à
Mount the pump at the highest point in the system to prevent conden-
sate from collecting in the pump head.
à
Protect the pump from dust.
à
Protect the pump from vibration and impact.
Installation position
à
The pump can be mounted in any installation position. Use metal
screws to fasten the pump at the indicated attachment points.
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).
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)
