! CAUTION
To reduce the risk of fire, connect only to a circuit provided with 20 amperes maximum branch circuit overcurrent protection in accordance with the national code, ANSI/NFPA 70.
•Do not connect equipment that may overload the UPS or demand half-wave rectification, such as a laser printer.
•Connect the UPS only to an earthed / grounded outlet that meets national and local electrical safety guidelines.

See Step 8 for installation instructions.
The UPS must be placed indoors, protected from water, direct sunlight and excessive heat.
Provide at least 4" (100mm) of clearance on all sides of the unit for proper ventilation.
The UPS battery is not charged before shipping. It MUST be charged before use.
•Connect the UPS power cord to a wall outlet and charge for at least eight hours. Unit can be charged in the on or off state.
Note: If battery is placed in storage, charge the battery every six months if kept at 5°F to 85°F (-15°C to 29°C)—or every three months if kept at 86°F (30°C) or higher.
After the battery is fully charged:
•Turn on the UPS by pressing the On/Off button (see Figure 1 below).
LED 1 should be illuminated (green), indicating the UPS is operating in Normal Mode.
• Check the rear of the UPS to make sure the Site Wiring Fault indicator is
NOT illuminated.
Caution: If the Site Wiring Fault indicator is illuminated, have a qualified electrician check the wall receptacle wiring and fix any problems.
The UPS has three battery backup outlets that provide power when the UPS operates on battery. There is also one surge-only outlet (see
Figure 2 below).
• Plug the loads into the battery backup outlets on the rear of the UPS.
Caution: Do not connect a laser printer to the UPS.
The UPS has two network cable jacks for network lines
(see Figure 2 below).
• Connect a single-line network cable into the network surge protection IN jack on the rear of the UPS.
• Connect a network cable from the OUT jack on the rear of the UPS to a port on a PC or network device such as a router.
To start using the Liebert MultiLink software:
• Install the software.
See the Liebert MultiLink quick-start guide or user manual for installation instructions.
• Connect one end of the USB cable (supplied) to the USB port on the rear of the UPS. Connect the other end to a USB port on the computer.
See the Liebert MultiLink user manual for operating instructions.
Note: Emerson recommends connecting the USB cable directly to the computer WITHOUT using a USB hub.
