Plug the UPS into a two-pole, three-wire grounding receptacle only. Avoid the use of extension cords and adapter plugs.

■220/230/240 Vac version

The 220/230/240 Vac version UPS is not furnished with an input line cord. Instead, two output cords are supplied. However, in most installations you will not need to purchase a UPS input power cord. Simply swap the line cords from your equipment with the furnished output cords, and plug in the UPS using one of the equipment cords.

If your equipment does not have a removable line cord, the provided rewireable plug may be installed on the line cord. Additional output cords and adapter plugs are available from your dealer and from the factory.

The UPS may be configured to operate where 240 Vac, 50 Hz service is provided. When Option Switch 2 is set to the on (down) position, the UPS’s transfer and on-battery output voltages are adjusted for proper operation on 240 Vac service (see Sec. 5.4).
