Before using the device, make sure to read these safety precautions and instruction manual thoroughly. The cautionary items
noted herein are of the utmost importance for the safe use of this device, and should always be strictly followed.
Make sure that the final user receives this manual.
This instruction manual is prepared for an electrical expert.
The following symbols have been used:
DANGER
DANGER
Do not use the device on the conditions over range. Failure to do so may result in fire.
Do not touch the terminals. There is a risk of electrical shock.
CAUTION
Failure to follow these instructions
may result in dangerous conditions,
which in turn could lead to severe
personal injury or even death.
Failure to follow these instructions
may result in dangerous conditions,
which could result in moderate to
slight personal injury or damage to
equipment and facilities
This means prohibition. Never ignore
this indication.
Make sure to follow these
instructions without fail.
CAUTION
A qualified electrician should install this equipment.
Make sure to tighten the terminal screws to the torque specified in this manual. Failure to do so may result in malfunction
or fire.
Do not install in areas subject to high temperatures, high humidity, dust, corrosive gas, vibrations, shocks, etc. To do so
may result in malfunction or fire.

■EMC Directive
In IEC60947-2, following EMC tests are required.
1) Radiated radio frequency emission
2) Radiated radio frequency electromagnetic field immunity
BIF-CC is confirmed to IEC60947-2 in accordance with following conditions.
1) BIF-CC shall be installed in the panel board. It effects not only for safe against electric shock but also to interrupt
noise emission from the device.
2) When attaching the panel's top plate or base plate, mask painting and weld so that good surface contact can be
made between the panel and plate.
3) To ensure good electrical contact with the panel board, mask the paint on the installation bolts of the inner plate
in the panel board so that contact between surfaces can be ensured over the widest possible area.
4) Earth the panel board with a thick wire so that a low impedance connection to ground can be ensured even at high
frequencies (*ground resistance: 100 ohm or less).
5) Provide an earthing point near the BIF-CC. Earth the FG terminal of BIF-CC with the thickest and shortest wire
possible (*ground resistance: 100 ohm or less). The FG terminal function is to pass the noise generated in the
BIF-CC or the noise from outside to the ground, so an impedance that is as low as possible must be ensured.
Also, in case that the CC-Link cable is extracted to the outside of the panel board, earth it at point close to the
exit of panel board. An appropriate installation has the effect of suppressing the generation of the
electromagnetic induction and the high frequency noise.
6) If the measure described above does not provide sufficient shielding effects, fit ferrite cores to the power supply
line of BIF-CC. We recommend ferrite core made by TDK (type: ZCAT2032-0930). For CC-Link cables, however,
do not use ferrite cores.
7) CC-Link cable, Internal transmission cable and BIF-CON cable shall be kept distance more than 100mm from the
power distribution circuit. However, when parallel installation with the power distribution circuit is required, it is
necessary to increase to 300mm.
■Dielectric voltage test
The dielectric voltage test should be executed according to the table below. Do not test in points other than a
following table because unit is damaged.

When a setting of alarm holding method is “Self-Holding”,
the alarm information (last 10 alarms) except for PAL1 P.U.,
PAL2 P.U. and OVER can be stored in the EEPROM.
On the other hand, when a setting of alarm holding method is
“Auto Reset”, any alarm information are not stored.
Also, when Power supply module (P1-P5) is off, any alarm
information are not stored.

Alarm holding method
-
Set the alarm holding method.
When a setting of alarm holding method is “auto reset”,
the active alarm status will return to normal state automatically
if load current falls below the pickup level. On the other hand,
when a setting of alarm holding method is “self-holding”,
the alarm status will remain until it is reset by reset order even
if load current falls below the pickup level.
However, PAL1 P.U., PAL2 P.U., OVER and TAL are always
returned to normal state automatically whether “auto reset”
or “self-holding”.
