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.
When the terminal has power and an application is loaded, the application starts
after the initial Verifone copyright screen and displays a unique copyright screen.
If no application is loaded, DOWNLOAD NEEDED appears on the display after
the initial Verifone copyright screen.
USB Power Supply
P400 can be powered with 5 V supply from USB port (5 V at 500 mA) with the
following power-saving conditions controlled by the OS:
• Maximum audio output volume is reduced.
• LCD backlight intensity is reduced to 30% (not suitable for high-glare, outdoor
usage).
• Keypad backlight is disabled.
• Ethernet functionality is unavailable.
• BT/Wi-Fi functions are unavailable.
• The maximum USB cable length supported is 4.1 m (CBL280-025-02-A)
• In CTLS payment mode, the micro-processor operating frequency is reduced
to 300 MHz until the PINpad exits CTLS mode.
Using an incorrectly rated power supply can damage the unit or cause it not to
work properly. Use only a power pack with VPN
PWR435-001-01-A (see Service
and Support for detailed power supply specifications).
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.
Verifone recommends installing a power surge protector to protect against
possible damage caused by lightning strikes and electrical surges.
