Safety instructions related to
maintenance
This chapter D describes the main preventive maintenance
operations and provides a guide for first diagnosis in the event of
an incident.
Electric shock hazard on touching.
When the main isolator is switched to the «0» position, items located
between the mains connection and the isolator are still under mains
voltage.
Disconnect the mains cable from all power sources before commencing
any maintenance work on the product.
Electric shock hazard.
Some components have capacitors charged to over 60VDC. When power
is switched off, they keep their charge for a time. Residual voltages
from the filter capacitors can cause electric shocks all the way back to
the mains plug. Wait 5 minutes after power-off before commencing any
work on the appliance.
Maintenance must be performed by a skilled maintenance operator
trained in the relevant health and safety aspects (EMC, electrical hazards,
chemical pollution, etc.).
Isolate the product from all energy sources (mains electricity, compressed
air, etc.) before starting work.
Located on the covers of the pump, this label warns the user against
possible risk of injury due to any hand contact with hot surfaces.
It states that protective gloves should be used before performing any
intervention.
HOT SURFACE
Contact with pump bodies may cause burn.
Switch off and wait until pumps cooled
before servicing.
WARNING
Located on the upper cover, this label indicates that some of the
internal parts are energized and could cause electrical shocks in case
of contact. It advizes to disconnect the pump before any intervention
or to properly lock-out and tag-out the equipment breaker before
any intervention on the pump.
WARNING
HAZARDOUS VOLTAGE
Switch off the pump and
disconnect the main power cable
before opening the power box cover.
Located on the upper cover, this label warns
the user against pumped process gas that could
be dangerous and toxic and could cause severe
injuries or death. It specifies that any preventive
maintenance operation can only be performed
by trained personnel.
