Surge Protector
The FLEXware Surge Protector is designed to protect the FLEXpower ONE’s sensitive components
from excessively high voltages (e.g., electrical storms). Thermally-fused metal oxide varistors (MOVs)
limit (“clamp”) these voltages and transfer the resulting current to a lower-voltage
port. The FLEXware Surge Protector features ACTIVE and ERROR LEDs for the DC, AC
IN, and AC OUT circuits. The Surge Protector is located in the FLEXpower ONE’s AC
wiring compartment.
The FLEXware Surge Protector shunts
excess current from:
 DC+ (to
GROUND )
 AC HOT IN (to GROUND)
 AC NEUTRAL IN
(to GROUND)
 AC HOT OUT
(to AC
NEUTRAL OUT)
 AC HOT OUT (to GROUND)
 AC NEUTRAL OUT (to GROUND)
LEDs
 ACTIVE LEDs are yellow. If these LEDs are on, power is present in that circuit.
It is normal for these LEDs to be on.
 ERROR LEDs are red. A red ERROR light indicates a problem. The LED means a
significant surge has damaged the FLEXware Surge Protector, and protection
in that circuit is compromised. Although decreased protection remains, it is
recommended that the FLEXware Surge Protector be replaced at this time,
before further damage occurs. Further damage to the Surge Protector will
eventually lead to damage to other FLEXpower ONE components.
 For an ERROR LED to turn on, its circuit must be powered; its ACTIVE LED will
also glow. Note that if the circuit is not powered, the ERROR LED will not
indicate a problem even if one is present.

Replacement Boards
Replacement boards for the Surge Protector are available in the event that a power surge damages
the one currently installed. To obtain a replacement board, contact your local OutBack dealer. The
OutBack designation for a replacement board is FW-SP-FP1.
