3 Installation
Stored charge
The drive contains capacitors that remain charged to a
potentially lethal voltage after the AC and / or DC power
supply has been disconnected. If the drive has been
energized, the power supply must be isolated at least ten
WARNING
minutes before work may continue.
Normally, the capacitors are discharged by an internal
resistor. Under certain, unusual fault conditions, it is possible
that the capacitors may fail to discharge, or be prevented
from being discharged by a voltage applied to the output
terminals. If the drive has failed in a manner that causes the
Qty
display to go blank immediately, it is possible the capacitors
will not be discharged. In this case, consult Control
Techniques or their authorized distributor.
