Power adapter The optional power adapter (AP9505, not supplied) is for 100/
120 V systems only, if required. The power adapter is required
under the following conditions:
• Smart-UPS
– Serial number prior to S9405
– Serial number starting with the letter W
– All Smart-UPS 250 models
• Matrix-UPS
– When remote turn-on of the UPS is required.
If you need to obtain a power adapter contact APC Customer
Service at a telephone number on the back cover, if needed.
Decide whether to connect the AC adapter into a
wall outlet or a protected UPS Outlet. If the
device needs to function during a power outage
connect the power adapter into one of the AC
outlets on the UPS. If remote turn-on operation is
required connect the power adapter into a wall
outlet. See “Operation” on page 4 before install-
ing any UPS accessory in the Expansion Chassis.
