Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in
performance when subjected to the rradio frequency (RF) environments defined in the following table:
Test
Electrostatic discharge
Radiated RF immunity
Electrical fast transient
Surge immunity
Conducted RF immunity
Power Frequency H-field
immunity
Voltage dips, interrupts
A -
1) No upset or degradation in performance beyond manufacturer's specified limits.
2) No data loss.
B -
1) Unit self recovers without user intervention.
2) No data loss.
C -
1) Upset OK provided that unit will function after user intervention.
