3. Disassembly and assembly of the battery case MR-
BT6VCASE
(1) Disassembly of the case
MR-BT6VCASE is shipped assembled. To mount MR-BAT6V1
batteries, the case needs to be disassembled.
Screw
Remove the two screws using a Phillips
screwdriver.
Cover
Remove the cover.
(2) Mounting MR-BAT6V1
BAT1
Securely mount a MR-BAT6V1 to the BAT1
holder.
CON1
Click
Insert the MR-BAT6V1 connector mounted
on BAT1 holder to CON1.
Confirm the click sound at this point.
The connector has to be connected in the
right direction.
If the connector is pushed forcefully in the
incorrect direction, the connector will break.
Place the MR-BAT6V1 lead wire to the duct
designed to store lead wires.
Insert MR-BAT6V1 to the holder in the same
procedure in the order from BAT2 to BAT5.
Bring out the lead wire from the space between the ribs, and bend it as
shown above to store it in the duct. Connect the lead wire to the
connector. Be careful not to get the lead wire caught in the case or
other parts.
When the lead wire is damaged, external short circuit may occur, and
the battery can become hot.
(3) Assembly of the case
After all MR-BAT6V1 batteries are mounted, fit the cover and
insert screws into the two holes and tighten them. Tightening
torque is 0.71 N•m (6.284 lb•in).
Screw
POINT
When assembling the case, be careful not
to get the lead wires caught in the fitting
parts or the screwing parts.
(4) Precautions for removal of battery
The connector attached to the MR-BAT6V1 battery has the lock
release lever. When removing the connector, pull out the
connector while pressing the lock release lever.
4. Battery transportation
When only lithium metal batteries are transported, attachment of a
handling label to each package, submission of the Shipper's
Declaration for Dangerous Goods, and a 1.2 m drop test will be
required. When the batteries are transported with mounted on
products, the regulations about package, etc. will not be required.
CAUTION
Do not use this battery case for encoders which
have super capacitor.
