Warning! Check that the installation is isolated from AC mains power
and that power cannot be reapplied during work on cables and
connections.
Warning! Before connecting devices to the output (OUT) or
throughput (THRU) connectors of a VC-Feeder™, check carefully the
information about system layouts and maximum safe limits:
• in "Safety information" on page 4 of this manual, and
• in the user manuals of the devices in the system.
Warning! When linking a VC-Feeder™ to other devices using its
throughput connector, respect the maximum limits given in display
device user manuals for the number of devices that can be linked in
a chain and maximum permitted cable lengths.
Important! Do not connect more than twenty (20) VC-Feeder™
devices in one linked chain, even if you have not reached the
maximum permitted current draw for the chain.
