Also avoid short-term unit overloads, which may, for example,

occur when connecting a laser printer or laser fax machine.

Do not connect any household appliances to the UPS.

Never connect any additional loads to the UPS

if there is a mains failure, i.e. if the UPS is

working in emergency power operation.

The UPS output is de-energised if there is an overload of 150 %

for longer than 200 ms during normal operation. During

emergency power operation, an instant shutdown additionally

takes place if there is a unit overload of > 120 % (see Chapter

3.4). As a rule, if there has never been an overload during

normal operation, there will not be one during battery

operation either.

5.5.4 System Diagnosis / Battery Test

It is possible to press the "TEST" button

(pos. 2 p. 42) to

perform a manual check on the major hardware components

of the UPS. This test can only be initiated if the unit is

operating normally, and it involves switching the loads over to

UPS inverter supply for a few seconds. As well as checking

the procedures and the functional capability of the static

bypass switch, this check also involves drawing current from

the battery for a short time. The inverter has to provide the

entire load supply, which means the entire process chain is

tested with this function. Normal operation is restored after the

check.
