INSTALLATION
To install the device we recommend complying with the following instructions to ensure optimal commissioning of the
system.
Installation must be carried out by specialised personnel authorised to install electrically live equipment.
Mechanical installation
The device is designed exclusively for DIN rail mounting; no other forms of installation are permitted.
DIN rail mounting consists of the following steps:
•
Mount the DIN rail to the bottom of the electrical cabinet or in the position planned for installation
•
Remove all the device terminals before attaching the device to the DIN rail
•
Place the recess in the base of the device on the top of the rail, keeping the device inclined by 45° with respect
to the rail. Rotate the device until it engages with the rail.
Electrical installation
Read carefully
To avoid high levels of mechanical stress on the terminals that may damage the device, make all the necessary wiring
with the terminals disconnected from the device. Proceed as follows:
•
Extract the terminals from the device by pulling them outwards
•
Clamp the wires to the extracted terminals, observing the correct polarity
•
Refit the terminal with the wires, observing the correct position of the terminal
Before commissioning the device check the following points:
•
Make sure the electrical cabinet in which the device is installed is de-energized
•
Check for the presence of the general protection devices for the electric supplies (fuses, circuit breakers,
RCDs)
•
Make sure the electric supply voltage is in compliance with the device operating limits and that the power
supply unit power rating is sufficient to assure operation of all the devices connected to it, checking the
maximum power consumption of each device (24Vdc +/- 10%, 24Vac (min 20Vac, max 40Vac)
•
If using a PoE supply (Power Over Ethernet) make sure the network cable is connected to ETH1 and that
the PoE switch is compatible with the device
