Warnings

The Honeywell SmartDrive is meant for fixed installations only.
Do not perform any measurements when the VFD is connected to the mains.
The ground leakage current of the Honeywell SmartDrive exceeds 3.5mA AC.
According to standard EN61800-5-1, a reinforced protective ground connec-
tion must be ensured. See chapter 1.3.
Corner grounding is allowed for the drive types with the ratings from 72 A to 310
A at 380...480 V supply and from 75 A to 310 A at 208...240 V supply.
If the VFD 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.
Futhermore, the I/O functionalities (including start inputs) may change if parame-
ters, applications or software are changed.Disconnect, therefore, the motor if an
unexpected start can cause danger.
The motor starts automatically after automatic fault reset if the autoreset func-
tion 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 VFD.
Do not touch the components on the circuit boards. Static voltage discharge
may damage the components.
Check that the EMC level of the VFD corresponds to the requirements of your
supply network.
In a domestic environment, this product may cause radio interference in which
case supplementary mitigation measures may be required.

Grounding and ground fault protection

CAUTION!
The Honeywell SmartDrive must always be grounded with a ground conductor to the ground
terminal marked with
The earth leakage current of the 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 fixed
connection and
a) the protective earthing conductor shall have a cross-sectional area of at least 10
mm Cu or 16 mm
