection

Note: The “Line to Line” voltage values on PGN’s PGN127747, PGN127748 and
PGN127749 are calculated from the “Line to Neutral” voltage.
Note: The frequency values on PGNs PGN127747, PGN127748 and PGN127749 are
measured from the voltage lines when in range of 40Hz – 70Hz, if the frequency
sways outside this range the frequency will be transmitted as 49.9Hz.
