USE OF Z-PC-DINAL ACCESSORY
CAUTION:
When you turn On the module for the first time, the device must be powered
without any interruptions for at least 72 hours in order to charge the internal batteries
Power off the module, using the PS1 button, before connecting the inputs and outputs.
In order to satisfy the electromagnetic compliance requirements:
- use shielded cables for the signals transmission.
- connect the shield to a preferential ground for devices.
- keep the shielded cables at a distance from other cables used for power installations.
(transformers, inverters, motors, induction ovens, etc...).
