Checking the ac Input Fuse
For continued protection against risk of fire, replace only with the same type and rating of
fuse.
The ac input fuse is located in a pull-out holder that is an integral part of the ac connector. Check that the
fuse type is of the correct rating:
100 - 240V T4AH 250V IEC (Park Air part number,
29E01120108S)
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.
This equipment must be earthed. The earth terminal of the ac connector should be used as
the safety earth.
An ac input connector (see Fig 8 and Fig 12) is fitted to the equipment’s rear panel. The cable used to
connect between the equipment and the user’s ac power source should be 3-core (to IEC 227) rated
250 Vac at 8 amps, and have a minimum cross-sectional area of 1.0 mm
2
per core. Park Air recommends
the use of polyvinyl chloride (PVC) insulated cable. The cable must be fitted with the IEC approved
equipment connector (Park Air part number 20-02030102) and conform to the following specification:
‰
If PVC insulated, be not lighter than ordinary polyvinyl chloride sheathed flexible cord according
to IEC publication 227 (designation H05 VV-F, or H05 VVH2-F).
‰
If rubber insulated, be of synthetic rubber and not lighter than ordinary tough rubber-sheathed
flexible cord according to IEC publication 245 titled ‘Rubber Insulated Cables of Rated Voltage up
to and Including 450/750 V (designation H05 RR-F)’.
