ASCO 430 Surge Protective Device (SPD)
Electrical
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Confirm the surge protective device voltage rating on the module or
nameplate label is not less than the operating voltage.
Failure to follow these instructions will result in death or serious injury.
Prior to mounting the SPD, verify that the device has the same voltage
rating as the power distribution system in which it is installed. Compare the
nameplate voltage or model number on the SPD with the nameplate of the
electrical distribution equipment.
The specifier or user of the device should be familiar with the configuration
and arrangement of the power distribution system in which the SPD is to be
installed. The system configuration of any power distribution system is based
strictly on how the secondary windings of the transformer supplying the ser-
vice entrance main or load are configured. This includes whether or not the
transformer windings are referenced to earth via a grounding conductor. The
system configuration is not based on how any specific load or equipment
is connected to a particular power distribution system. See Table 1 for the
service voltage of each SPD.
