Circuit Protection
Your ZebraStat provides circuit protection in
two ways. Each uses a solid-state, automati-
cally-resetting circuit breaker device. The
white test lead is protected with a 3 Amp de-
vice. You can learn more about its use in the
“Troubleshooting Electronic Boards” section.
The second device provides an overall pro-
tection for the ZebraStat. It is rated at ap-
proximately 5 Amps at 28 Volts. (150VA)
If you inadvertantly hook up the
ZebraStat’s
power input leads using an incorrect ‘polarity’
and attempt to use the Activation Mode, or if
you allow a loose ‘hot’ lead to touch ground,
you will probably ‘trip’ this circuit protection,
shutting down the ZebraStat, and turning on
the red TRIP LED. The unit
will remain in the
tripped condition until you remove all power
to the unit for about 15 seconds. Before re-
connecting, discover and correct the condi-
tion that caused the trip in the first place.
This protection device is not meant to protect
the unit from higher voltages than 28 Volts.
