10.8 Mechanical removal of the system housing
Voltage on the pins of the “DPx” drive power
connector can be higher than 60V DC. When the
connector is unplugged a high voltage can
remain present on the pins for 5 minutes after
disconnection. If a drive slot has an
accompanying capacitor installed and the drive
module is not installed in that drive slot, you
must wait 30 minutes.
DANGER
Do not touch the pins of this connector.
Do not touch the rear side of the backplane.
Make sure that all power supplies are switched off and capacitors in the system
are fully discharged before you remove the system housing.
First, disconnect all drive power supply connectors (“DP” and “DP NY4130”).
Then disconnect the "24V System" power supply connector. Finally, disconnect
all remaining connectors and protective earth connections.
Remove the screws that mount the system housing on the metal surface in the
machine.
