Remote Battery Switch (RBS)
PN 7712 / PN 7712B / PN 7714 / PN 7714B
• Magnetic Latch (ML)—draws very low current (<13 mA in the ON state and <8 mA in the OFF state) and draws
moderate current for very short time when changing state
• Silver alloy contacts provide high reliability for switching live loads
• Manual control override knob provides an added level of safety allowing control with or without power,
and offering LOCKED OFF capability for servicing
• LED output to remotely indicate switch state
• Tin-plated copper studs for maximum conductivity and corrosion resistance
• Label recesses for circuit identification
• PNs 7712 and 7714 include a Remote Control Switch PN 2155

Overview of Application

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.
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).*
The Manual Control Override Knob provides:
• an added level of safety that allows manual ON-OFF control with or without power
• LOCK OFF for servicing the electrical system
The remote LED embedded in PN 2155 indicates a closed connection between battery bank and load, or
between two battery banks when used as an emergency cross-connect.
Remote Operation. PN 2155 (SPDT, ON-ON) Remote Control Contura Switch in the ON position can either
connect the battery bank to the load or combine two battery banks. In the OFF position it can either
disconnect a battery bank from a load or isolate two batteries from each other.
To connect battery bank to load, or combine
battery banks
To disconnect battery bank from load, or
isolate battery banks that are connected
Remote LED Indicator embedded in PN 2155 SPDT ON-ON Contura Switch
indicates Remote Battery Switch state or condition as follows:
LED INDICATION REMOTE BATTERY SWITCH STATE OR CONDITION
LED is OFF Remote Battery Switch is OFF
LED is ON Remote Battery Switch is ON
Manual override--check Remote Battery Switch for switch states.
LED double blinking ON-OFF
OR Remote Battery Switch mechanical failure

Emergency Manual Control Override Operations

To connect battery bank to load, With Override Knob in (REMOTE position),
or combine battery banks push button until latched (Push to Latch On).
To disconnect battery bank from Rotate Override Knob to right to release button
load, or isolate battery banks that from Latch On mode (button pops up). Rotate
are connected Override Knob to left (REMOTE position).
Rotate Override Knob to right
To prevent remote operation
(LOCK OFF position).
With Override Knob in (LOCK OFF position),
To secure for servicing
pass cable tie through hole.
‡
Predicted performance
* Although a SPST switch may be used if desired, use of a SPDT switch improves immunity to inadvertent
switching if the controls become damp.
Set remote switch 2155 to position marked "ON".
Remote LED indicates closed connection.
Set remote switch 2155 to position marked "OFF".
