The Eaton 9155 has the following power connections:
• 2-phase (L1 and L2), neutral, and ground connection for rectifier/bypass input
• 2-phase (L1 and L2), neutral, and ground connection for load output
CAUTION
• The input isolation transformer output is always 240V (180° phase angle).
• If installing a Maintenance Bypass Module (MBM) or Power Distribution Module (PDM), the UPS MUST be
set up for 240V output only; otherwise, the “Bypass Not Available” alarm annunciates. Any equipment
connected to the output requiring 208V (120° phase angle) is at risk for damage when using the
maintenance bypass switch.
Output overcurrent protection and disconnect switch must be provided by others.
Figure 39 and Figure 40 show the oneline diagrams of the input isolation transformer with the UPS.
WARNING
Only qualified service personnel (such as a licensed electrician) should perform the UPS installation and initial
startup. Risk of electrical shock.
To hardwire the input isolation transformer and UPS (all hardware is supplied in the accessory kit):
1. Verify that the electrical connections to the installation site have been properly installed.
2. A wall-mounted, user-supplied, readily-accessible disconnection device must be incorporated in the input
wiring.
Compare the circuit breaker ratings and wire sizes to the specifications in Table 5 .
