QUICK START GUIDE
This guide is a supplement to the application manual supplied with the drive. Improper wiring can cause bodily harm and damage the equipment. Follow good wiring practices and all applicable codes and standards.
MODEL NAMEPLATE
- Verify you received the correct model drive.
- Compare the drive nameplate VOLTS and AMPS rating with the motor or compressor nameplate.
- Check that the power source meets the input power requirements.
- Output power from the drive should match the motor requirement.
KEYPAD AND DISPLAY
- Use and arrows to navigate a menu list and change parameter values.
- Use arrow to enter parameter group mode and arrow to back up one step.
- Programmable Soft Key 1
- Increase Value Scroll Menu Up
- Back/Reset Button
- Stop/Off Button
- Move Cursor Left
- Enter Menu Confirm Selection

AC POWER WIRING
- Locate the power terminal strip.
- Check the AC voltage rating shown on the drive nameplate with the AC incoming voltage.
- Turn the power off and make connections.
I/O WIRING
Refer to the EVH Install Manual for the complete I/O wiring guide.

FREQUENTLY ASKED QUESTIONS
Q: How do I reset the drive back to factory default settings?
A: Hold the OFF/STOP and BACK/RESET buttons for 5 seconds to return drive to
factory default.
Q: How do I adjust the time it takes the motor to speed up or slow down?
A: To adjust the time for the motor to accelerate to set speed, find parameter
P1.3 (accel time). To adjust the time for the motor to decelerate to 0, find
parameter P1.4 (decel time).
Q: How do I prevent the drive from tripping on an overvoltage fault while
my motor is ramping down?
A: Make the deceleration time longer for your ramp down, check input voltage,
or activate overvoltage controller in parameter P5.1.12.
Q: Can I run my motor above the nominal motor speed?
A: The motor should be run within the speed range specified by the
manufacturer. For Copeland™ compressors, please see AE-1466 for allowed speed
ranges.
