Blue Sea Systems Yard Vacuum PN 7712 User Manual

Overview of Application  
Marine Electrical Products  
The ML-Series Remote Battery Switch provides high-current carrying and switching under load.  
The Remote Battery Switch should be installed close to the battery banks to avoid voltage drop.

PN 7712 / PN 7712B / PN 7712100B  
PN 7714 / PN 7714B / PN 7714100B  
• Magnetic Latch (ML) - draws very low current continuous and draws  
moderate current for very short time when changing state  
• Silver alloy contacts provide high reliability for switching live loads  
• Manual override provides LOCK OFF capability for servicing and ON/OFF control with or without power  
• LED output to remotely indicate switch state  
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 a SPST switch may be used if desired, use of a SPDT switch improves immunity to inadvertent  
switching if the controls become damp.  
• Tin-plated copper studs for maximum conductivity and corrosion resistance

CAUTION  
If the ML-RBS Relay state is changed using the Manual Control Knob to a state that is  
different than the Remote Switch 2155, the relay state will automatically change to match the Remote Switch  
state after 10 minutes. The two scenarios where this will occur are shaded in the table above.
