8.3.2.7 Installation procedure
C A U T I O N
Before applying power and turning on PC-A1IO you must ensure that:
•
All circuits to be connected are correctly applied.
•
All H-Link connections have been set up.
•
Follow the local regulations for the electrical installation of PC-A1IO and associated circuits.
Any unit that is not connected or is not under power when turning on PC-A1IO, will not be recognised and will have to be configured
later.
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 to-
gether (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.
D A N G E R
•
Always disconnect the power supply for PC-A1IO 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.
