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EU states should also comply with the following unless superseded by local or National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 re-

placed. 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.

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 iso-

lating switch. If 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 stan-

dards.

7. Where equipment or covers are marked with the symbol to the right, haz-

ardous 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 symbol to the right, there

is a danger from hot surfaces beneath. These covers should only be re-

moved by trained service personnel when power is removed from the

equipment. Certain surfaces may remain hot to the touch.
