The STS will safely withstand without mis-operation or damage:
• Transient voltage surges on either AC power input as defined by ANSI/IEEE C62.41 for Category B3
locations (high surge exposure industrial and commercial facilities)
• Electrostatic discharges (ESD) up to 10 kV at any point on the exterior of the unit
• Electromagnetic fields from portable transmitters within 3 feet (1 meter) of the unit
Grounding for the WaveStar Static Transfer Switch must comply with local building codes and National Electric
Codes.
