WARNING

HOT SURFACE

1

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

when NXL is connected to mains potential. Coming into contact with

 

 

this voltage is extremely dangerous and may cause death or severe

 

injury. The control unit is isolated from the mains potential.

2

The motor terminals U, V, W (T1, T2, T3) and the DC-link/brake resistor

terminals –/+ (in NXL 1.1 kW) are live when NXL 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 NXL 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.

 

7

The heat sink of types MF2 and MF3 may be hot when the frequency

converter is in use. Coming into contact with the heat sink may cause

 

 

burns.

The Honeywell NXL frequency converter is meant for fixed installations only.

Do not perform any measurements when the frequency converter is connected to the mains.

After disconnecting the frequency converter from the mains, wait until the fan stops and the indicators on the display go out. Wait 5 more minutes before doing any work on NXL connections.

Do not perform any voltage withstand tests on any part of NXL. There is a certain procedure according to which the tests shall be performed. Ignoring this procedure may result in damaged product.

Prior to measurements on the motor or the motor cable, disconnect the motor cable from the frequency converter.

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