1. Disconnect all AC and DC power

Disconnect all AC power originating on or off the vessel. This includes

inverters, generators, shore power attachments and any other device

capable of supplying AC power to the ship’s circuits.

Disconnect the main positive DC cable from all batteries to eliminate the

possibility of a short circuit and to disable the inverter while installing the

distribution panel.

2. Apply Voltage Label

All panel components are sized for 12 or 24 Volt systems. Use the labels

provided to permanently identify the system voltage and its type (DC) as

required by ABYC. Apply the appropriate voltage label to the recessed

area on the front of the panel.

3. Select mounting location and cut opening

If this panel is to serve as your main shore power disconnect circuit

breaker, select a location which is not more than 10 feet from the shore

power inlet or the electrical attachment point of a permanently installed

shore power cord as measured along the conductors of the feed wires. If

it is more than 10 feet, additional fuses or circuit breakers must be

installed within 10 feet of the shore power inlet.

Select a mounting location which is protected from water on the panel

 frontandbackandisnotinanareawhereammablevaporsfrom 

propane, gasoline or lead acid batteries accumulate. The circuit breakers

used in marine electrical panels are not ignition protected and may ignite

such vapors.

Using the panel template provided, make a cutout in the mounting

surface where the distribution panel is to be mounted. Do not yet fasten

the panel to the mounting surface.

WARNING

] These instructions are intended to provide assistance with the

installation of this product, and are not a substitute for a more

comprehensive understanding of electrical systems. We strongly

recommend that a competent electrical professional perform the

installation of this product.

] If either the panel front or back is to be exposed to water it must be

protected with a waterproof shield.

] The panels must not be installed in explosive environments such as

gasoline engine rooms or battery compartments as the circuit breakers

are not ignition protected.

] The main positive connection must be disconnected at the battery post to

avoid the possibility of a short circuit during the installation of this

distribution panel.

] The shunt must be installed in the negative line to avoid damage to the

meter. Positive voltage applied to digital meter terminals #4 and #5 will

cause damage to the meter not covered by warranty.

] The vessel’s shore power cord must be disconnected form shoreside

power before installing this electrical panel.

] If an inverter is installed on the vessel its power leads must be

disconnected at the battery before the panel installation. Be aware that

many inverters have a “sleep mode” in which their voltage potential may

not be detectable with measuring equipment.

] If an AC Generator is installed aboard it must be stopped and rendered

inoperable before the panel is installed.

] Verify that no other AC source is connected to the vessel’s wiring before

the panel is installed.

Installation Set Up

1. Select positive feed wire and negative return

Determine the positive feed (red) and negative return (black or yellow)

wire size by calculating the total amperage of the circuits that will be

routed through the panel. Blue Sea Systems’ electrical panels are rated

at 100 amp total capacity. The positive feed wire must be sized for 3%

voltage drop at the 100 amp panel rating or the maximum amperage

that will be routed through the panel in any particular installation,

whichever is less. It is recommended that the positive feed wire be sized

for the full panel capacity, which, in most cases, will require at least 2

AWG wire, assuming a 10 foot wire run between the panel and the

batteries in 12 volt systems. Refer to the Wire Sizing Chart for other

situations. In the case of panels with two or more columns of breakers,

jumpers from positive bus to positive bus and from negative bus to

negative bus should be the same size as the positive feed and the

negative return wires.

Remember that the length of the circuit is the total of the positive wire

 fromthepowersourceandthenegativewirebacktotheDCNegative

Bus. Be certain that there is a fuse or circuit breaker of the correct size

protecting the positive feed wire.

2. Install shunt, negative return and positive feed

The DC digital meter shunt must be installed in the negative line of the

circuit whose current is to be measured. Refer to the DC meter

installation and operation manual prior to installing the shunt. Review the

Theory of Operation, Use, Installation Overview, Installing Shunt, Wiring

Diagram and Wire by Wire Instruction sections. Observe all warnings

regarding the shunt installation.

Connect a negative return wire from the negative bus on the panel to DC

negative and ultimately the load side of the shunt. Connect a positive

feed wire from the positive bus on the panel to DC positive. Be certain

that there is a fuse or circuit breaker of the correct size protecting the

positive feed wire.
