WARNING
Only qualified service personnel (such as a licensed electrician) should perform the UPS installation. Initial
startup must be performed by an authorized Eaton Customer Service Engineer. Risk of electrical shock.
To hardwire the bypass cabinet:
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 to the ones in Table 6.
3. Switch off utility power to the distribution point where the bypass cabinet and UPS will be connected. Be
absolutely sure there is no power.
4. Determine your equipment's grounding requirements according to your local electrical code.
5. Unfasten the bypass cabinet front door latch and swing the door open (see Figure 33).
6. Follow the instructions on the inside of the door to open or remove the front cover (see Figure 33 and
