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
Install a device for disconnecting 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
It is recommended that an additional EMERGENCY STOP device be
installed.
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)
Connecting the pump
1. Compare the data of the supply voltage with the information on the
type plate. See the pump type plate for the maximum current con-
sumption of the pump.
