Always use equivalent metals for the materials. Never use aluminum (danger
of oxidation).
Connect all doors and metal parts (sides, back and cover) of the cabinet at least
three times to the cabinet frame (short, paint-free, large-area connections).
Note
If your system generates high electrostatic voltages (for example, textile ma-
chines and special construction machines), run the grounding lines of the
machine parts with interference signals to a separate operating ground iso-
lated from the central grounding point of the cabinet (surface grounding with
housing construction, reinforcement).
15.2 Assigning the Terminal Block
Connect the power supply to the terminal block on the bottom of the housing
and wire up the authorization input.
Figure 15-1 shows the assignment of the 3-pin terminal block for the
OP5/A2, figure 15-2 shows the assignment of the 4-pin terminal block for the
OP5/A1 and all OP15 versions.
