The wired terminal will need to be connected to a mains power socket and not an extension cable to eliminate any potential issues which might prevent the device from working properly.

If the terminal is being connected by broadband then it will need to be located close to the router or a socket, if operating structured cabling, it will need to be directly connected via the Ethernet cable.

If connecting by a phone line then the wired card payment terminal needs to be located near to the phone line and not through extensions and preferably not through splitters. If the line is also being used for broadband then the line will need a broadband filter and the wired (corded) terminal will need to be plugged into the filter rather than directly into the socket. If this isn’t done, every time a payment is taken the broadband will become disconnected.
