Installation manual

This is measured by placing a digital meter set to current range of 2

Amps or more in series with the ‘Red’ back-up battery lead using

insulated crocodile clips. Now, remove the mains supply to the panel for

a few seconds and note the meter reading. if it is 850mA or above

then an additional power supply should be fitted.

Resettable Fuses (PTC)

The auxiliary and battery supplies are protected by two positive

temperature coefficient resettable fuses of 1A and 2.5A respectively. If

either rated maximum current is exceeded then the DC supply will be

interrupted until the fault is removed. This type of protection is slower

acting than a conventional fuse taking between 0 and 30 seconds to act

depending on the severity of the overload. The voltage is restored once

the fault is removed and the fuses cool down, which can take a few

seconds.
