3.2 ELECTRICAL INSTALLATION

DANGER!

 The following information is merely a guide for proper installation.

Comply with the applicable local regulations for electrical installations.

 Make sure the power supply is disconnected before starting the

installation.

 The MW500 must not be used as an emergency stop device. Provide

other devices for that purpose.

3.2.1 Identification of the Power Terminals and Grounding Points

The location of the power, grounding and control connections are shown in figure A.2.

Description of the power terminals:

 Terminal X1 (L1/L, L2/N and L3 (R, S, T, )): AC power supply.

 Terminal X2 (U/T1, V/T2, W/T3, ): connection for the motor.

 Terminal X3 (DC-, BR, DC+, ): DC bus and brake connection. DC- is the negative

pole of the voltage of the DC bus, BR is the connection of the brake resistor and

DC+ is the positive pole of the voltage of the DC bus.

3.2.2 Power and Grounding Wiring, Circuit Breakers and Fuses

ATTENTION!

 Use proper cable lugs for the power and grounding connection cables.

Refer to ta b le B.1 for recommended wiring, circuit breakers and fuses.

 Keep sensitive equipment and wiring at a minimum distance of 0.25 m

from the drive and from the cables connecting the drive to the motor.

 It is not recommended the use of mini circuit breakers (MDU), because

of the actuation level of the magnet.

NOTE!

The wire gauges listed in ta b le B.1 are approximate values. Installation

conditions and the maximum permitted voltage drop must be considered

for the proper wiring sizing.
