Reflected wave protection
The drive should be installed as close to the motor as possible. Installations with long motor cables
may require the addition of external devices to limit voltage reflections at the motor (reflected wave
phenomena). See Table 1.E for recommendations.
The reflected wave data applies to all frequencies 2 to 10 kHz. For 240V ratings, reflected wave
effects do not need to be considered.

Reflected wave
380 ~460V Ratings
Motor insulation rating Motor cable only*
1000 Vp-p 15 meters (49 feet)
1200 Vp-p 40 meters (131 feet)
1600 Vp-p 170 meters (558 feet)
* Longer cable lengths can be achieved by installing devices on the output of the drive. Consult factory for recommendations.
Output disconnect
The drive is intended to be commanded by control input signals that will start and stop the motor.
A device that routinely disconnects then reapplies output power to the motor for the purpose of starting
and stopping the motor should not be used.
If it is necessary to disconnect power to the motor with the drive outputting power, an auxiliary contact
should be used to simultaneously disable drive control run commands.
Power terminal Block
The drive utilizes a finger guard over the power wiring terminals.
To remove:
1. Press in and hold the locking tab.
2. For the finger guard on the top of the drive, slide it down and out.
For the finger guard at the bottom of the drive, slide it up and out. Replace the finger guard when
wiring is complete.
