Connect the AC Input Supply
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 transceiver'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 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) supplied with the transceiver, 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 Voltages
up to and Including 450/750 V (designation H05 RR-F)’.
The T6TR transceiver is a Class 1 equipment. The ac supply cable should have a green-and-yellow
protective earthing conductor electrically connected to the protective earthing terminal of the equipment
connector and the mains plug. Park Air recommends the ac supply cable is colour coded in accordance
with the electrical appliance (colour code) regulations for the UK. That is:
WARNING Dangerous Voltages
WARNING Earth Connection

‰
The core coloured green-and-yellow must be
connected to the terminal in the plug that is
marked with the letter E or by the earth symbol
or coloured green-and-yellow.
‰
The core coloured blue must be connected to
the terminal that is marked with the letter N or
coloured black.
