INSTALLATION
Carefully follow these instructions to install the device, in order to be able to commission the system in the
best possible way. The device must be installed by qualified personnel, specialised in the installation of electrical
equipment.
5.1
Mechanical assembly
This device has been designed to be DIN-rail mounted; therefore, no other mounting options are allowed. The
DIN-rail mount consists of the following steps:
•
Fasten the DIN rail to the bottom of the electrical panel (if it is not already provided with it)
•
Remove all the terminals of the device before hooking it on the DIN rail
•
Place the recess at the bottom of the device on the upper part of the DIN rail, keeping it at a 45° angle
with the rail. Turn the device until it engages with the rail.
Carefully read the following notes
To prevent mechanical stress on the terminals, which could damage the device, it is important to wire the terminals
disconnected from the device. Follow these instructions:
•
Remove the terminals from the device pulling outwards
•
Tighten the cables to the removed terminal complying with the right polarity
•
Reinsert the terminal with the cables placing it in its correct position
5.2
Electrical installation
Verify the following before commissioning the device:
•
Ensure that the electrical panel where the device is installed is powered off
•
Verify the presence of power supply protection devices (fuses, circuit breakers, differential switches)
•
Ensure that the supply voltage is within the operating limits of the device and that the supply power
is enough to ensure the proper operation of all the devices connected to it, verifying the maximum
power consumption of each one of them
•
If you opt for a PoE (Power Over Ethernet), ensure that the network cable is connected to Eth1 and
that the PoE switch is suitable for the device.
•
Ensure that the LC is connected properly to the M-Bus network and to the supply voltage (refer to the
installation manual)
•
Ensure that the RTU is connected properly to the LC via the serial bus marked A-B-C
•
Ensure that the modem router (if any) is installed according to the instructions of the manual
•
In the event of data connection, ensure that the Ethernet cable is crimped properly and connected to
Eth1 or Eth2
