Turning Off Power - Webasto 900 EX Installation, Operation And Maintenance Manual

4.10 TURNING OFF POWER

To shut down the 900 EX at any time, press the OFF switch or depress the
Emergency Off button (both on the AC Inverter front panel). However, in the
event of a normal, non-emergency shutdown, it is recommended that the DC
Converter be placed in Standby Mode (HMI "STOP" button) before turning off the
control power.
Once the power has been turned off, leave the Main Power switch Off (the RED
light is illuminated) and/or the Emergency Off button depressed until all indicator
lights on the front panel turn off. This allows the high voltage within the system to
dissipate (through a bleed resistor) so that the system will be safe for maintenance.
When in remote operation, the DC Converter uses
a time-out timer to monitor the Remote Operation
Interface for loss of communication.
When the DC Converter is placed in remote operation,
it waits to activate the time-out timer until the first
message has been received from the ROS.
