1.2 Circuit board removal and installation
Removal:
1. Switch off operating voltage.
CAUTION
If the operating voltage is not switched off, product and
system can be damaged.
2. Remove terminal strip (2) from plug connector (3).
3. Remove screws (1 + 4).
4. Carefully pull board out of the rack without tilting.
Installation:
1. Carefully insert board into rack, guiding slot without
tilting.
2. Tighten screws (1 + 4) so that the cooling attachment
on the board contacts the metal rack and thus ensures
optimum heat dissipation.
NOTE
Do not exceed permissible tightening torque to avoid
board damage.
3. Make sure that operating voltage is switched off.
CAUTION
If the operating voltage is not switched off, product and
system can be damaged.
4. Introduce terminal strip (2) into plug connector (3).
CAUTION
Contacts must not be damaged, otherwise perfect func-
tioning of the system is not ensured.
