Power Supply
Not all configurations and device contexts require the use of a power supply –
Verifone ships power supply with the terminal as required.
Contact your Verifone representative if you have changed the context in which the
terminal is used or have questions about which power supply should be used.
Disconnect the power pack cord from the power outlet before connecting a power
supply. Connect and route all cables between the terminal, ECR and PC before
plugging the power pack cord into a wall outlet or surge protector.

Insert the card with the card’s gold contacts facing away from you, towards the

Do not plug the power pack into an outdoor outlet or operate the terminal
outdoors. Disconnecting power during a transaction can cause transaction data
files not yet stored in memory to be lost.

possible damage caused by lightning strikes and electrical surges.
