Grounding
WARNING
Use the protective earth conductors whose minimum size of the cross-sectional area is 0.75 mm
2
.
For CSA compliance (Type: -AD), use ones with cross-section area of 0.75 mm
2
to 2.1 mm
2
.
CAUTION
Connect PG400 to ground (Class D ground: 100 ohm or less) for interference avoidance and
safety reasons.
Use ground cables with larger cross - sectional area. Connect the ground cable to the internal/
external grounding terminal. (Figure 5) Use ring terminals for wiring terminals.

Wiring to output terminal
The type of oscillator cables to connect to output terminals or shield terminals varies depending
on the instrument to connect.
l
-PU (Connect to PH8HS, PH8HF)
Wire the oscillator cable to terminal U1, U2, and S. Oscillator cables are supplied to PH8HS or
PH8HF with ultrasonic cleaning specified. The terminal U3 is not used.
l
-TU (Connect to TB810D, TB820D/TB700G, TB750G)
When connecting to TB810D or TB820D, wire the oscillator cable to terminal U1, U2 and S. You
need to purchase the oscillator cable separately.
When connecting to TB700G or TB750G, wire the oscillator cable to terminal U1, U2, U3 and
S.You can continue to use the existing oscillator cables.
To connect to TB810D- with -ST, or for its replacement, use the cable as shown in note *4 on
“Model and Suffix Codes” table.
3. Operation
After every wiring completes and the cover is installed, turn on the power and confirm the green
POWER LED is lit. To start the cleaning, turn on the output switch inside the instrument and
confirm the red OUTPUT LED is lit. Make an adjustment of ultrasonic power then shut the front
cover.
WARNING
To avoid electric shock, do not insert thin or flexible wires or the like from the opening of the
instrument.
