SCUBA – Additional Installation, Operation and Maintenance Instructions

 

 

The unit is equipped with built-in capacitor and motor protector, and stops automatically in 

case of overtemperature. 

After 2-4 minutes the motor protector gives the restart consent.

 

Overtemperature protection - three-phase motor unit 

Install an appropriate motor protector in the control panel, with D curve in accordance with the 

current shown in the data plate. 

Motor without automatic reset thermal overload protection 

1.

 

If the motor is used with full load, then set the value to the nominal current value on the 

data plate. 

2.

 

If the motor is used with partial load, then set the value of the operating current measured 

with a current pincer. 

4.4.3

 

Guidelines for the electrical control panel 

 

NOTICE: 

The electric panel must match the ratings on the data plate. Improper combinations could 

damage the motor. 

•

 

Install appropriate devices for protecting the motor from overloads and short circuits: 

Motor 

Safety features 

Single-phase 

•

 

Automatic reset thermal-ampere protection, built-in (motor protector) 

•

 

From short circuit, by the installer: aM fuses (motor start-up), or thermal magnetic switch 
with C curve and Icn ≥ 4.5 kA, or other similar device. 

Three-phase 

•

 

Thermal, by the installer: trip class 10 A overload thermal relay + aM fuses (motor start-

up), or start class 10 A motor protection thermal magnetic switch 

•

 

From short circuit, by the installer: aM fuses (motor start-up), or thermal magnetic switch 
with C curve and Icn ≥ 4.5 kA, or other similar device. 

•

 

If required, install phase failure sensitive thermal relays. 

4.4.4

 

Operation with frequency converter 

Single-phase and three-phase motors can be connected to a frequency converter for speed 

control. 

•

 

The converter exposes the insulation of the motor to a greater load, determined by the 

length of the connecting cable: observe the requirements of the Manufacturer of the 

frequency converter 

•

 

The minimum frequency must not fall below 25 Hz 

•

 

The head of the unit must never be below 2 m (6.5 ft) 

•

 

For applications requiring silent operation, install an outlet filter between the motor and the 

converter; a sinusoidal filter can reduce the noise even further 

•

 

The conditions of installation must guarantee protection against voltage peaks between the 

terminals and/or dV/dt in the table: 

Motor size 

Voltage peak, V 

dV/dt, V/µs 

up to 90R (500 V) 

< 650 

< 2200 

from 90R to 180R 

< 1400 

< 4600 

over 180R 

< 1600 

< 5200 

Otherwise, use a motor with reinforced insulation

1

 and a sinusoidal filter.
