Note
Ensuring the function of digital inputs
An open input is interpreted as "low".
Terminal M1 must be connected so that the digital inputs (DI) can function.
This is achieved through one of the following measures:
1. Provision of the ground reference of the digital inputs.
2. A jumper to terminal M. (Note: This removes the electrical isolation for these digital
inputs.)
