COMPUTER/LAN INTERFACE (400/600 VA ONLY)
Optional SiteNet 1 kits provide connection to a wide range of popular computer
operating systems; such as Novell, UNIX, UNISYS, SUN, WINDOWS and many
others. SiteNet 1 software automatically performs an orderly shutdown of
computer operating systems, in the event of a power outage and/or low battery
conditions.
The SiteNet 1 kit supplies a cable to connect supported computer systems to the
UPS communications port (10). The table below shows connector details.
Note: Your dealer supplies
computer communications kits
separately, if you wish. They come
with installation instructions, cable
connections, and appropriate
computer software.
OPTION SWITCH SETTINGS
On the back of your UPS is a bank of option switches (6) with a removable
plastic cover. These switches determine transfer levels and operating frequency.
Slide the switches to the left to turn them OFF, to the right to turn ON. Turn OFF
equipment and UPS and unplug the UPS prior to changing switch settings, or the
UPS will ignore the new settings. Replace the plastic option switch cover.
Option Switch 1: 50/60 Hz Select – When OFF, this switch sets UPS for 60 Hz
mains. Output in backup mode will be 60 Hz. When ON, the switch sets UPS for
50 Hz mains and output in backup mode is 50 Hz. The switch must match the
mains frequency or the UPS will not start. The factory setting is 50 Hz.
Option Switch 2: High Line Transfer –
250VA model: When ON, this switch transfers the UPS to battery operation
when the mains voltage reaches 270 VAC. When OFF, the UPS will not
transfer to battery. Factory setting is ON.
400/600VA models: You may select at which voltage the UPS will transfer to
battery operation when it encounters a high mains voltage. The ON position
transfers the UPS to battery operation at 270VAC; the OFF position transfers at
280VAC. Factory setting is 270 VAC.
