Connection
Wiring must be done by a qualified electrician.
The UPS may be installed on its own or connected to an isolation transformer. Both applications require the UPS to be connected to a battery pack.
When making wiring connections, observe the cable connection regulations appropriate to your area [e.g. National Electrical Code (NEC)
in the U.S.] at all times. Be sure to install an easily accessible disconnect switch in your installation wiring so you may cut off the UPS’s
AC input during fires and other emergencies. Ensure that cables are fitted with cable sleeves and are secured by connector clamps. Tighten
connections with a torque of not less than 24-28 inch-pounds (2.7-3.2 NM).
Make sure that your equipment is properly grounded.
Using cables of improper size may damage your equipment and cause fire hazards. Choose appropriate cabling and protection circuits to
make wiring connections (Ground conductors must be the same size and type as the power conductors used):
