Introduction: The Motorised Battery Switch (701-
MD) has the same mechanism as the well proven
701. The essential difference being the switching
action has been motorised.
This permits switching of battery banks remotely.
A typical installation is a key operated switch at
the helm station and the motorised battery
switch installed as close as practical to the battery
bank. (Part No for key switch: 722-KS or any
other standard On/Off switch)
Apart from the convenience of such an
installation, this arrangement permits much
shorter cable runs to starter motors and other
high current applications such as bow thrusters
and inverters. As a result voltage drop and
use of heavy cable has been kept to minimum. .

•Continuous rating: 275 Amps DC
•Intermittent rating: 455 Amps DC
•Cranking rating: 1250 Amps DC
•Maximum Voltage: 32 Volts DC
•Operation: Manual On/Off
Motorised On/Off
•Mounting: Recessed or surface
•Auto operating range 8 to 30 Volts DC
•Ignition protected

•Recommended Maximum Cable Size: 50mm.
If fitting cable in excess of 50mm the cable
must be strain relieved with an absolute
maximum of 00 or 70mm.

General Operation: The Motorised Battery Switch, (701-MD) has two modes of operation.
Auto and Manual. There is a LED located on both the battery switch and key switch (722-KS),
Indicating Battery Switch status.
Auto Operation: The 701-MD moves
from a state of “Auto Off” to “Auto On”
when the remotely mounted switch is
turned on. During the time that the battery
switch is in “Auto On” mode, the“Auto On” LED
is illuminated.
Auto operation of the Battery Switch is not
possible whilst in manual mode. If auto
operation is attempted, the LED will flash
for 3 seconds then stop. Knob must be
returned to “Auto Off” before normal
auto operation can continue.
Auto Mode LED Indications:
LED OFF: Battery switch is off
LED ON: Battery switch is on
LED FLASHING: LED flashes whilst moving
between auto on and auto off.
LED Rapid Flash: On 0.1 sec & Off 0.1 Sec:
Voltage is outside specification i.e. Less than
8 Volts or greater than 30 Volts
Manual Mode LED Indications:
LED OFF: Battery Switch is off
LED ON: Battery Switch is on
Manual Operation: The automatic
operation of the 701-MD battery switch
can be overridden at anytime by depressing
the control knob and turning clockwise
towards the “Man On”position or counter
clockwise towards the “Man Off”position.
During the time that the Battery switch is in
“Man On”mode, the “Man On”LED is
Illuminated. Refer Fig 1 for reference.
Battery Switch Labels.
The Motorised battery switch is supplied with
a generic battery label.. A range of the most
commonly used labels can be ordered
separately. Part No. 713
