Warnings
The Honeywell Smart VFD HVAC is meant for fixed installations only.
Do not perform any measurements when the drive is connected to the mains.
The touch current of the Honeywell Smart VFD HVAC exceeds 3.5mA AC.
According to standard EN61800-5-1, a reinforced protective ground connec-
tion must be ensured. See chapter 1.3.
If the drive is used as a part of a machine, the machine manufacturer is
responsible 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 drive.
Do not touch the components on the circuit boards. Static voltage discharge
may damage the components.
Check that the EMC level of the drive corresponds to the requirements of your
supply network. See chapter 5.2.
In a domestic environment, this product may cause radio interference in which
case supplementary mitigation measures may be required.
1.3
Grounding and ground fault protection
CAUTION!
The Honeywell Smart VFD HVAC AC drive must always be grounded with an grounding con-
ductor connected to the grounding terminal marked with
The touch 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:
1. A fixed connection and
a) the protective earthing conductor has a cross-sectional area of at least 10 mm
or 16 mm
Al through its total run.
2
b) an automatic disconnection of the supply in case of loss of continuity of the protective
conductor. See chapter 4.
