Qualified to IEEE C37.90.1-1989, Standard Surge Withstand Capability (SWC) Tests for Protective
Relays and Relay Systems. The RS-232 Serial Communication Port is intended only for periodic use and
is not subject to the requirements of IEEE C37.90.1.
Surge Withstand Capability—Oscillatory and Fast Transient
Type tested using a 5 W, hand-held transceiver in the ranges of 144 and 440 MHz with the antenna
placed within 6 inches (152 millimeters) of the relay.
Radio Frequency Interference (RFI)
In standard tests, the relay has withstood 15 G in each of three mutually perpendicular planes without
structural damage or degradation of performance.
Shock
In standard tests, the relay has withstood 2 G in each of three mutually perpendicular planes, swept over
the range of 10 to 500 Hz for six sweeps, 15 minutes each sweep, without structural damage or
degradation of performance.
