Drive Programming
If the default PWM frequency is greater than the maximum drive
carrier frequency listed on page 3, you must re-program the drive to a
value that is less than or equal to the maximum drive carrier
frequency.
Grounding
Follow the recommended grounding practices provided in your drive
User Manual. The following illustration shows an example of the
system grounding practices.
Important: If you cannot connect the terminator directly to the motor
mounted junction box, an auxiliary junction box can be
used. However, the terminator-to-motor connection length
should be no more than 6 meters (20 feet).
If installed in hazardous location, an auxiliary junction box
rated Class 1, Division 2 must be used.
You can power up the system once proper installation, drive
programming, and grounding is completed.

ATTENTION: The National Codes and standards (NEC,
VDE, BSI, etc.) and local codes outline provisions for safely
installing electrical equipment. Installation must comply
with specifications regarding wire types, conductor sizes,
branch circuit protection, and disconnect devices. Failure
to do so may result in personal injury and/or equipment
damage.
