Warning and Caution Symbols
WARNING: The
symbol refers to possible injury to the user or
significant damage to the meter if the user does not follow the procedures.
CAUTION: The
symbol refers to restrictions and rules with regard
to preventing damage to the meter.
WARNING
• If you are not knowledgeable about electrical systems, have an
electrical professional install this unit. The diagrams in these
instructions pertain to the installation of M2 Digital Meters and not
to the overall wiring of the vessel.
• If an inverter is installed on the vessel, its power leads must be
disconnected at the battery before the meter is installed.
• If an AC generator is installed on the vessel, it must be stopped
and rendered inoperable before the meter is installed.
• Verify that no other DC or AC sources are connected to the vessel's
wiring before installing the meter.
CAUTION
• The back of the unit is not waterproof. Do not install where the back
of the meter is exposed to water.

    Installation 1. Make all connections to the meter’s terminal block before connecting the terminal block to the unit. Keep hands away from the terminal block when applying power to the meter. 2. As the final DC connection, insert a fuse into the in-line fuse holder on the wire to the positive (+) battery terminal. Mounting Templates Flat Mount Surface Mount...

  • Page 4 The negative lead of all the temperature sensors should terminate as close as possible to pin 1. For a simple and clean installation, use Blue Sea Systems PN 2304 as a small common bus bar for all of the meters DC negative connection. There should be one connection between pin 1 of...
  • Page 5 Note: The negative feed of all of the temperature sensors should terminate as close as possible to pin 1. Use Blue Sea Systems’ PN 2304 Mini Bus with a short 18 AWG guage wire from pin 1 to the Mini Bus.
  • Page 6 M2 Relay Connections M2 Meters contains an internal MOSFET relay that can drive external DC loads up to 0.5A. The input is protected with a thermally activated auto-reset- ting fuse that will protect against shorts. In addition, an inline fuse rated at 5A should be used to protect against shorts. In typical applications, a power source is connected to the Relay+ pin and a load is connected to the Relay Out to Load connection.

    Other Display Indications The dotted lines in T4 indicate the Hi and Lo Alarm Levels. The Hi and Lo Relay levels are not shown. If Display MinMax is on, then split triangles on the right side of the each graph indicate the minimum and maximum levels. A single triangle indicates that the minimum and maximum levels are close to each other.

  • Page 11 Setting Input Thresholds Settings for each channel’s high and low temperature thresholds are provided. The connected relay’s normal operating state will toggle (change state) if these thresholds are met. For both high and low thresholds, the activation and deactivation levels are different to prevent the relay from rapidly toggling (cycling on and off).
