2.1 Warnings – Insulating test
Warnings
ESD
When electrical replacements or disassembly is taking place, use an ESD-mat. The
internal electronics are very sensitive to static electricity.
Handling
Wear cotton gloves to avoid any fingerprints on the product.
The surfaces on the product are very sensitive, so handling should be done with
great care to avoid damage.
Cleaning of the speaker surfaces should only be done with a lint-free cloth which
you have dipped in lukewarm water and wrung firmly.
Insulation test
The product must be insulation tested after having been dismantled. Make the test
when the set has been reassembled and is ready to be returned to the customer.
Flashover must not occur during the test.
Make the insulation test as follows:
Short-circuit the two pins of the mains plug and connect them to one of the
terminals of the insulation tester.
Connect the other terminal to ground on the Power Link socket.
NOTE!
To avoid damaging the product it is essential that both terminals of the insulation
tester have good contact.
During the test the current must not exceed 5 mA.
Slowly increase the voltage on the insulation tester until a voltage of 2.5 kV (ac) is
obtained. Maintain the voltage level for one second, then slowly decrease the
voltage to 0 V (ac).
