HARC-MODBUS - Installation Manual
4. Installation work
When unpacking the HARC-MODBUS, check that it has not suffered damage during transport.
4.1 Dimensional
data
Caution:
- The signals’ cables should be as
short as possible. Keep a distance
of more than 150 mm from other
power cables. Don’t wire them
together (although they may
intersect). If they must necessarily
be installed together, take the
following measures to avoid noise:
- Protect the signal cable with
a metal tube which is earthed
at one end.
- For communications, use
shielded wire which is earthed
at one end.
Danger:
- Always disconnect the power
supply for HARC-MODBUS when
handling the machine, in order to
avoid eletrical discharges.
- Do not connect the interface to the
power supply until the installation
has been completed.
- Comply strictly with local security
codes and regulations when
connecting the machine to the
electric network.
- You will need a three-wire cable
(two cores and earth) with a
suitable plug at one end.
Attention:
- Before applying power and turning
on HARC-MODBUS you must
ensure that:
1. All circuits to be connected are
correctly applied.
2. All H-Link connections have
been set up.
3. Follow the local regulations
for the electrical installation
of HARC-MODBUS and
associated circuits.
Any unit that is not connected or
is not under power when turning
on HARC-MODBUS, will not be
recognised and will have to be
configured later.
4.2 Fastening
Perform the following procedure:
1 Remove the rubber supports.
2 Unscrew the 4 screws from the top cover and remove it.
3 Attach the box to the rear vertical board from the inside with M4 screws (not provided)
and place 3mm washers on the outside to separate the box from the wall.
4 Reinstall the top cover. Be careful to position it correctly.
5 Keep free grated area for ventilation and cable connection.
