Module Disassembly
To separate modules, reverse the procedure in Module
Assembly on page 24. When separating modules, gently rock
and pull the modules apart.
ç
CAUTION! To avoid damaging your PPC system, never connect
or disconnect modules that are powered.
Mounting Modules
Once the modules have been assembled, the PPC system may
be mounted on a DIN rail or fastened directly to a vertical
surface inside an electrical cabinet or other enclosure that
requires a key or tool to open, or that has a safety interlock
system. Consult Table 7.2 on page 230 and Figure 7.1 on page
230 to determine mounting hole spacing and installed
clearances. See Figure 1.1 on page 4 for a sample configuration
of PPC system hardware.
∫
WARNING! Install the PPC-2000 in a controlled environment,
relatively free of contaminants, to
reduce the risk of fire or electric shock.
ç
CAUTION! The controller may function incorrectly if the ambient
temperature exceeds the operating specification.
Make sure the air temperature surrounding the
controller does not exceed 140°F (60°C).
NOTE! During wiring and cabinet assembly, prevent debris
from falling inside the PPC by removing the unit from
the area, or cover the ventilation holes on the PPC
system.
