5.1 General instructions
Information on the delivery status of your valve terminal can
be found using the product key (see Chapter A.1.1).
Warning
Uncontrolled movements of the connected actuators and
loose tubing can cause injury to persons and/or damage
to property.
Before carrying out installation and maintenance work,
switch off the following:
• Compressed air supply.
• The operating and load voltage supplies.
Note
Handle all modules and components of the MPA-S valve
terminal with great care. Note especially the following
when mounting components:
• Screws must be fitted exactly (otherwise threads will be
damaged).
• Screws must be only screwed in by hand. Screws must
be fitted so that the self-cutting threads can be used.
• The specified torques must be observed.
• Threaded connections must be mounted free of offset
and mechanical tension.
• Check the seals for damage (IP65).
• The contact surfaces must be dry and clean
(sealing effect, avoid leakage and contact errors).
