WARNING AND CAUTION
WARNING
WARNING refers to possible injury to the user or significant damage to the meter if the user does
not follow the procedures.
CAUTION
CAUTION refers to restrictions and rules with regard to preventing damage.
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 the 600-ACSM 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 unit is installed. Many inverters have a ‘sleep mode’ in which their voltage potential may not be
detectable with measuring equipment.
If an inverter is installed on the vessel, it must be stopped and rendered inoperable before the unit
is installed.
Verify that no other DC or AC is connected to the vessels wiring before installing the unit.
If the meter must be removed, connect the current transformer leads together before restoring
power to the AC system.
CAUTION
The back of the unit is not waterproof. Do not install where the back of the meter is exposed to
water.
