Electrical Connections - general
The electrical connections to the counter-current swimming system must be carried out by
a specialised company in the electrical engineering branch approved by the local energy
provider, taking into account the technical connection requirements.
Please observe:
•
The mains power connection must be a fixed connection.
•
Under no circumstances must there be any conducting connection between the metal
parts of the motor and the water.
•
An earth leakage circuit breaker (nominal fault current
≤
30 mA) must be fitted to the
mains power connection.
•
The mains power supply cable must be equipped with an all-pole separator with a con-
tact opening of 3 mm.
•
At the marked connection terminal (at the foot of the motor or next to the terminal box)
an equalising potential with a cross-section of 10 mm² must be fitted.
•
The counter-current swimming system must only be operated provided that the termi-
nal box lid is closed!
5.1.1
Direction of rotation check
In the case of 3~ motors the direction of rotation must be the same as the direction of ro-
tation arrow on the blower cover of the counter-current swimming system .
Warning! Mortal danger!
The connections must be carried out by a qualified electrician.
For this refer to the
TAB of the EVS
, the
VBG 4(§3)
and
DIN VDE 1000-10/
1995-5, for example
.
The relevant
DIN VDE (Association of German Engineers) regulations
0100
and in the case of explosion protection
0165
must be observed.
If the installation is not carried out properly, there is a risk of getting electric
shocks!
Warning!
Compare the available power supply voltage with the details on the motor’s
factory plate and select the appropriate switching.
We recommend the use of a motor protection facility. Explosion protected mo-
tors, increased safety (Ex)–e and temperature class T3, must always be con-
nected in accordance with DIN VDE 0170/0171 via a motor protection switch.
Connect the motor in accordance with the circuit diagrams in sections 5.3 and
5.4.
Warning!
Check by rapidly switching on and off.
If the direction of rotation is wrong for 3~ motors, change any two phases L1,
L2 or L3 of the power supply in the motor terminal box over.
