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
• Verify that all AC sources are disconnected before connecting or disconnecting the current transformer. Failure to do so will generate lethal voltages
on the current transformer.
• 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.
• If the meter must be removed, connect the current transformer leads together before restoring power to the AC system. (P/Ns 1836 & 1838 Only)
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.
