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.
