If the machine is equipped with monitoring devices or sensors:
• Make sure that the monitoring devices are correctly connected and integrated into
a control system such that operation of the machine will be inhibited if the safety
limit values are exceeded, see Electrical Connection of the Monitoring Devices
[►14].
5.2 Connecting Lines / Pipes
• Remove all protective caps before installation.
• Make sure that the connection lines cause no stress on the machine‘s connection; if
necessary use flexible joints.
• Make sure that the line size of the connection lines over the entire length is at least as
large as the connections of the machine.
In case of very long connection lines it is advisable to use larger line sizes in order to
avoid a loss of efficiency. Seek advice from your Busch representative.
