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.

2.1 UNPACKING THE BOX
You will nd 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
2.2 MOUNTING THE UNIT
The unit should be mounted to a at 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
2.3 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.

2.4 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:

Before using the 3420 for the rst time, it needs to be congured with a suitable Oceanic
Systems Display Unit, or our Monex PC Software. The 3420 can be pre-congured when ordering
direct from Oceanic Systems – please state the required mode and instance when purchasing.
The following items can be congured on the 3420:
Attributing the device can be congured using the xxxx congurement unit. Which can then be
connected to the interface. Please contact Oceanic Systems for further details
3.1 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
conicts.
3.2 DEVICE CIRCUIT TYPE
The 3420 AC Monitor can be congured to operate in 1 of 4 modes.
