MEASUREMENTS AND INSTALLATION
Measurements
Measurements are expressed in mm (inches).
IMPORTANT
Read this document carefully before installation and before using the device and take all the prescribed precautions. Keep this document with the device for future consultation.
Only use the device in the ways described in this document.
Do not use the device as safety device.
For more information see the installer manual.
The device must be disposed of according to local regulations governing the collection of electrical and electronic waste.
1.2 Installation
To be installed on a panel with snap-in brackets.
2.2 Description of connectors
INSTALLATION PRECAUTIONS
- The thickness of the panel on which the device is to be installed must be between 0.8 and 2.0mm (0.031 and 0.078 in).
- Ensure that the working conditions for the device
(operating temperatures, humidity, etc.) are within the set limits. See the section TECHNICAL
SPECIFICATIONS.
-
-
Do not install the device close to heat sources
(heating elements, hot air ducts, etc.), equipment with a strong magnetic field (large diffusers, etc.), in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations or shocks.
In compliance with safety regulations, the device must be installed properly to ensure adequate protection from contact with electrical parts. All protective parts must be fixed in such a way as to need the aid of a tool to remove them.

PRECAUTIONS FOR ELECTRICAL CONNECTION
- Do not use electric or pneumatic screwdrivers on the
- terminal blocks of the device.
If the device has 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 are within the set limits. See the section TECHNICAL SPECIFICATIONS.
Disconnect the device 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 phasecutting command signal.
If using triac digital outputs, we recommend
-
- connecting a noise filter; do not touch the heat dissipator because it could be very hot
Connect the device to an RS-485 network using a screened twisted pair. We recommend using a
BELDEN 3106A cable.
Connect the power cables as far away as possible from those for the signal.
- For repairs and for further information on the device, contact the EVCO sales network.
