In case of low priority alarms (see 3.4.2.2) the buzzer will not immediately sound but only after a certain

delay in order to avoid frequent buzzer activity during momentary alarm situations (e.g. overload,

temperature, weak mains). The buzzer delay time does not affect buzzer operation during alarms with

high priority.

Setting 'ON' means that the function is activated: the UPS will switch off during a mains failure when the

load is < 5% of the maximum load. Be careful with very small loads: e.g. a fax machine in stand-by mode

could be recognised by the UPS as a no-load situation.

In order to generate reliable runtime predictions the UPS needs to be informed about the total battery

capacity. The Ah value shown in the display is the programmed capacity and should indicate the capacity

of the standard internal battery plus the capacity of the battery extension pack(s).

If the NetPro is supplied by a generator set, and the generator's frequency is often out of the UPS's input

tolerances, frequently occurring 'bypass error' alarms (see 3.4.2.2) will be the result. During these alarms

bypass operation is inhibited. To avoid this situation the bypass function can be disabled: the UPS

functions as a UPS without automatic bypass switch.

If NO is selected, i.e. if the bypass function is disabled, the default screen alternates every 10 seconds

with the following message, displayed during 2 seconds:

The output frequency can be set to 50/60 Hz.

NOTE: The unit can be used as a frequency converter: the input frequency range is 45-66Hz, the output

frequency is selectable 50/60Hz. If the unit is used as a frequency converter, the bypass function is no

longer available. As a result an audible alarm will be generated continuously (see 3.4.2.2 'Bypass error').

To avoid this, we advise to disable the bypass (see above).

WARNING:

Changing of the output frequency can cause severe damage of equipment connected to

the appliance outlets of the UPS: Be sure that the new frequency is suitable for the

connected equipment!
