Page 32: Initial Energization
Before releasing the drive system for regular operation after installation, the system must be adjusted and tested by qualified YORK or Johnson Controls personnel. This start-up labor is included in the sale of each MVVSD, to ensure reliable and safe performance. It is important to make arrangements for such a check and that time is allowed for it.
Page 33: Unit Conversion
To convert a temperature range (that is, a range of 10°F) from Fahrenheit to Celsius, multiply by 5/9 or 0.5556. Example: 10.0°F range x 0.5556 = 5.6 °C range Medium Voltage Variable Speed Drive Installation © 2025 Johnson Controls. All rights reserved.
