Fault
Terminal does not
power up.
Possible cause
Improper connection to
power source
Incorrect input voltage
level.
DC power wires reversed
(DC terminals only).
Power terminal block not
fully seated (PV300 ter-
minals only).
Solution
r Verify wiring and connec-
tions to power source.
r Verify correct voltage is
present at power terminals.
r Make sure DC power posi-
tive and negative are con-
nected to the proper termi-
nals.
r Verify power terminal
block is snapped onto base
of PV300 Micro.
WARNING: Electrical shock hazard
Diagnosing electrical and processor problems
require access to the electrical enclosure while
power is on. Only qualified electrical technicians,
who are trained in how to avoid voltage hazards,
should perform troubleshooting procedures that
require access to the B32 Input/Output enclo-
sure while power is on.
