Instructions
• both 9-volt batteries located inside the control unit must be connected.
• Power cables L1, L2, L3, N and PE should be connected to their appropriate jacks.
• It is mandatory that cables N and PE are connected and connected properly.
• The power supply cable to the control unit must be equipped with a main On / Off switch
• Each phase of the main power cable must be equipped with a fuse with a max rating
of 16 Amps
• Improper cable connection (Phase and N reversed) will cause the internal fuse (315
mAT) to blow.
• The 2 x motor / pump cables U/V/W should be connected to the T1 / T2 / T3 connection
jacks. Pump 1 connections are on the left, Pump 2 connections are on the right.
• The PE cable is to be connected to the TF1 and TF2 jacks on the connection block lo-
cated below the motor protection switch. Pump 1 connections are on the left, Pump 2
connections are on the right.
• Pump 1 and Pump 2
• Cable number 4 on the motor supply cable should be connected to lowest jack on the
TF2 TF1 connection area.
• Cable 5 on the motor supply cable should be connected to the middle jack on the TF2
TF1 connection area.
• Cable 6 on the motor supply cable should be connected to the top jack on the TF2 TF1
connection area. The 2 polar 'bridge' must be removed if present.
The cable ends of the float switches are to be connected to the appropriate connec-
tion jacks in the HAZARD area inside the control unit which are protected by the elec-
trical shield.
• The 'Störung' (malfunction) and 'Alarm' (alarm) control unit signals are controlled by a
relay. Inductive loads must be externally eliminated. The stand by (powerless) position
of the relays is printed on the board. This means the 'Warning' and 'Alarm' signals are
activated.
• 42 V ac dc / 0,5 A

5.7 Completion of electrical work

After all electrical connection work has been completed in the
control unit, the control unit cover must be closed and pro-
perly secured. In order to eliminate odour nuisances in the
area where the control unit is installed, the conduit pipe to the
control unit should be sealed with a special gaskets or sim-
ply with insulation foam.
