Only qualified service personnel (such as a licensed electrician) should perform the UPS
installation and initial startup. 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 3 on
page 47.
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 28).
6. Follow the instructions on the inside of the door to open or remove
the front cover (see Figure 28 and Figure 29).
