Connection
■
Power input connection
Connect the positive (+) side of the power source to
the red screw side of the terminal block on the back
of the TM700, and its negative (-) side to the black
screw side. The input voltage is 24V DC(±15%).
■
Protective ground connection
The grounding terminal is for prevention of electric shocks.
Use an approx. 0.75mm
2
thick wire, and be sure to ground.
1.
Make sure that no power is applied.
2.
Remove the screws(M4) at the protective ground.
3.
Align the solderless terminals(M4) with the screw
holes, and then tighten the screws.
WARNING
- Connect with no power applied because it may cause an electric shock.
- Since the TM700 has no power switch, install a breaker.
- Be sure to ground the protective ground terminal to prevent electric shocks.
Do not use other screws than that attached to the main body.
