Overview of Application
The ML-Series Remote Battery Switch (ML-RBS) provides high-current carrying
and switching under load.
The ML-RBS should be installed close to the battery to minimize voltage drop
to the ML-RBS.
Install a single pole double throw (SPDT) or single pole single throw (SPST)
control switch in a convenient location near other electrical controls or
companionway to allow quick access in the event of an emergency (see
Illustration on reverse).*
- Although an SPST switch may be used if desired, the use of an SPDT switch improves immunity to inadvertent switching if the switch terminals become damp.

CAUTION
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.
The illustrated wiring diagram represents a common installation and is not
meant to be a guide for wiring a specific vessel. The wiring diagram shows a
single battery bank installation.
Disconnect all negative battery connections before beginning the installation.
All unused control wires should be carefully insulated from each other and
from accidental contact using heat shrink tubing or electrical tape. External
contact or shorting between control wires can lead to malfunction.
Installation Instructions
Mounting
Install as close as possible to the battery bank. To avoid corrosion to
connecting wires and terminals, mount in a dry and protected location. Avoid
mounting directly above vented lead-acid batteries so that the Remote Battery
Switch is not exposed to corrosive gasses expelled from the batteries.
High Current Primary Circuit Connections (stud terminals A and B)
For help selecting the appropriate wire size and circuit protection rating, go
to www.bluesea.com and click the Circuit Wizard
quick link.
NOTE: Stud terminals A and B are interchangeable. A battery connection is
required on one terminal for device operation
To connect high current circuit wires:
- Connect the battery bank to one of the stud terminals marked A or B.
- Connect the load to the other stud terminal marked B or A.
- Torque the high current terminal stud nuts to 140 in-lbs (15.5 N•m) maximum.
NOTE: If switching an inverter, windlass, bow thruster, etc., the circuit
wires must have circuit protection to comply with ABYC guidelines. Wires used
for engine starting do not require circuit protection.
Control Circuit Connections (wires contained in the wire harness)
NOTE: The Remote Battery Switch is designed to be controlled by an SPDT
or SPST switch.
Use a minimum of 16 AWG wires for the Control Circuits. For help selecting the
appropriate wire size for the load cables, go to
www.bluesea.com and click the Circuit Wizard quick
link.
To connect the SPDT Remote Control Switch 2155:
- Connect pin 3 and pin 8 to +12V or +24V Power available when Remote Battery Switch is OFF. (fused)
- Connect the red control wire to switch pin 2.
- Connect pin 7 to the yellow wire.
- Connect pin 1 to ground or negative.
