WARNING
Personal injury and/or property damage from vi-
brations
Pump vibrations, in combination with adjacent
components, can result in crushing and/or dam-
age to these components.
à
Make sure that pump vibrations cannot lead
to dangers in combination with adjacent com-
ponents.
Protection against foreign
objects
à
Protect the pump against contact and the ingress of foreign bodies.
6.2 Electrical connection
DANGER
Danger to life from electric shock
à
Only have the pump connected by an autho-
rized specialist.
à
Only have the pump connected if the power
supply is disconnected.
à
When connecting to a power source, observe the applicable standards,
regulations, directives, and technical standards.
à
When connecting to a power source, carefully read and observe the
motor operating instructions (including the notice on insulation resis-
tance measurement).
WARNING
Automatic restart after interruption of the power
supply
If the power supply is interrupted or the thermal
overload fuse of the motor is activated, the pump
will automatically restart.
à
Take appropriate protective measures.
à
Install a device for separating the pump motor from the electrical grid in
the electrical installation (e.g. in accordance with EN 60335-1).
à
Protect the pump motors, e.g., in accordance with EN 60204-1 (over-
current protection, overload protection).
Refer to the type plate for the maximum current consumption of the
pump.
à
Install an EMERGENCY OFF device such that it is not possible for
there to be an automatic restart or for hazardous situations to persons
and property to occur.
à
Install the pumps in such a way that it is not possible to touch electri-
cally live parts (electrical connection).
Fastening the connection cables
à
Fasten the connection cables so that
– the cables do not come into contact with movable or hot parts.
– the cables cannot be worn or damaged on sharp corners or edges
– no tensile and pressure forces are exerted on the connection point
of the cables (strain relief)
