Revision 002 User’s and Installation Guide
Table 3-5: Separate rectifier input UPM ratings and external wiring requirements for the 9395P 500 kVA / 600 kVA
Read and understand the following notes while planning and performing the installation:
• Refer to national and local electrical codes for acceptable external wiring practices.
• Material and labor for external wiring requirements are to be provided by designated personnel.
• The bypass feed into this equipment uses three or four wires. The rectifier feed into this
equipment uses three wires. The phases must be symmetrical about ground (from a Wye source)
for proper equipment operation.
• On a UPS configured for separate rectifier inputs, all sources that feed the separate rectifier inputs
must be derived from a common ground point.
• If the load requires a neutral, a bypass source neutral must be provided. If the load does not
require a neutral and there is no neutral conductor connected at the bypass input, an optional
neutral forming kit must be used.
• This UPS system can be installed to the TN, TT or IT power distribution systems.
NOTE
Additional warning labels, shown in Figure 5-7, shall be installed at the UPS input terminals and
all primary power isolators used to isolate the UPS unit if:
• the UPS system is installed to an IT power distribution system
• or the UPS input is connected through external isolators that, when opened, isolate the
neutral connection.
• These warning labels can be obtained from your local service representative.
• The UPS cabinet is shipped with a debris shield covering the ventilation grill on top of the unit. Do
not remove the debris shield until installation is complete. However, remove the shield before
operating the UPS. Once the debris shield is removed, do not place objects on the ventilation grill.
