B.1 Safety instructions for the wiring and
installation of this apparatus
The following safety instructions apply specifically to all EU member states. They should be
strictly adhered to in order to assure compliance with the Low Voltage Directive. Non-EU
states should also comply with the following unless superseded by local or national
standards.
1. Adequate earth connections should be made to all earthing points, internal and
external, where provided.
2. After installation or troubleshooting, all safety covers and safety grounds must be
replaced. The integrity of all earth terminals must be maintained at all times.
3. Mains supply cords should comply with the requirements of IEC227 or IEC245.
4. All wiring shall be suitable for use in an ambient temperature of greater than 75 °C
(167 °F).
5. All cable glands used should be of such internal dimensions as to provide adequate
cable anchorage.
6. To ensure safe operation of this equipment, connection to the mains supply should
only be made through a circuit breaker which will disconnect all circuits carrying
conductors during a fault situation. The circuit breaker may also include a
mechanically operated isolating switch. If it does not, then another means of
disconnecting the equipment from the supply must be provided and clearly marked
as such. Circuit breakers or switches must comply with a recognized standard, such
as IEC947. All wiring must conform with any local standards.
7. Where equipment or covers are marked with the following symbol, hazardous
voltages are likely to be present beneath. These covers should only be removed
when power is removed from the equipment - and then only by trained service
personnel.
8. Where equipment or covers are marked with the following symbol, there is a danger
from hot surfaces beneath. These covers should only be removed by trained service
personnel when power is removed from the equipment. Certain surfaces may
remain hot to the touch.
