Installation location
à
Make sure that the installation location is dry and that the pump is pro-
tected against rain, splash, gushing and drip water as well as from
other contaminants.
à
Make sure that the installation location is accessible for maintenance
and service.
à
Make sure that the pump is securely attached to the intended fastening
holes.
à
Mount the pump at the highest point in the system to prevent conden-
sate from collecting in the pump head.
à
Protect pump from dust.
à
Protect pump from vibration and impact.
Protection against foreign
objects
à
Take protective measures against touching and foreign objects which
could enter the pump.
7.2 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,
directives, regulations and technical standards.
à
Install a device for separating the pump motor from the electrical mains
in the electrical installation (in accordance with EN 60335-1).
à
Protect the pump motors in accordance with EN 60204-1 (overcurrent
protection, overload protection).
à
The motors may only be operated in an SELV circuit.
The control lines of the BLDC motor are only protected to a voltage
of up to 1.5 kV (cf. DIN EN 6100-4-2).
If higher ESD requirements are needed, measures are to be pro-
vided by the owner himself.
Refer to the pump type plate for the max. current consumption.
à
It is recommended that an additional emergency-off system be in-
stalled.
à
Mount the pumps in such a way that it is not possible to touch the elec-
trically live parts (electrical connection).
The ground potential of the power supply, the interface(s) and the
pump housing are to be at the same potential. Compensating cur-
rents via the motor controller are to be prevented as they may result
in the destruction of the electronics. A sufficient potential equaliza-
tion in accordance with EN 60479-1 is to be dimensioned.
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)
