3 Models with permanently attached power cords (shown):

Plug in the UPS. If the plug on the UPS’ power cord does not match your outlet (receptacle), an electrician must install the proper outlet.

Models with power cords that must be plugged in:

Do not use the cord that came with your UPS to plug it in; this cord is for connecting your equipment to the UPS. Your computer, or the equipment that you want to protect, should have a power cord that you can unplug or disconnect. Disconnect this cord from your equipment, connect the cord to the back of your UPS, and use it to plug in the UPS. Once you have plugged in the UPS, the green light on the front panel should be on. (If you need to order a UPS power cord, call the nearest Best Power office.)

4 If your FERRUPS has one or more separate battery cabinets, the battery packs should already be installed. (See the Installation Manual.) Find the red DC switch on the back of each battery cabinet. Insert the key into the DC switch and turn it all the way to the right (clockwise); then, pull the switch out to turn the DC on. When you want to turn the switch off, simply push it in — you do not need the key to turn DC off.

5 At the UPS back panel, press and hold the On/Off switch until the unit starts. AC input power must be present for the FERRUPS to start. When the unit starts, it runs on battery power briefly; then, the green light on the FERRUPS front panel will be on to show the unit is running on AC line input. Whenever the yellow light is on, the unit is running on battery power because of a power outage or power problem. When the green light is on, the display will show the following:

FERRUPS automatically charges the batteries

whenever AC input power is available. If this is the first time you’ve started the FERRUPS, let it charge the batteries for 8 hours before you go on. You can use the UPS right away, but its battery

backup time (runtime) will be shorter until the batteries are fully charged.
