WARNING
Do not modify the products.
Do not also disassemble or modify the parts. It may cause a fire, electric shock or injury.
Prohibition of modification.
For spare parts, use those specified (*).
If unspecified parts are used, a fire or electric shock may be caused.
*: For details, refer to the parts list.
Use specified parts.
Before troubleshooting or repair work, do not bring a third party (a child, etc.) except the repair
engineers close to the equipment.
It causes an injury with tools or disassembled parts.
Do not bring a child
close to the equipment.
Insulating measures
Assembly/Cabling
Please inform the users so that the third party (a child, etc.) does not approach the equipment.
Connect the cut-off lead cables with crimp contact, etc, put the closed end side upward and
then apply a water-cut method, otherwise a leak or production of fire is caused at the users’
side.
After repair work, surely assemble the disassembled parts, and connect and lead the removed
cables as before. Perform the work so that the cabinet or panel does not catch the inner
cables.
If incorrect assembly or incorrect cable connection was done, a disaster such as a leak or fire is
caused at user’s side.

TCS-NET General Purpose Interface
After the work has finished, be sure to use an insulation tester set (500V mugger) to check the
resistance is 2MΩ or more between the charge section and the non-charge metal section
(Earth position).
Insulator check
Be attentive to
electric shock
Check after rerair
Check after reinstallation
If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side.
When checking the circuit inevitably under condition of the power-ON, use rubber gloves and
others not to touch to the charging section.
If touching to the charging section, an electric shock may be caused.
After repair work has finished, check there is no trouble.
If check is not executed, a fire, electric shock or injury may be caused. For a check, turn off
the power breaker.
After repair work (installation of front panel and cabinet) has finished, execute a test run to
check there is no generation of smoke or abnormal sound.
If check is not executed, a fire or an electric shock is caused. Before test run, install the front panel
and cabinet.
Check the following items after reinstallation.
1) The earth wire is correctly connected.
2) The power cord is not caught in the product.
3) There is no inclination or unsteadiness and the installation is stable.
If check is not executed, a fire, an electric shock or an injury is caused.
Service Manual
WARNING
Put on gloves
Cooling check
CAUTION
Be sure to put on gloves (*) during repair work.
If not putting on gloves, an injury may be caused with the parts, etc.
(*) Heavy gloves such as work gloves
When the power was turned on, start to work after the equipment has been sufficiently cooled.
As temperature of the compressor pipes and others became high due to cooling/heating operation, a
burn may be caused.

1. Outline
This document describes how to troubleshoot individual problems in interfacing with general-purpose devices
using the TCB-IFCG1TLE. For information on Applications/Functions/Specifications, Installation, Connection of
Power cable and Signal wires, Setting, Trial Operation Check, Connection to External Devices, and so on, see the
Installation Manual of the TCB-IFCG1TLE.
2. Required Devices and Tools
• Screw driver (for +M4 screw)
• TESTER
• DYNA KIT (for TEST 4-3)
• The setting tool software for the advanced conjunction function for the general purpose interface must be
installed on the PC (with Windows 2000, XP or later) for TEST 4-3.
3. Checking the Board inside the TCB-
IFCG1TLE
In troubleshooting procedures described in Section 4 or later, you need to check the settings, connections, and
LEDs of the board inside the case.
Disconnect the DC plug of the AC adapter, remove the screws located in the four corners of the case lid, and open
the lid of the case. Connect the DC plug again, and turn on the unit.
