Preliminary Warnings
The following preliminary warnings should be
read before installing and using the series 450

into service more quickly and will avoid certain
problems which may mistakenly be interpreted
as malfunctions or limitations of the controller.
• Immediately after unpacking the controller, make a
note of the order code and the other identification
data given on the label affixed to the outside of the
container and copy them to the table below.
These details must always be kept close at hand and
referred to the personnel involved in the event of help
from Gefran Customer Service Assistance.

not been damaged at all during transit, and that the
package contains not only the controller and these
