appropriate terminal posts as designated in the power supply unit.<br />

2.1 Battery test<br />

The power supply unit features an automatic battery load test. The battery load test is an effective<br />

instrument for checking the true battery state. A negative result, i.e. a warning message is issued, may<br />

be caused by one or more of the following:<br />

• Charge status too low.<br />

• Battery fuse has failed.<br />

• Battery not correctly connected.<br />

• Battery is defective.<br />

• Battery is too old, and must be replaced.<br />
