3.1 General installation instructions
Note
Observe the following if the UL requirements are to be
complied with in your application:
Ĉ Rules for observing the UL certification can be found in
the separate UL−specific documentation. The relevant
technical specifications listed there also apply here.
Ĉ The technical specifications in this documentation may
show different values.
Warning
Uncontrolled movements of the connected actuators and
uncontrolled movements of loose tubing can cause injury
to human beings or damage to property.
Before carrying out installation and maintenance work,
switch off the following:
Ĉ Compressed air supply
Ĉ The operating and load voltage supplies.
3.1.1 Connecting cable
Field bus cable Use a suitable cable for your field bus system. Refer to the
manual for your controller for the type of cable to be used.
Also take into account here the distance and the fieldbus
baud rate.
Operating voltage cable Use a cable for the operating voltage with sufficient cross−
sectional area. Avoid long distances between the power unit
and the CPX terminal. Long operating voltage cables reduce the
voltage supplied by the power unit.
If necessary, ascertain the suitable cross−sectional area of the
cable and the maximum permitted cable length in accordance
with the general rule in section A.2.
