At the UPS and the optional battery cabinet, you will find a leveler next to each caster. Using a wrench, turn
each leveler counterclockwise to lower it and keep the UPS from moving. Next, find the two long brackets
that were attached to the top of the UPS packing crate. (The battery cabinet does not have brackets.) Attach
these brackets to the sides of the UPS as shown in Figure 4 on page 6 to stabilize the UPS.

4. Refer to the wiring diagram and use the tables below to find the proper size circuit breaker for the AC input

service panel. UPS input and output overcurrent protection are provided on the back panel of the UPS.

You must provide some means for disconnecting input AC within sight of the UPS. Best Power
strongly recommends including a means of bypassing the UPS from the critical load for maintenance.
AC input cables should be protected against overcurrent by fuses or automatic circuit breakers.

5.  At the back of the UPS, find the box shown on the back panel.

Remove the cover by removing the four screws that hold the
cover on the box. (The box on the B610010K model is shown;
the B6106000 box is similar.)

There are three knockouts/plugs in the bottom of this box.
Remove the two left knockouts for AC input and AC output.
If you have a B610010K model with a separate battery
cabinet, remove the third knockout or plug for the DC cables.

Install the conduit adapters. AC input and AC output
conductors must be run through separate conduit. UPS output
circuits shall be installed in dedicated conduit systems and not
shared with other electrical circuits.

6.  Use the wiring diagram (Figure 7 on page 9) and the terminal

block label shown on the next page to make the UPS terminal
strip connections and complete the AC installation wiring.
Read the notes below the diagram carefully. See Figure 8
for UPS output terminations.

wire size for each circuit breaker size shown on

the wiring diagrams. The minimum recommended circuit breaker sizes for each
model and voltage application are listed on the wiring diagrams.

The conductor size shall be no smaller than the 75° C wire size based on the
ampacities given in Tables 310-316 of the National Electrical Code, ANSI/NFPA
70-1993, and article 220. All circuit conductors, including the neutral and
equipment grounding conductors, must be the same size (ampacity) wire. Code
may require a larger AWG size than shown in this table because of temperature,
number of conductors in the conduit, or long service runs. Follow local code
requirements.
