Overvoltage category 2. Pollution degree 1.
Mains supplies of 110V, 240V or 12V DC are all suitable. The AC voltage selector is on the
rear of the unit. When operating from mains supplies, the integrity of the supply earth should
be checked to maintain electrical safety. The mains cable should be protected by a fast fuse of
no greater than 6 amps in the supply feed.
