Hardwiring Cautions
• Wiring must be done by a qualied electrician.
• 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
res and other emergencies. Ensure that cables are tted 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 re 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.
• Refer to National Electrical Code (NEC) guidelines for proper wire gauge and output protection circuit requirements.
