VICE CO., Ltd.
Internal Circuitry of the Power Supply Tap
Remove fuse A when disconnecting cables on side A, and fuse B when disconnecting cables
on side B.
Dual Power Supply
Power Supply Taps can be used to construct a dual power supply system in the network
because diodes are built-in. Dual power supply differs from parallel operation of power sup-
plies, so the following restrictions apply.
Restrictions
Dual power supply is basically used to ensure backup power supply, not parallel operation of
power supplies. Therefore, each power supply to be used must meet the power allocation
specifications (must satisfy Steps 1 and 2).
