GENERAL
Barcrest make use of a wide range of components in the manufacture of their product, which are in turn
supplied by a large number of manufacturers.
Due to its limitations, it is not practical for this manual to contain all the relevant safety data for these
products.
If required, the manufacturer’s data sheets can be supplied.
All parts used in Barcrest products are used within their specification limits and in accordance with sound
engineering practice.
1.1
ELECTRICAL SAFETY
CAUTION RISK OF ELECTRIC SHOCK
230 Volts is present within the machine.
Only suitably qualified personnel should carry out servicing of the machine.
Disconnect from the mains supply before disconnecting, removing or touching any internal components.
SAFE CONNECTION TO SUPPLY
To ensure the safe operation of this machine it must be connected to the mains supply using an
approved power cord, which meets the requirements of IEC227.
This cord must have an IEC approved connector at one end and an approved 13-amp plug fitted with a
5-amp fuse at the other. In the case of non-fused power cords, an approved and suitably rated Residual
Current Device shall be used.
INSULATION/EARTH BOND
Insulation and earth bond electrical safety checks are made on all Barcrest machines before despatch.
These tests should be then be undertaken annually, or whenever safety critical parts or connections are
replaced.
Insulation \ earth bond specifications for Barcrest machines are as follows: -
Insulation > 9.9 Meg ohm @ 500V
Earth Bond < 0.1 ohm @ 25 amps
1.2
CHEMICAL SAFETY
Some component parts of Barcrest products contain small quantities of chemicals, which are to be
considered hazardous should the components be accidentally damaged.
These are: -
Electrolytic capacitors
Semiconductors containing Beryllium Oxide and Gallium Arsenide
Opto-electronic devices using Gallium Phosphide
Because of the corrosive or flammable nature of these chemicals, particular care is required in the case
of spillage. Where these chemicals do come into contact with the skin or eyes, the affected area must be
flushed with cold running water, and medical advice sought.
