Leaving the plastic on can make the display hard to read due to reflections.

Powering the MASSO Touch

The power connector is located at the top-right corner of the controller.
Required power supply:
- 24 VDC nominal
- Minimum 1.5 A output
- Voltage must not exceed 25 VDC or drop below 23 VDC

Once power is connected, MASSO Touch powers on instantly.

WARNING: A 1 amp fuse must be installed between the power supply and MASSO. This protects the controller from accidental short circuits on the auxiliary power terminals. Failure to do so can cause irreparable damage.

WARNING: Only use a nominal 24 VDC power supply (23–25 VDC range).

Information

Multiple Power (Red) and Ground (Black) terminals are provided for easy wiring.

Examples:

- Power terminals can supply voltage to sensors or homing switches.

- Ground terminals can be used to create a common ground for stepper or servo drives.

CAUTION: The total current draw must not exceed 500 mA across all auxiliary terminals. Connecting high-current loads can damage the controller beyond repair .
