3. EARTH GND CONNECTION
3.1 EARTH GND CONNECTION WHEN INSTALLING ITDC/ITDC-SR TO NEMA CASE
Please refer to a figure below for Earth GND connection (only applicable for NEMA package). GND connection will
avoid potential difference and also prevents any possible abnormal behavior caused by thunderbolt or surge.
(Figure: Earth GND connection when installing iTDC/iTDC-SR to NEMA case.)

Quick Installation Guide
No. / Name
HOW TO CONNECT EARTH GND
1. NEMA case
A NEMA case provided by IDTECK is metallic which will be suitable for the
product. Make sure to use metallic NEMA case if you are using one from a third
party.
2. Supporter
Make sure to use metallic supporters (Supporter to connect iTDC/iTDC-SR main
board to EIO88, Nema case to iTDC/iTDC-SR, and NEMA case to power supply
device).
3. Screw
When fixing the product to the NEMA case, make sure to use metallic screws.
4. Groundcontactpartof
Nemacase
Ground contact part is for connecting a plug (Earth GND) to the NEMA case.
Connect Earth wire of NFB using a metallic screw.
A circular lug must be used to tightly fix the screws.
5. Ground contact part
of power point
Make sure to use power point with Earth GND connecting piece as shown in the
figure above.
The size of IDTECK’s NEMA case is 350mm X 399mm X 100mm (Width X Depth X Height) with
thickness of 1.4mm. When using any third party NEMA Case, make sure that it is metallic
(for conductivity) and has a larger size than IDTECK’s NEMA case. Make sure to ground it firmly.
Use the ones with doors to completely isolate the product from outer environment.
Caution when using NEMA case

3.2 EARTH GND CONNECTION WHEN ITDC/ITDC-SR IS NOT INSTALLED ON NEMA CASE
When installing iTDC/iTDC-SR without a NEMA case, GND wire associated to power port of each device must be
grounded to Earth GND. GND connection will avoid potential difference and also prevents any possible abnormal
behavior caused by thunderbolt or surge. Please refer to the figure below for instruction of how to connect Earth GND.
Earth GND
(Figure: Connection of Earth ground when installing a iTDC / iTDC-SR)

Quick Installation Guide
1. When installing reader or input device on metal frame, make sure to ground the metal frame and Earth
GND firmly to prevent static electricity. Static electricity may cause abnormal behavior and shorten the
product lifetime.
2. In order to prevent interaction with an external conductive material, use insulation tape when wiring
reader, exit button, and lock. Make sure to cut cleanly to prevent exposure of cable core. Use insulation
tape to complete the wiring. Interaction of exposed cable core with conductive materials (frame) must be
avoided to prevent product damage.

communication error. Noise from outside can cause system troubles and may shorten the product lifetime. RF
reader can use external power.
5. REVERSE DIODE CONNECTION
If you connect an inductor (Door Locks or Alarm device) to the output relays, there will be a high surge voltage created
while the inductor is turning on and off. To protect this problem, connect the reverse diode as the figure below.
Caution
It is strongly recommended to add a reverse diode between the inductor coils to absorb this surge voltage.
If you do not connect a reverse diode, the surge voltage will transfer and damage the electronic circuit of the controller.
1N4004 –1N4007 or equality efficiency diode is included in gift box.

Quick Installation Guide
6. SYSTEM INITIALIZATION
Initialization must be performed before first installation of iTDC/iTDC-SR. Press down the two initialization switches
simultaneously then keep pressing more than 2 seconds. Once buzzer sound is generated, release the switches to
finish initialization. The system will restart automatically.
Figure: Position of Initialization Switches and its Magnification Figure: LCD Display
If you initialize the iTDC, all the data memories such as ID information, communication speed, door setting, time
schedule and event information stored in the controller will be cleared and the basic setting values (factory setting
values) will be reloaded. Therefore, the Initialization should be performed by authorized personnel only.
