Dryer Master DM510 Installation Manual
The conclusion is that ground system configuration plays an important role in surge protection.
Therefore, Dryer Master installations must attempt to minimize the effects of improper grounding
by ideally installing the grounds as a star-point system.
Figure 24 - Dryer Master internal grounding shows the internal grounding that is installed in the
DM510. This is done to enhance the grounding capabilities by connecting the ground wires that
power the remote sensors to the ground lug in the DM510 chassis. It is important that these wires
remain in place along with the new wires placed at these locations during the installation process.
These wires provide an extra path for surge current to dissipate.

Note:
Post 2015 I/O
Jumpers have
been replaced
with high current
Traces on the
circuit board.
For the DI & DO
pin jumpers are
provided behind
the connector to
isolate the circuits
if required.
