2-2 Mounting and Wiring Your 1336 IMPACT Drive
Before Mounting Your Drive Before mounting your drive, consider the following:
• what tools and equipment you need to mount your drive
• the distance between the motor and the drive
• the distance between the drive and other surfaces
Important: Before you mount your drive, you need to thoroughly
read and understand the information presented in this chapter. You
should take every precaution to complete the wiring as instructed.
Required Tools and Equipment
At a minimum, you will need the following tools and equipment to
mount your drive:
• a small regular screw driver
• a medium phillips screw driver
• a box end wrench or socket set
• wire strippers
Distance Between the Motor and the Drive
If the distance between the motor and the drive requires long motor
cables, you may need to add an output reactor or cable terminators to
limit voltage reflections at the motor. The following tables show the
maximum length cable allowed for various installation techniques.
Values shown in Table 2.A are for 480V nominal input voltage and
drive carrier frequency of 2 kHz. Consult factory regarding operation
at carrier frequencies above 2 kHz. Multiply values by 0.85 for high
line conditions. For input voltages of 380, 400 or 415V AC, multiply
the table values by 1.25, 1.20 or 1.15, respectively.
Values shown in Table 2.B are for nominal input voltage and drive
carrier frequency of 2 kHz. Consult factory regarding operation at
carrier frequencies above 2 kHz. Multiply values by 0.85 for high line
conditions.
If these tables indicate that your motor cables are not over the
maximum cable length for your motor, you probably do not need a
terminator or output reactor.
