ONSIDERATIONS
Please refer to your local codes and requirements for inline fusing
between the resistor and drive. Special considerations may apply, as a
blown fuse in the DC will remove the braking load, and may lead to loss
of braking torque. Review the safety standards required for your
application.

EQUIREMENTS
Using the ground lug provided, ground the chassis in accordance with
local codes. Typically the wire gauge will be the same as is used to
ground the attached drive.

IRING
The M3575R Resistive Load is equipped with an Over-Temp contact for use
with existing drive or system interlock circuitry. Please refer to the system
documentation for field control interlock connection details. When installing
M3575R modules in parallel, it is recommended that the over-temperature
contacts of these units be connected in series as shown in Figure 3-5.
Actual connection points and terminal numbers for the AC Drive module
should be found in the documentation provided with the drive. Be sure to
review all pertinent drive and system documentation before proceeding.
