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.

Remote Operation

Remote Switch Operation		ML-RBS Relay State	Remote Control Switch LED
	To connect battery bank to load, or combine battery banks, press remote switch “ON”.	Remote Enabled ON (closed)	ON
	To disconnect the battery bank from the load, or isolate the battery banks that are connected, press the remote 0switch “OFF”.	Remote Enabled OFF (open)	OFF

Manual Override Operation

	To manually disconnect the battery bank from the load, or isolate battery banks that are connected, rotate the manual override knob to the right.	Manual Override LOCKED-OFF (open)	LED double blinking ON-OFF
	To manually connect the battery bank to load, or combine battery banks that are connected, rotate the manual override knob to the left then push down until latched.	Remote Enabled ON (closed)	LED double blinking ON-OFF
	To restore remote switching, manually set the RBS in the “Remote Enabled OFF (open)” position and push the remote switch “OFF”.	Remote Enabled OFF (open)	LED OFF

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:

1. Connect the battery bank to one of the stud terminals marked A or B.
2. Connect the load to the other stud terminal marked B or A.
3. 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:

1. Connect pin 3 and pin 8 to +12V or +24V Power available when Remote Battery Switch is OFF. (fused)
2. Connect the red control wire to switch pin 2.
3. Connect pin 7 to the yellow wire.
4. Connect pin 1 to ground or negative.
