 When not using the Remote Control function, use it with either the RC terminal open or connected to the –Vin terminal.
 When not using the Alarm function, use it with the ALM terminal in an open condition.
 Use the PO terminal for controling multiple unit operation (series, parallel operation etc.).
For single unit operation, use the PO terminal in an open condition.
 The converter is to be operated exclusively on DC input. Use of AC input will cause damage.
