PN 7727 / PN 7727B
PN 7727 includes a Remote Control Contura Switch,
two connector plugs and an Engine Circuit Link Bus
The SafetyHub 250 combines an ignition protected fuse block with a
remote battery switch and integrated connecting plugs. It is safe
for use on gasoline powered boats, reduces connecting wires, and
consolidates up to seven fused circuits. The SafetyHub 250
provides battery control from a remote location and a local switch for
emergency shutdown or servicing.

The SafetyHub 250 uses a SPDT ON-ON Remote Control Switch for control
from a remote location. The Remote Control Switch should be mounted
in a convenient location for quick access. It incorporates a lockout slide to
reduce the risk of accidental switching.
CAUTION Do not switch the Remote Control Switch to OFF while the
engine is running!
ACTION OPERATION LED INDICATION
To switch the battery
bank and high-amperage
circuits ON
Depress the top part
of the Remote Control
Switch actuator.
LEDs on switch and block
illuminate, indicating that
switched circuits are ON.
To switch the battery
bank and high-amperage
circuits OFF
Depress the bottom part
of the Remote Control
Switch actuator.
LEDs on switch and block do
not illuminate, indicating that
switched circuits are OFF.
Unswitched Fused Circuits
Fused circuits A, B, C, and D are always on 24-hour, (non-switched), regardless
of the Remote Control Switch and manual override switch states
(see Illustration 1.2 - System Diagram on reverse side).
Fuses
Unlatch the two yellow tabs on the fuse cover to access fuses.
The
ATO ® /ATC ® Fuse Block of the SafetyHub 250 is used for 24-hour
(non-switched) circuits. The total continuous amperage of this block must not
exceed 50A.
The AMI
® /MIDI ® Fuse Block of the SafetyHub 250 is used for the switched circuits.
The total continuous amperage of this block must not exceed 240A.
Engine Link Bus
Use the Engine Link Bus in place of a AMI ® /MIDI ® fuse for a switched engine
starting circuit. (See illustration 1.2 on reverse side.)
Indicator LED
The SafetyHub LED will illuminate when the battery switch and high-amp
switched circuits are ON.
The manual control override knob overrides the Remote Control Switch
and provides:
• An added level of safety that allows manual ON-OFF control with or
without power
• LOCK OFF position for servicing the electrical system or to disconnect the
battery bank and high-amperage circuits in an emergency
Manual Control Override Operations
Battery bank and high-amp switched circuits 1,2, and 3 only:
