Sleep mode

The purpose of Sleep Mode is to lower the current the WSU takes from the battery when not charging.
If the WSU is connected to a small capacity battery, or if charging does not occur frequently, this current
If Sleep Mode is not used the WSU will typically draw an average of 70 mA (24 V version) or 40 mA (48
V version) from the battery. Sleep mode would reduce this to approximately 2 mA.
A high voltage level presented between pin 2 ("Sleep") and pin 3 ("EXT_Signal_GND") of the connector
instructs the WSU to enter Sleep Mode. Conversely, a low voltage level will deactivate Sleep Mode. A
should be less than 0.3 V or NC (not connected). It will take the WSU less than one second to change
mode as instructed by the Sleep signal.
The use of Sleep is optional, and if it is not require this pin can be left unconnected.
When Sleep Mode is active, charging cannot take place and CAN bus communication with the WSU is
not possible. Sleep must only be activated when the WSU is in Standby
in appendix section 9.2 shows the correct sequence of events.
