Blue Sea Systems 7725 SafetyHub 100 Fuse Block - Manual (Page 2)

Wiring Diagram Installation Instructions
Mounting
Install the SafetyHub 100 in a readily accessible location as close as possible to
the battery. 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 SafetyHub 100 Fuse Block is not exposed to corrosive gasses from
the batteries. Where possible, mount the SafetyHub 100 in a vertical orientation.
For help selecting the appropriate wire size and circuit protection rating, refer to
the Circuit Wizard at www.circuitwizard.bluesea.com
High Current Input Connection
To use the SafetyHub 100 as an unswitched fuse block, connect the positive
battery terminal directly to the input stud on the SafetyHub 100. To use the
SafetyHub 100 as a switched fuse block, connect the output of the battery
switch to the input stud on the SafetyHub 100. Torque the SafetyHub 100 input
connection to 15 ft-lb.
AMI ® /MIDI ® Fuse Circuit Connections
To connect high-amp loads such as an engine starting circuit, distribution panel,
or windlass, use the numbered high-amp studs.
Note: Wires used for engine starting do not require circuit protection.
If you choose not to fuse the engine starting circuit, use the PN 7732 Engine
Circuit Link Bus instead of a AMI ® /MIDI ® fuse. Do not use the 7732 Link Bus
for any other purpose.
ATO ® /ATC ® Fuse Circuit Connections
To connect low-amp loads such as a bilge pump, VHF radio, clock memory, or
alarm, connect to the SafetyHub 100 plug receiver. PN 7725 includes a wire
harness for these connections.
