3. WIRING
Wiring must be done before main power switched on to the iTDC/iTDC-SR. Wiring after main
power switched on may cause electrical shock.
3.1 EARTH GROUND WIRING [IMPORTANT]
When installing iTDC/iTDC-SR, you must connect GND wire of Power terminal block to 1
ST
class EARTH
GROUND. EARTH GROUND wiring equalizes all ground level to zero and protects the device from the thunderbolt
or surge voltage.
