SECTION 1 - SAFETY NOTES
1.1 - General
Barcrest Group 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 Group products are used within their specification limits and in accordance with sound
engineering practice.
1.2 - Electrical Safety
1.2.1 - 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.
1.2.2 - 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.
For equipment with a permanently connected power cord-
If the supply cord is damaged, it must be replaced by the manufacturers, its service agents, or similarly qualified persons, in
order to avoid a hazard.
1.2.3 - Insulation \ Earth Bond
Insulation and earth bond electrical safety checks are made on all Barcrest Group 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 Group machines are as follows: -
Insulation > 9.9 Meg ohm @ 500V
Earth Bond < 0.1 ohm @ 25 amps
1.3 - Chemical Safety
Some component parts of Barcrest Group products contain small quantities of chemicals, which are to be considered
hazardous should the components be accidentally damaged.
These are: -
•
Electrolytic capacitors
•
Nickel-metal hydride batteries
•
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
.
1.4 - Fire Safety
The components used in Barcrest Group products are in the main, housed in a heat resistant material.
NB: Where component parts are replaced; only components of identical value must be used and that the correct
polarity be observed during insertion.
Severe electrical overload conditions could create sufficient heat so as to ignite chemicals within components themselves,
other components in close proximity, machine wiring harnesses etc.
Materials used, which are in the fire hazard category, are:
