Frame 6 Transformer Tap Access (AC Input Drives Only)
The transformer is located behind the Power Terminal Block shown in figure 3.2.
Access is gained by releasing the terminal block from the rail. To release terminal
block and change tap:
Step 1. Locate the small metal tab at the bottom of the end block.
Step 2. Press the tab in and pull the top of the block out. Repeat for next block if
desired.
Step 3. Select appropriate transformer tap.

3.1.2 Making Sure Environmental Conditions are Met
Important: Failure to meet the following conditions may result in erratic operation
and/or drive damage.
Before deciding on an installation site, consider the following guidelines:
• Verify that NEMA 1 enclosure drives can be kept clean and dry.
• The area chosen should allow the space required for proper air flow as defined in
section 3.1.3.
• Be sure that the NEMA 1 enclosure is installed away from oil, coolants, or other
airborne contaminants.
• Do not install the drive above 1000 meters (3300 feet) without derating output
power. For every 91.4 meters (300 feet) above 1000 meters (3300 feet), derate the
output current 1%.
• Verify that the drive location will meet the environmental conditions specified in
Appendix A.
!
ATTENTION: Ensure that all power to the drive has been removed
before performing the following. Failure to follow this precaution could
result in a shock hazard.
!
ATTENTION: DC bus capacitors retain hazardous voltages after input
power has been removed. After disconnecting input power, wait five
minutes for the DC bus capacitors to discharge and then check the
voltage with a voltmeter to ensure the DC bus capacitors are discharged
before touching any internal components. Failure to observe this
precaution could result in severe bodily injury or loss of life.
