Electrical connection 

6.10.1

 

Safety instructions 

 

Danger 

 

Danger of injury from electric voltage. 

 

High shock currents and burns from direct and indirect contact with 

live parts. 

 

Turn off the power supply before assembling the compact 

booster unit and secure it from being turned on. 

 

Non- or erroneously-connected cables 

 

Malfunctions, which endanger the safety of operating personnel. 

 

Work on electrical equipment may only be performed by specia- 

list electric technicians. 

 

Observe regulation IEC 30364 (DIN VDE 0100) and for explo- 

sion protection IEC 60079 (DIN VDE 0165). 

 

Faulty mains connection 

 

Damage to the electricity network, short circuit! 

 

Observe the conditions for technical connections of the local 

power supply companies. 

 

Wrongly wired connections 

 

Destruction of electrical / electronic components. 

 

Work on electrical equipment may only be performed by specia- 

list electric technicians. 

 

Improperly connected wiring and lines (e.g. too small bend radius) 

 

Smouldering and fires from cables. 

 

Work on electrical equipment may only be performed by specia- 

list electric technicians. 

 

Live cable ends and components 

 

Make sure the protective earth system is connected throughout. 

   

Always observe DIN 14462 for electrical connections. 

6.10.2

 

Connection specifications 

Power supply connection 

3/N/PE, AC 400V, 50Hz 

Control transformer 

400V / 230V- 24V 

The circuit diagrams of the respective systems are kept in the switching 

device and should always remain there. The documentation included 

with the switch cabinet contains a list of electronic parts. Please always 

specify the circuit diagram number when ordering spare electronic 

parts. 

 

The diameter of the electrical supply line has to be determined according 

to the total connection value. 

 

The customer required protection measures for the electrical connection 

of the system is defined in DIN 14462. 

6.10.3

 

Connecting electrical accessories 

 

Caution 

 

Terminal resistor for the connection of the remote on/off is missing or 

not connected properly 

 

Danger of system malfunction! 

 

There is a 10kOhm terminal resistor connected to the connector 

clamps for remote on/off (limit switch). If multiple messaging 

lines have been connected, it has to be positioned behind the 

last limit switch. 

 

The relay for monitoring wire breakage and short circuit 

evaluates the following resistances: >10.3kOhm: Wire brea- 

kage 10kOhm: Fully operational 1kOhm: Pump start through 

use of a limit switch <300Ohm: Short circuit A wiring scheme 

for the external remote on/off switch is included with the system. 

The external messaging line has to be wired according to the 

values specified above. 

The switch cabinet is equipped with the following clamps for connecting 

electrical accessories: 

 

Remote on/off for connecting limit switches 

The clamps are labelled in the diagram and in the cabinet. 

6.10.4

 

Connecting the limit switch 

Connect the limit switch to the remote on/off connecting clamps as follows: 

 

 

Figure 8: 

Setting without limit switch 

 

 

Figure 9: 

Setting with limit switch 

 

 

Figure 10:  Setting for two limit switches 

a)  First limit switch 

b)  Last limit switch 

 

 

Figure 11:  Setting for more than two limit switches 

a)  First limit switch 

b)  Second limit switch 

c)  Last limit switch 

6.10.5

 

Potential-free contacts 

Potential-free contacts are available for the following messages: 

 

Motor protection warning 

 

Collective error message for pump requirements, pump overheating, 

control voltage missing , mains power failure and short circuit/wire brea- 

kage 

 

Buffer tank overflow 

 

Water shortage 

 

Switch to position manual/automatic 

 

Separation of potable water 

 

Failure of power supply from backup battery 

The clamps are labelled in the diagram and in the cabinet. 

   

Forward alert messages to the control unit. 

Potential-free collective error message can be created by looping throu- 

gh of potential-free single messages.
