2. Product introduction

2.1 Product description

Grundfos MGE 71-160 are frequency-controlled permanent-magnet motors for single-phase or three-phase mains connection. The motors
incorporate a PI controller.
You can connect the motors to a signal from an external sensor and a setpoint signal enabling control in closed loop. You can also use the
motors for an open-loop system in which the setpoint signal is used as a speed control signal.
The motors incorporate an operating panel which is available in various versions.
Detailed motor settings are made with Grundfos GO Remote. Furthermore, you can read important operating parameters via Grundfos GO
Remote.
The motors incorporate a functional module. The functional module is available in various versions with different inputs and outputs.
You can fit the motors with a Grundfos add-on communication interface module (CIM). The module enables data transmission between the
motor and an external system, for example a BMS or SCADA system. The module communicates via fieldbus protocols.
You can connect several motors together via radio or bus communication to create a multimotor system.

2.2 Intended use

The product is intended for machines with a square torque characteristic, such as ventilators and centrifugal pumps.

2.3 Radio module

The product incorporates a class 1 radio module for remote control. You can use the module anywhere in the EU without restrictions.
For installation in the USA and Canada, see appendix A. For installation in Brazil, see appendix B.
Some variants of the product and products sold in China and Korea have no radio module.
Via the built-in radio module, the product can communicate with Grundfos GO Remote and other MGE motors.

2.4 Battery

A Li-ion battery is fitted in the advanced functional module, FM 300.
The Li-ion battery complies with the Battery Directive (2006/66/EC). The battery does not contain mercury, lead or cadmium.

2.5 Drain holes

The motor has a plugged drain hole on the drive side. The drain hole is placed in the flange on the drive side. You can turn the flange 90 ° to
both sides or 180 °.
With the drain hole open, the motor becomes self-venting, allowing water and humid air to escape.
When you open the drain hole, the enclosure class of the motor will be lower than standard.
