Safety Features
Introduction
The Battery Adapter contains two internal non-replaceable fuses to protect from:
•
Reverse input protection
•
Over voltage input
•
Catastrophic failure
•
Shorted Outputs
•
Battery Adapter Input Power Cable Fuse
Reverse Input Protection
The Battery Adapter features a reverse input protection circuit in the event the input
from the Battery Adapter Input Power Cable is connected improperly.
Over Voltage Input
The Battery Adapter has been designed to withstand transient voltages up +60VDC
that last up to a millisecond in length.
Catastrophic Failure
In the event the Battery Adapter fails, the internal fuse will “blow” to protect the
Battery Adapter . If this happens, the unit will have to be returned for repair.
Shorted Outputs
In the event the +12VDC and/or the +9VDC outputs becomes shorted, the Battery
Adapter will automatically trip an internal fuse and shut the outputs down.
If this happens, you
must remove the +24VDC input by disconnecting the Battery
Adapter Input Power Cable for at least 1 minute. Be sure to remove the “short”
before reattaching the Battery Adapter Input Power Cable.
Battery Adapter Input Power Cable Fuse
The Battery Adapter Input Power Cable includes a built-in replaceable fuse shown
as (A) below:
Use only a Littlefuse 2A Mini Fuse type if replacement is needed.
