to the work area, so that the unit can be switched off quickly in case of

emergency. Refe to ‘Electrical Connections’ on page 12. Fuse ratings

are

given in the Specification chart on page 2.

Make sure that the mains supply switch and any fuses have a value which
is the same or 20% above the maximum current absorbed by the unit.
