Connection Of Wiring - Fujitsu UTP-VX60A Installation Manual

7.4. Connection of wiring

7.4.1. Terminal Explanation and Cable Holes
• Only one cable can be passed through each cable hole. To pass multiple cables
through a single cable hole, use a (fi eld supply) multi-conductor cable with more wires,
and bundle multiple cables into one.
• Maximum length of cable is 10 m. (recommended value, Except "P1" and "TR1")
