3. Insert the slide-in module in the enclosure. The following steps
require a team effort:
a) Take the slide-in module on both sides from below.
b) Lift the slide-in module to the height of the enclosure.
c) Place the slide-in module in the enclosure so that the module
sits in the enclosure by approximately 25 cm.
d) Push the slide-in module onto the rails and into the enclosure
until the slide-in module sits completely in the enclosure.

4. To facilitate tightening the slide-in module in the enclosure, pull out
the module approximately 5 mm.
5. With the screwdriver, move each captive screw back and forth while
pressing inward until the screw slips into the thread.
6. Push the slide-in module back into the enclosure as far as it goes in.
7. Gradually and evenly, tighten the four captive screws on the slide-in
module hand-tight.
NOTICE
• Verify that the screws are tightened. Pull the slide-in module by the
leak tray towards the front and check whether the screws move. If
they do not move, the slide-in module is installed properly.
• If the screws move, tighten the screws further. With a torque
wrench, the recommended torque is 1.2 Nm.
8. Set up and restart the device.
