General Installation Information
This chapter provides general information on mounting and wiring the
PowerFlex 700L Liquid-Cooled AC Drive.
Enclosure Ratings
PowerFlex 700L Liquid-Cooled AC drives have the following enclosure
ratings:
• Open-Chassis Style (IP00) - Frame 2: Intended to be installed in an
enclosure. Frame 3: Input filter and power modules, when purchased
individually, are intended to be mounted in an enclosure.
• Type 1 (IP20) - Frame 3: Drive is mounted in a separate NEMA/UL Type
1 enclosure to obtain this rating.
PowerFlex 700L Liquid-Cooled AC drives must be placed in an enclosure.
See the catalog string on page P-5
for fully assembled NEMA/UL Type 1
drive options.
AC Supply Source
Considerations
PowerFlex 700L Liquid-Cooled AC drives are suitable for use on a circuit
capable of delivering up to a maximum of 200,000 rms symmetrical
amperes. For the PowerFlex 700L Frame 3A or 3B complete drive, a circuit
breaker with shunt trip with the appropriate kAIC rating must always be
used upstream of the power module. See Table 1.A
for details.
PowerFlex 700L Liquid Cooled AC drives should not be used on undersized
or high-impedance supply systems. The supply system kVA should be equal
to or greater than the drive-rated kW, and the system impedance should be
less than 10%. Operation outside these limits could cause instability
resulting in drive shutdown.
System Impedance = (PowerFlex 700L kVA ÷ Transformer kVA) x Transformer % Impedance
The kVA of all PowerFlex 700L drives on the distribution system and the
system impedance of upstream transformers should be taken into account.
