Precautions
J
GENERAL PRECAUTIONS
Be careful when touching the B7AP-S1 Power Coupler during
operation because the surface temperature of the B7AP-S1
Power Coupler will rise approximately 20C after the B7AP-S1
Power Coupler starts power transmission. The surface
temperature varies with the load of the sensing device connected
to the B7AP-M1 Power Coupler and the transmission distance.
J
HANDLING
Use the B7AP-S1 and B7AP-M1 Power Couplers with the
available B7A Link Terminals. Refer to page 2, B7A Models.
The M7E-12jj Display Unit, M7E-20jj Display Unit, and B7A
Link Terminals with an I/O delay of 3 ms cannot be used with the
B7AP-S1 or B7AP-M1 Power Coupler.
Use the LOAD-OFF model for the B7A Output Unit to be
connected to the B7AP-S1. When using a model that allows
selection of error processing, set to the LOAD-OFF mode. This
turns OFF signals right before an occurrence of a transmission
error and prevents unexpected signal transmission when the
transmission error is cleared.
Separate the Power Couplers 81.5 mm min. away from each
other. The distance between the Power Couplers on standby
must be 30 mm or more.
30 mm min.
Do not supply power to the B7AP-S1 or B7AP-M1 Power Coupler
while connecting the Power Couplers to the B7A Link Terminals.
Connect the Power Couplers to the B7A Link Terminals correctly,
otherwise the internal circuits of the Power Couplers may be
damaged.
The SIG terminal must not contact with the power supply
terminals, otherwise the internal elements may be damaged and
normal transmission may not be possible.

Wire the cables of the B7AP-S1 and B7AP-M1 Power Couplers
through independent metal conduits to prevent the Power
Couplers from being influenced by noise if there are power or
high-tension lines nearby. Test the Power Couplers and make
sure that the Power Couplers operate normally before they are
put in actual operation.

Do not subject the head of the B7AP-S1 or B7AP-M1 Power
Coupler to excessive shock with hard objects.
Do not use the B7AP-S1 or B7AP-M1 Power Coupler outdoors
unless it is properly protected.
The B7AP-S1 and B7AP-M1 Power Couplers are products
meeting the requirements of IP67. The B7AP-S1 or B7AP-M1
Power Coupler cannot be, however, used in water or oil.
Keep the heads of the B7AP-S1 and B7AP-M1 Power Couplers
free from dust, otherwise improper signal or power transmission
may result between the Power Couplers.
J
MOUNTING
Use nuts and serrated toothed washers and tighten the nuts to
mount the B7AP-S1 and B7AP-M1 Power Couplers. The
tightening torque applied to each of the nuts must be 39 N S m
(28.7 ft S lbf) maximum. The mounting position will change and
improper signal or power transmission may result between the
Power Couplers if the nuts are not tightened properly.
39 NSm (28.7 ft S lbf) max.

J
TRANSMISSION DISTANCE FOR
STABLE SIGNAL AND POWER TRANS-
MISSION
The B7AP-S1 Power Coupler has a gauge that is used to adjust
the transmission distance between the B7AP-S1 and B7AP-M1
Power Couplers. Use the gauge to adjust the transmission
distance to 8 mm, make sure that the green operation indicator of
the B7AP-M1 Power Coupler is lit, and the B7A Output Unit has
no error output before operating the Power Couplers.

J
MONITORING TRANSMISSION STATUS
Judge from the power supply/error indicator and error output of
the B7A Output Unit whether the B7AP-S1 and B7AP-M1 Power
Couplers are facing each other correctly.
The error output of the B7A Output Unit will be ON when the
B7AP-S1 and B7AP-M1 Power Couplers are not facing each
other correctly.
J
MINIMUM DISTANCE BETWEEN POWER
COUPLERS MOUNTED IN PARALLEL
When mounting the B7AP-S1 and B7AP-M1 Power Couplers in
parallel, refer to the following table. Keep at least the specified
minimum distance between adjacent Power Couplers for proper
heat radiation by considering the temperature rise (approximately
20C) of the B7AP-S1 Power Couplers in operation.

EFFECTS OF SURROUNDING METAL
The B7AP Power Coupler may malfunction when affected by
surrounding metal. When mounting the B7AP within a metal
panel, ensure that the clearances given in the following table are
maintained. Be sure to check in advance that the B7AP operates
correctly.

MAINTENANCE
Regularly check these items for the stable operation of the
B7AP-S1 and B7AP-M1 Power Couplers:
The mounting positions and the tightening of the mounting
nuts.
The tightening, contacts, and breaking of the lead wires.
Dust accumulation on the heads.
The ambient operating temperature and other operating
conditions.
The transmission distance.
