Warnings
• Cut o the power supply before assembling the device.
NOTE: Standard power loss (Watt) = 3% of device power
∆T = Temperature dierence in the cabin (°C)
3.1 = Specific heat of air at sea level
Min. Operating Temperature = 0°C
Max. Operating Temperature = 50°C
• Wait for 5 minutes before opening the cover after the power is cut postoperation
(for the discharging of DC capacitors).
Attention!
If the device is not connected in line with the specified rules, there is always the risk of
mild and severe injury, death and material damage. Thus, all settings should be done by
expert personnel paying ultimate attention to the security warnings and precautions.

Electrical Assembly
• Cable thickness and fuse capacities should be selected according to the device input
and output current values.
• Power supply line cables and cables that control inductive load such as relay windings
must be aparted from each other and located vertically not horizontally. Control cables
must be used isolated type.
• Earth connection of device should not be short-circuited with neutral line.
Mains Supply - Device Connection
• Ensure the power supply voltage and current are compatible with the device, and
there are compatible circuit breakers between the mains and the device.
• Cut o the power on the mains before connecting the device.
• Connect the device by tightening the connectors well without leaving any naked cable
or causing short circuits.
Caution! Never use the same cable conduit.

DRIVER TERMINAL CONNECTIONS
Driver – Motor Connection
• Driver and motor current values must be checked if they are compatible
• Any kind of fuse must not be located between driver and motor.
• Motor driver connections must be four wired and shielded and connected to U,V,W
terminals of motor. In addition to this shield of cable must be connected to earth
terminal of motor and driver. Total cable length can not exceed 25 m.
NOTE : Please refer to the technical specifications section of user manual for cable
thickness.
Control Cables Connection
Shielded cable mut be used as control cables and shiled part must be grounded. (Please
do not connect to neutral)
ATTENTION: Control cables, power supply and motor cables must be separated. CAN
NOT BE LOCATED in the same cable channel.
Frequency Inverter Assembly
1Take out the inverter from the box.
2Check whether there is a physical damage.
3Locate the inverter as aluminium side up and balanced on the motor fan cover.
4Take out the assembly clamps of the inverter.
5Disassemble the upper cover by unbolting the 4 bolts located on the corner of the
cover.
6Locate M5 x 50 mm sized screws on the inverter aluminium body.
7Fix assembly clamps by screwing M5 x 50 mm screws.
8Fix assembly clamps to motor fan cover.
9Fix the inverter to the by screwing the assembly clamp screws. (M5 x 50 mm fixing
screw heads must be inside of the screw slots otherwise upper cover and gasket can
not be located properly and the parts can not be sealed.
10 Disassemble the sealing component inside the cable glands and locate cables inside
the glands.
11 Connect Transmitter, Floater and RS485 cables to spring terminals.
12 Connect motor cables including earth connection.
13 Connect power supply cables including earth connection.
14 Set MASTER-SLAVE operation micro-switches after whole cables are connected.
15 Assemble upper cover to aluminium bosy properly.
16 DO NOT switch on the power until upper cover located properly.
17 Make sure that upper cover is located properly.
18 Switch on the power supply .
19 Set the parameters according to the working condition.
20 The device will be on operation mode after leaving the set parameter mode.

SETTING PARAMETERS
Sample Parameter Setting
Setting Booster Parameters
NOTE: These settings are for the Master device.
Enter the motor current to the parameter P0007. Enter the operating pressure to the
parameter P0009 (Ex. 4.0 bar). Enter the maximum pressure of the pump to the parameter
P0015. Or set parameter P0018 and exit the program. (Note: After turning o the valve
in the delivery part (given that there are no expansion tanks between the valve and the
pump), set the autoset parameter.)
The device calculates this pressure automatically. There is no need to set the parameter
for Slave devices. It would be enough to correctly position the micro switches.
NOTE: Position the switches while there is no power in the device. The device will set itself
according to this position after connecting power.
Setting Circulating Pump Parameters
Enter the dierential pressure value of the system to the parameter P0009
(∆P, ex. 1bar). Enter the maximum pressure of the pump to the parameter
