Page 3: Specifications
SPECIFICATIONS With this manual, we would like to give you the most important information about the correct use and maintenance of the inverter. The devices described in this manual are: § IMTP2.2M-RS: Single-phase Inverter for motor pump, max 2.2 kW (3 Hp) § ITTP2.2M-RS: Three-phase Inverter for motor pump, max 2.2 kW (3 Hp) § ITTP4.0M/W-RS: Three-phase Inverter for motor pump, max 4 kW (5.5 Hp) § ITTP5.5M/W-RS: Three-phase Inverter for motor pump, max 5.5 kW (7.5 Hp) § ITTP7.5W-RS: Three-phase Inverter for motor pump, max 7.5 kW (10 Hp) This inverters are devices specially designed for pump motor control, thanks to a perfect feed-back pressure: it assures a good energy saving and it has many programmable functions, that are not in the other common directly supplied motor pumps. -

It is necessary to avoid ground loop, that is like an antenna for EMC emission. Power supply must be admitted on working condition; donÕt lift or carry the motor pump (or the motor connected to the inverter) lifting it from the inverter. -
Page 6: Pump Hydraulic Connection
Pump hydraulic connection Connect the hydraulics according to the regulations in force. This product can work when connected to the waterworks or taking water from a water cistern. If you connect the system to the waterworks, you have to respect the regulations in force issued by local authority (Common, local authority, etcÉ). It is important to put a pressure switch on the inlet leader; it switches off the motor power in case of low pressure (it is a dry-working external protection). The inverter have two ports for a normally-closed generic contact: EN and C on the logic board (fig. 4). Verify the amount of pressure between the waterworks and the maximum pump pressure, does not exceed the maximum pump pressure value (nominal pressure) Besides, it is important to put a pressure gauge on the outlet leader, so it is possible to regulate the pressure factory setting value, according to the real conditions of the system. On the outlet leader it is necessary to install a pressure gauge with an output signal between 0 – 5 Vdc or 4 – 20 mA; this signal is an input to the inverter. As a rule it would be better to install flexible or rigid pipes on inlet and outlet branches, on-off valves on inlet and outlet branches, a no return valve, a membrane surge tank. To avoid drying the system for replacement of the membrane surge tank, pressure gauge or pressure transducer, it would be better to install some on-off valves... -
Page 7: Electric Connection To Line And Motor
The three-phase inverters ITTP2.2 and ITTP5.5/7.5 must be installed on asynchronous three-phase motor with 200-460 Vac 50/60 Hz voltage supply. The phases must be connected in star mode if the motor is 230V / 400 V (most common case, as in Fig 4). Figure 4 – Star motor phases connection The unit is equipped with output over-current protection; it is not necessary to install any additional safety device between the inverter and the pump in order to protect the motor in case of failure. -

Page 12: Starting And Programming
6. STARTING AND PROGRAMMING The starting and programming operations must be executed exclusively by experienced and qualified staff. Use the appropriate equipment and protections. To supply voltage on the Inverter verify that the Inverter box is completely closed, after having carefully followed all the instructions wiring above. The pump can not run dry; functioning under these conditions (even for a short time) irreparably damage the pump itself. For this the control system intervenes after about a minute (usually sufficient time for water loading pump during the initial service) with an alarm, stopping the pump as described in Chapter 2. -

Page 17: Replacing The Battery
6.6 Replacing the battery The lithium battery CR2032 for IMTP-ITTP2.2 and CR2430 for ITTP4/../7.5 are used exclusively for storing date and time even in the absence of power supply for a long time (the battery can live 4-6 years without inverter power supply). The lithium battery should be replaced when the user notice that the inverter does not maintain stored date and hour in the absence of power supply. NOTE: Even with exhausted or absent lithium battery remain stored all inverter functional settings indefinitely. To replacing the lithium battery it needs: 1. Disconnect the power cable from the line; 2. Open the inverter box unscrewing the No. 4 screws; 3. Wait for the complete shutdown of the led which indicates the charge of capacitors before touching any part of electronic boards; 4. Replace the battery present under the cover of the inverter. 7.

Verify if there is a no-return inlet valve on the pump and if itÕs working good without loses. ItÕs possible to reduce the flow before stopping reducing the parameter F1 ItÕs possible to reduce the flow before stopping reducing the parameter Minimum Flow Power stop % on Motor Data. The inverter donÕt switch off the Probably check was done with pump not perfectly filled up; remake the check pump when the valve on procedure after a complete filling of the pump and try again if pump switch off correctly delivery is totally closed in minimum flow condition. If the problem remain, try to grow up the function: Advanced Functions -> Motor data -> Minimum flow power stop, upgrading 2% every time and testing pump, till find the correct working. The hydraulic system have a big Probably during the automatic check there was a flow of water to full up the big tank, tank (>40 l) and, after check did for that the pump curve saved by the inverter is not the correct curve (with null flow correctly with closed delivery, and maximum pressure). the pump stop for minimum flow Maintain full of water the tank (pressure near maximum value); repeat the automatic with a high flow, and then re- check (Pump data -> check ON, then exit to the menu and press START). When the start and stop again, check finish try to work again testing the minimum flow stop condition of the motor that continuously must be with a small flow. The Inverter stop the motor for Sometimes the problem is caused by the same Automatic Check error that previous Dry Working condition point (see possible solution like above). -
