7.3 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 regula-
tions, directives, and technical standards.
à
Install a device for separating the pump motor from the electrical mains
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
Mount 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)
Thermal switch/PTC thermistor
sensor
The motors are equipped as standard with a thermal switch (capaci-
tor motor) or with PTC thermistor sensor (three-phase motor) to
monitor against overheating (see operating instructions for the mo-
tor).
The three-phase motors are suitable for operation with frequency
converters (see operating instructions for the motor).
Connecting the pump
1. Confirm that the supply voltage meets the parameters listed on the
pump nameplate. Refer to the pump nameplate for the rated current
consumption.
2. Electrically connect the pump.
3. Open the terminal box cover.
4. Connect the ground conductor to the pump motor.
Set the direction of rotation according to the arrow on the fan cowl
(see
7.1 Installing the pump and the motor operating instructions).
5. Connect the electrical power cables in accordance with Fig. 7 and
Fig. 8 (three-phase motor) or Fig. 9 (capacitor motor) (cf. motor oper-
ating instructions).
