AC Supply Connection
The equipment is permanently connected to the mains supply when the mains connector is
attached. Switching the rear panel Power switch to Off does not isolate all internal circuits
from the mains supply. For this reason, a mains isolating switch should be fitted close to,
and easily accessible from, the MDR's position. The isolation switch should isolate both live
and neutral supplies, be clearly labelled, and adequately rated to protect the equipment.
