SCR Firing Test
In normal operation, the SCR firing cards derive their power from a voltage
divider network that steps down the medium voltage to 20V DC maximum. As it
is necessary to perform this test while isolated from medium voltage, you need a
secondary power source for firing cards.
ATTENTION: Ensure that the drive is no longer running in test mode prior to
applying medium voltage to the drive line-up. Failure to do so may result in
equipment damage.
