SAFETY INSTRUCTIONS
IMPORTANT
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the following unless superseded by local or National Standards.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.
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 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 symbol
to the right, 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 symbol
to the right, 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.
9. Where equipment or covers are marked with the symbol
to the right, refer to the Operator Manual for instructions.
10. All graphical symbols used in this product are from one
or more of the following standards: EN61010-1, IEC417,
and ISO3864.
11. Where equipment or labels are marked "Do Not Open While Energized"
or similar, there is a danger of ignition in areas where an explosive
atmosphere is present. This equipment should only be opened when
power is removed and adequate time as specified on the label or in the
instruction manual has been allowed for the equipment to cool down -
and then only by trained service personnel.
