"RESET 2" button near the Alarm indicator lamps:
Pressing this button resets the inlet transfer switch and all inlet power
indicator lamps without interrupting the operation of the connected
equipment.
Fuses for the Inlet Transfer Switch
PX3TS models always contain two fuses for protecting the inlet transfer
switch. These fuses blow when the current flowing through them
exceeds the fuse rating.
When a fuse blows due to overload, transfer to the other inlet does NOT
occur and the current output to all outlets switches OFF. Transfer to the
other inlet will automatically occur only when the fuse malfunction is
caused by other reasons than overload.
If any fuse blows or malfunctions, the front panel indicates this situation
by turning on the 'Fuse' indicator lamp. See
Alarm Indicator Lamps
(on
page 89).
At the same time, the internal beeper turns on. See Beeper (on page
138).
To determine which fuse is blown or malfunctions, check the fuse status
in the web interface. See
Dashboard
(on page 150) or
Transfer Switch
(on page 162).
Comparison: Fuses for the inlet transfer switch protect the inlet transfer
switch from overload. Overcurrent protectors for outlets, if available,
protect associated outlets from overload. The rating of a fuse for the
inlet transfer switch is higher than the rating of an overcurrent protector
for outlets. See
Overcurrent Protectors for Outlets
(on page 137).
