Noise Path
When the signal cables are run in parallel with or bundled with the power cables, magnetic and static
induction noise may be propagated to the signal cables to effect the devices and the following measures
must be taken:
(1) Install easily affected devices as far away as possible from the power regeneration common
converter.
4) 5) 6) (2) Run easily affected signal cables as far away as possible form the power regeneration common
converter.
(3) Do not run the signal cables and power cables (power regeneration common converter I/O cables) in
parallel with each other and do not bundle them.
(4) Use shielded cables for signal cables and power cables and run them in individual metal conduits to
reduce further effects.
When the power supplies of the peripheral devices are connected to the power supply of the power
regeneration common converter within the same line, power regeneration common converter-generated
noise may flow back through the power supply cables to misoperate the devices and the following
measures must be taken:
7)
(1) Install the radio noise filter (FR-BIF) to the power cables (input cables) of the power regeneration
common converter.
(2) Install the line noise filter (FR-BLF, FR-BSF01) to the power cables (I/O cables) of the power
regeneration common converter.
When a closed loop circuit is formed by connecting the peripheral device wiring to the power regeneration
common converter, leakage current may flow through the ground cable of the power regeneration
8)
common converter to affect the device. In such a case, disconnection of the ground cable of the device
may cause the device to operate properly.

Note: 1. For installations in the United States or Canada, the circuit breaker must be inverse time or
instantaneous trip type.
2. When the breaker on the primary side of the power regeneration common converter tripped, check for
wiring fault (e.g.short circuit), damage to internal parts of the inverter (power regeneration common
converter), etc. Identify the cause of the breaker trip, then power on the breaker after removing the
cause of the trip.
