Read and understand the following notes while planning your installation:
1. Refer to national and local electrical codes for acceptable external wiring practices.
2. Material and labor for external wiring requirements are to be provided by designated
personnel.
3. For external wiring, use 90°C copper wire.
See the appropriate column in Tables A, B, and O.
4. Refer to the appropriate UPS installation manual for UPS module and optional equipment
installation notes.
5. A bypass neutral feeder must be installed when the output neutral is used. If no bypass
neutral is installed, the output neutral is to be bonded to the chassis in the SSBM through
a minimum size copper conductor listed in Table H on Sheet 3 of Drawing 164201373---3.
In either case, fully rated neutral conductors are to be run from the output of each UPM to
the neutral buss bar inside the SSBM.
NOTE: The required neutral conductors must be spread evenly as possible between
the available neutral runbacks.
6. External overcurrent protection is not provided by this product, but is required by codes.
Refer to Tables A, B, and O for wiring requirements. If an output lockable disconnect is
required, it is to be supplied by designated personnel.
7. Terminals E1 through E17 are 2-hole bus bar mountings for standard NEMA 2-hole barrel
lugs. The Frame Ground is a single hole bus bar mounting for NEMA 1-hole barrel lugs.
Refer to Table C for power cable terminations. Refer to drawing 164201373---13 for the
location of the power cable terminals inside the SSBM.
8. The system supports either a single common battery shared by all UPS modules or a
separate battery for each UPS module. The system supports either valve regulated lead
acid batteries or flooded (wet cell) batteries.
9. The rectifier inputs and bypass input three phase feeds should be symmetrical about ground,
due to the existence of voltage surge protection devices.
10. The line-to-line unbalanced output capability of the UPS is limited only by the full load per
phase current values for AC output to critical load. The recommended line-to-line load
unbalance is 50% or less.
11. The SSBM can be equipped for separate input feeds for the SSBM Bypass input and the
SMB Bypass input or for a single input feed for both the SSBM Bypass Input and the SMB
Bypass Input.
