Configuration 4-9
■
If the utility voltage frequently varies outside the UPS operating range
(see Fig 4-6), consider changing from normal to extended range
(+20% to –35%). This provides more tolerance to brief utility voltage
fluctuations.
To update the nominal voltage and operating range parameters:
1.
Have a qualified electrician monitor utility voltage.
2.
Use the following tables to identify the operating range that most closely
matches requirements:

For nominal voltage level setting, select configuration parameters
1, 2, 3, or 10 (see Table 4-1).
4.
Access parameter 4 to switch from normal to extended range (see
Table 4-1).
