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 HC-A32MB 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.
