4.5 Precautions for electrical connection
- Do not use electric or pneumatic screwdrivers on the terminal blocks of the devices.
- If the devices have been moved from a cold to a warm place, the humidity may cause condensation to form inside. Wait
about an hour before switching on the power.
- Make sure that the supply voltage, electrical frequency and power of the devices correspond to the local power supply. See
the section TECHNICAL SPECIFICATIONS.
- Disconnect the devices from the power supply before doing any type of maintenance.
- The devices must be fed by power of the same phase as that feeding any module with a phase-cutting command signal.
- If using triac digital outputs, we recommend connecting a noise filter. The heat sink might reach very high temperatures,
do not touch it.
- Connect the devices to an RS-485 network using a screened cable with twisted pair for the signal and a third separate
conductor for the reference (for example the BELDEN 3106A cable). NB: do not connect the cable shield to the reference
(GND)
- Connect the power cables as far away as possible from those for the signal.
- Do not use the devices as safety devices.
- For repairs and for further information on the devices, contact the EVCO sales network.
