1. IPFC Introduction

IPFC is a variable frequency drive designed to control and protect pumping systems by varying the output frequency to the

pump.

IPFC can be applied to both new and existing pumping systems, and provides:

energy and cost savings

simplified installation and an overall lower pumping system cost

longer life of the pumping system and relevant components

improved reliability

IPFC, when connected to any pump, manages the system operation to maintain a certain constant physical quantity

(pressure, differential pressure, flow, temperature, etc.) regardless of the conditions of use. The pump is operated only when

needed thus avoiding unnecessary energy consumption.

IPFC at the same time is able to:

protect the motor from overload and dry running

implement soft start and soft stop to increase the system life and reduce current peaks

provide an indication of current consumption, voltage, and power

maintain a record of run time and display any errors and/or failures reported by the system

control up to two additional pumps at a constant speed (Direct On Line)

connect to other IPFC units for combined operation

Through the use of inductive filters (optional) IPFC eliminates dangerous surges that are induced in long cables, making IPFC

suitable for control of submersible pumps.

2. Safety Instructions

The manufacturer strongly suggests carefully reading this operation manual before using and installing its products

Any operation (installation, maintenance and repair) must be carried out by trained, skilled, and qualified personnel.

Failure to observe and follow the instructions in this manual may result in dangerous and potentially lethal electric shock.

Pay attention to all standard safety and accident prevention regulations

The device must be connected to main power supply via a switch to ensure the

complete disconnection from the network before any operation on the IPFC itself

(including visual inspection) and/or on the connected load.

Disconnect IPFC from the main power supply before commencing any work.

Do not remove, for any reason, the cover and the cable plate without having first

disconnected the device from the main power supply and having waited at least

5 minutes.

IPFC and pumping system must be grounded properly before operation.

For the entire period IPFC is powered, high voltage is present on the output

terminals of the inverter whether or not the pump is running.

Tightening all screws on the cover with washers is recommended before

powering the device. Otherwise, there may be a failure to connect the cover to

ground, creating the risk of electric shock or even death.

Avoid any shock or significant impact during transport.

Check the IPFC immediately upon delivery and check for damage and/or missing parts. If either occurs, immediately notify

the supplier.

Damages due to transport, incorrect installation, or improper use of the device will null and void the warranty.

Tampering or disassembly of any component will automatically void the warranty.

The manufacturer cannot be held responsible for any damages to people and/or property due to improper use of its

products.

Devices marked with this symbol cannot be disposed of in household waste but

must be disposed of at appropriate waste drop-off centres. It is recommended

to contact the Waste Electrical and Electronic Equipment drop-off centres

(WEEE) in the area. If not disposed of properly, the product can have potential

harmful effects on the environment and on human health due to certain

substances present within. Illegal or incorrect disposal of the product is subject

to serious administrative and/or criminal penalties.
