6. A good common ground reference (Earth ground) is essential for proper operation of the DL06.
One side of all control and power circuits and the ground lead on flexible shielded cable must be
properly connected to Earth ground. There are several methods of providing an adequate common
ground reference, including:
a) Installing a ground rod as close to the panel as possible
b) Connection to incoming power system ground
7. Evaluate any installations where the ambient temperature may approach the lower or upper
limits of the specifications. If you suspect the ambient temperature will not be within the operating
specification for the DL06 system, measures such as installing a cooling/heating source must be taken
to get the ambient temperature within the range of specifications.
8. The DL06 systems are designed to be powered by 95–240 VAC or 12–24 VDC normally available
throughout an industrial environment. Electrical power in some areas where the PLCs are installed is
not always stable and storms can cause power surges. Due to this, power line filters are recommended
for protecting the DL06 PLCs from power surges and EMI/RFI noise. The Automationdirect
power line filter, for use with 120VAC and 240VAC, 1–5 Amps, is an excellent choice (locate at
automationdirect.com); however, you can use a filter of your choice. These units install easily between
the power source and the PLC.
NOTE: If you are using other components in your system, make sure you refer to the appropriate
manual to determine how those units can affect mounting dimensions.
Using Mounting Rails
DL06 Micro PLCs can be secured to a panel by using mounting rails. We recommend rails
that conform to DIN EN standard 50022. They are approximately 35 mm high, with a depth
of 7 mm. If you mount the Micro PLC on a rail, do consider using end brackets on each side
of the PLC. The end bracket helps keep the PLC from sliding horizontally along the rail,
reducing the possibility of accidentally pulling the wiring loose. On the bottom of the PLC
are two small retaining clips. To secure the PLC to a DIN rail, place it onto the rail and gently
push up on the clips to lock it onto the rail. To remove the PLC, pull down on the retaining
clips, lift up on the PLC slightly, then pull it away from the rail.
NOTE: Refer to our catalog or web site for a complete listing of DINnector connection systems.
