Safety
1.2
Warnings
Drive is meant for fixed installations only.
Do not perform any measurements when the AC drive is connected to the mains.
The earth leakage current of drives exceeds 3.5mA AC. According to standard
EN61800-5-1, a reinforced protective ground connection must be ensured. See
chapter 1.3.
If the AC drive is used as a part of a machine, the machine manufacturer is respon-
sible for providing the machine with a supply disconnecting device (EN 60204-1).
Only spare parts delivered by Honeywell can be used.
At power-up, power brake or fault reset the motor will start immediately if the start
signal is active, unless the pulse control for Start/Stop logic has been selected.
Furthermore, the I/O functionalities (including start inputs) may change if parameters,
applications or software are changed.Disconnect, therefore, the motor if an unex-
pected start can cause danger.
The motor starts automatically after automatic fault reset if the auto restart function
is activated. See the Application Manual for more detailed information.
Prior to measurements on the motor or the motor cable, disconnect the motor
cable from the AC drive.
Do not touch the components on the circuit boards. Static voltage discharge may
damage the components.
Check that the EMC level of the AC drive corresponds to the requirements of your
supply network.
1.3
Earthing and earth fault protection
CAUTION!
The drive must always be earthed with an earthing conductor connected to the earthing termi-
nal marked with
.
The earth leakage current of drive exceeds 3.5mA AC. According to EN61800-5-1, one or more
of the following conditions for the associated protective circuit shall be satisfied:
a) The protective conductor shall have a cross-sectional area of at least 10 mm

16 mm
Al, through its total run.
b) Where the protective conductor has a cross-sectional area of less than 10 mm
2
16 mm
Al, a second protective conductor of at least the same cross-sectional area
shall be provided up to a point where the protective conductor has a cross-sectional
area not less than 10 mm
c) Automatic disconnection of the supply in case of loss of continuity of the protective con-
ductor.
