ONLY A COMPETENT ELECTRICIAN SHOULD CARRY OUT

THE ELECTRICAL INSTALLATION

1.1 Warnings

WARNING

1

The components of the power unit of the frequency converter are live

when the NX is connected to mains potential. Contact with this voltage

 

 

is extremely dangerous and may cause death or severe injury. The

 

control unit is isolated from the potential.

2

The motor terminals U, V, W and the DC-link/brake resistor terminals –/+

are live when the NX is connected to mains, even if the motor is not

 

 

running.

3

The control I/O-terminals are isolated from the mains potential. However,

the relay outputs and other I/O-terminals may have a dangerous control

 

 

voltage present even when the NX is disconnected from mains.

4

The frequency converter has a large capacitive leakage current.

 

5

If the frequency converter is used as a part of a machine, the machine

manufacturer is responsible for providing the machine with a main switch

 

 

(EN 60204-1).

6

Only spare parts delivered by Honeywell can be used.

 

1.2 Safety instructions

1

The NX frequency converter is meant for fixed installations only.

 

2

Do not perform any measurements when the frequency converter is

connected to the mains.

 

3

After disconnecting the frequency converter from the mains, wait until the

fan stops and the indicators on the keypad extinguish. (if no keypad is

 

 

attached see the indicators on the cover). Wait 5 more minutes before

 

doing any work on the NX connections. Do not even open the cover

 

before this time has expired.

4

Do not perform any voltage withstand tests on any part of the NX. There

is a defined procedure for making this test. Ignoring this procedure may

 

 

result in damage to the frequency converter.

5

Prior to measurements on the motor or the motor cable, disconnect the

motor cable from the frequency converter.

 

6

Do not touch the IC-circuits on the circuit boards. Static voltage discharge

may damage the components.

 

7

Before connecting the frequency converter to mains, ensure that the

frequency converter front and cable covers are closed.
