5. If the equipment is used in a manner not specified by the manufacturer, the protection provided by
the equipment may be impaired.
6. Equipment installation
6.1 The control unit and the peripheral units have been designed on the assumption that they arehoused in closed cabinets. The cabinet should basically be made of metal.
6.2 Set up the LCD-mounted type control unit, the display unit, and the MDI unit on a flat surface ofa Type 1 Enclosure.
6.3 Installing the LCD-mounted type control unit
Air is fed into the control unit from the bottom, drawn by the fan motors which are located on thetop of the control unit.
Space ○
A , shown in the figure below, must be provided to ensure unrestricted air flow. Also, space
B should be provided whenever possible. When space ○B cannot be provided, ensure that○
nothing is placed in the immediate vicinity which could obstruct the air flow.

6.4 Installing the Stand-alone type control unit
Air is fed into the control unit from the bottom, drawn by the fan motors which are located on the
top of the control unit. The spaces shown in the figure below (areas ○A and ○B ) must be provided
to ensure smooth air flow.
Also, adequate service access space is required in front of and at the top of the unit so that printed
circuit boards and the fan motor can be replaced easily if necessary.
There is a spare connector located at the far end (at middle height) on the right side of the control
unit. This connector is used for control unit testing and other purposes. Therefore, space (areaC ) for handling the connector is required.

For Stand-alone type control unit
Prepare a new lithium battery (ordering code: A02B-0200-K102).
1) Turn the power to the machine (control unit) on. After about 30 seconds, turn the power off.
2) Remove the lithium battery on the upper section of the control unit.
First, unplug the connector by yanking the battery cable, and then take the battery out of its
case.
The battery case is located in the upper section of the face plate of the main board.
3) Insert a new lithium battery and reconnect the connector.

WARNING
Using other than the recommended lithium battery may result in the battery exploding.
Replace the battery only with the specified lithium battery (A02B-0200-K102).

7.3. Replacing FAN motors
For LCD-mounted type control unit
1) When replacing the fan motor, be sure to turn off the power to the control unit.
2) Remove the fan motor from the case by holding fan motor’s latch and pulling it out while
releasing the claw from the case.
3) Put the fan motor into the case. After that, make sure that the fan motor’s claw has latched
the case securely.
To remove the fan motor, hold the latches ofthe fan motor and pull it out.

5. Pull out the fan unit toward youin the slanted direction.

Attaching a fan unit
1) Insert a fan unit deeply into the control unit at a slanted angle of about 30 degrees so that thefan unit touches the wall of the control unit.
2) Lower the fan unit slowly on the control unit.
3) Push down the fan unit onto the near side to couple the fan unit with the top of the controlunit.

1. Insert the fan unit at about 30
degrees until it touches thefar-side wall of the main unit.

2. Lower the fan unit slowly.

3. Push down the fan unit toconnect it to the main unit.

CAUTION
The fan unit and main board are coupled directly with each other by the connector. Whenmounting the fan unit, failing to follow the connection procedure correctly may damage
the coupling part of the connector.

4. Push down the latch

Unlatched

Latched5) Turn on the power, then check that no fan alarm is issued and that both fans are rotating.
CAUTION
