1 - SAFETY CONSIDERATIONS
1.1 - General
Installation, start-up and servicing of equipment can be hazard-
ous if factors particular to the installation are not considered:
operating pressures, electrical components, voltages and the
installation site itself (elevated plinths, rooftops and built-up
structures).
Only highly trained and qualified installation engineers and
technicians, who are fully trained on the product, are authorised
to install and start up this equipment.
During all servicing operations, it is important to read, under-
stand and follow all the recommendations and instructions
given in the installation and service instructions for the product,
including the tags and labels affixed to the equipment, compo-
nents and any parts supplied separately, and to comply with all
other relevant safety regulations.
• Apply all safety codes and practices.
• Wear safety glasses and gloves.
• Use the proper tools to move heavy objects. Move units
carefully and set them down gently.
1.2 - Avoiding electrocution
Only personnel qualified in accordance with the recommendat-
ions of the IEC (International Electrotechnical Commission)
may be permitted access to electrical components. It is parti-
cularly recommended that all sources of electricity to the unit
be shut off before any work is begun. Shut off the main power
supply at the main circuit breaker or isolator.
IMPORTANT:
Risk of electrocution: Even when the main power isolator or
circuit breaker is off, it is still possible for certain compo-
nents such as crankcase heaters and trace heaters to be
energised, since they are connected to a separate power source.
Even when the unit is switched off, the power circuit remains
energised, as long as the unit or circuit disconnect is not open.
Refer to the wiring diagram for details.
Attach appropriate safety labels.
Risk of burns: Electrical currents cause components to get
hot either temporarily or permanently. Handle power cables,
electrical cables and conduits, terminal box covers and motor
frames with very great care.
IMPORTANT: This equipment uses and emits electromagnetic
signals. The tests carried out on this product have shown that
it complies with all applicable codes regarding electromagnetic
compatibility.
IMPORTANT : If the boards need to be handled wear anti-
static gloves to avoid exposing the electronic components to a
destructive voltage. Only unpack the boards from their anti-
static bag when they need to be installed.
