WARNING
ONLY QUALIFIED PERSONNEL/ELECTRICAN SHOULD INSTALL OR SERVICE SURGE SAFE™
DEVICES.
ELECTRICAL SAFETY PRE-CAUTIONS MUST BE FOLLOWED WHEN INSTALLING OR SERVICING
THIS EQUIPMENT.
TO PREVENT RISK OF FIRE, ELECTRICAL SHOCK, OR DEATH; ALL POWER SOURCES TO THE
UNIT MUST BE TURN OFF AND LOCK OUT BEFORE MAKING ELECTRICAL CONNECTIONS OR
SERVICING.
SURGE SAFE™ DEVICES ARE NOT TO BE USED WITH A HI-LEG DELTA VOLTAGE
CONFIGURATION.
THIS SPD MAY NOT SURVIVE SUSTAINED OVERVOLTAGES.
Caution
– Ungrounded power systems are inherently unstable and can produce excessively high line to ground voltages
during certain fault conditions. During these fault conditions any electrical equipment, including an SPD, may be subjected to
voltages which exceed their designated ratings. This information is being provided to the user so that an informed decision can
be made installing any electrical equipment on an ungrounded power system.
Verify the system voltage and wiring configuration is the same as the enclosed
Surge Safe™ by checking it
against the product label.
