2.4 Connecting the Power Adapter
Before connecting the power adapter to your HMI-640S, you must first
attach the Power Terminal Block onto the 24 V
DC
power receptable
located beneath the HMI-640S. After the Power Terminal Block has
been attached, you can then connect the power adapter to the Power
Terminal Block to provide power supplies to your HMI-640S.
To connect the power adapter:
1. Identify each wire of the power adapter cord (you must first make
sure which is +, - or GND specifically).
2. Unscrew the screws on the power terminal. Insert each wire of the
power adapter cord specifically into its designated connector hole
(+, - and GND) on the Power Terminal Block. Fasten the screws to
secure wires in the connector holes.
Warning! Avoid shorting any bare wires since it may cause
damages to your system or device.
