ELECTRICAL CONNECTIONS
Before switching the product on, make sure that the voltage of your electricity supply is
the same as that indicated on the rating plate. This product is designed to operate on
230VAC 50Hz. Connecting it to any other power supply may cause damage.
This product may be fitted with a non-rewireable plug. If it is necessary to change the
fuse in the plug, the fuse cover must be refitted. If the fuse cover becomes lost or
damaged, the plug must not be used until a suitable replacement is obtained.
If the plug has to be changed because it is not suitable for your socket, or due to
damage, it should be cut off and a replacement fitted, following the wiring instructions
shown below. The old plug must be disposed of safely, as insertion into a mains socket
