C A U T I O N
Before switching on and starting PSC-A160WEB1 you should make sure that:
• All the units and refrigerant circuits are powered on and are working correctly.
• All the H-Link connections have been set up.
• All the units are Packaged units. Mixed connection of Packaged units and water chillers is not permitted.
Any unit that is not connected or is not powered on when turning on PSC-A160WEB1, will not be recognised and will have to be configured
later.
The signal cables should be a short as possible. Keep other power cables at a distance of at least 150 mm. Do not bind 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 metallic tube earthed at one end.
• For communications, use a shielded cable earthed at one end.
If the equipment is installed vertically, situate the power feed below and the control outputs above.
D A N G E R
• Always disconnect the power from PSC-A160WEB1 when handling the equipment to prevent electrocution.
• 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 electricity grid.
• A three-wire cable is needed for a connection to the electrical transmission network (two wires plus earth), with
a suitable plug at one end.
