7.0 INSTALLATION
CAUTION
VERY IMPORTANT
Supply voltage must be kept to a maximum imbalance of 2% on 50Hz and 3% on 60Hz applications. Voltage
imbalances greater than these levels can cause permanent damage to the drive.
Compressor must not be subjected to any voltage spikes or surges in excess of 575V. Exposure to spikes/surg-
es in excess of 575V can permanently damage the drive. If the possibility of such exists it is recommended
that adequate surge protection is fitted such as an Ingersoll Rand line reactor. See your local Ingersoll Rand
representative.
Failure of the drive due to voltage spikes, line notching, harmonics or other power quality related problems,
will not be covered by the standard compressor warranty.
The correct type and rating of line input fuse MUST BE fitted onto the customers isolator or breaker close to
the compressor. For Amp rating see technical information in Section 8.1.
Product Identification
Class - J, Class - T, or
Semiconductor
Fuse Type
Fast Acting Class-J, T or Semiconductor type,
Current limiting, Interrupt Rating - 200,000 Amps
RMS SYM.
Alternate fuse may be used if the time current
characteristics are faster than fuses recommended
in this section.
See your local
Ingersoll Rand
representative for a range of fuses and disconnect isolators matched to your particular
machine.
Example of voltage imbalance calculation
U
→
V 462v
V
→
W 459v
W
→
U 453v
V(m) = (462 + 459 + 453) / 3 = 458v
VΔ max = 462 - 453 = 9v
∴
= (9 / 458) x 100 = 1.97%
