1. Safety
This manual contains clearly marked cautions and warnings which are intended for your per-
sonal safety and to avoid any unintentional damage to the product or connected appliances.
Please read the information included in cautions and warnings carefully.
The cautions and warnings are marked as follows:
Table 1. Warning signs
1.1 Danger
= DANGEROUS VOLTAGE!
= WARNING or CAUTION
The components of the power unit of the SmartDrive are live when the VFD
is connected to mains potential. Coming into contact with this voltage is
extremely dangerous and may cause death or severe injury.
The motor terminals U, V, W and the brake resistor terminals are live when
the drive is connected to mains, even if the motor is not running.
After disconnecting the VFD from the mains, wait until the indicators on the
keypad go out (if no keypad is attached see the indicators on the cover). Wait 5
more minutes before doing any work on the connections of the drive. Do not open
the cover before this time has expired. After expiration of this time, use a measur-
ing equipment to absolutely ensure that no
voltage is present. Always ensure
absence of voltage before starting any electrical work!
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 drive is disconnected from mains.
Before connecting the VFD to mains make sure that the front and cable covers
of the drive are closed.
During a ramp stop (see the Application Manual), the motor is still generating
voltage to the drive. Therefore, do not touch the components of the VFD before
the motor has completely stopped. Wait until the indicators on the keypad go out
(if no keypad is attached see the indicators on the cover). Wait additional 5 min-
utes before starting any work on the drive.

Honeywell • 3 Safety
1.2 Warnings
1.3 Grounding and ground fault protection
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
mm2Cu or 16 mm2Al.
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.
CAUTION!

or
b) an automatic disconnection of the supply in case of discontinuity of the protective
earthing conductor.
or
c) provision of an additional terminal for a second protective earthing conductor of the
same cross-sectional area as the original protective earthing conductor.
Table 2. Protective earthing conductor cross-section
The cross-sectional area of every protective grounding conductor which does not form part of
the supply cable or cable enclosure shall, in any case, be not less than:
-2.5mm
2if mechanical protection is provided or
-4mm
2if mechanical protection is not provided. For cord-connected equipment, provi-
sions shall be made so that the protective earthing conductor in the cord shall, in the
case of failure of the strain-relief mechanism, be the last conductor to be interrupted.
NOTE! Due to the high capacitive currents present in the VFD, fault current protective switches
may not function properly.
1.4 Electro-magnetic compatibility (EMC)
This equipment complies with IEC 61000-3-12 provided that the short-circuit power SSC is
greater than or equal to 120 at the interface point between the user’s supply and the public sys-
tem. It is the responsibility of the installer or user of the equipment to ensure, by consultation
with the distribution network operator if necessary, that the equipment is connected only to a
supply with a short-circuit power SSC greater than or equal to 120.

sponding protective earthing conductor

S/2
The values above are valid only if the protective earthing conductor is made of the same metal as
the phase conductors. If this is not so, the cross-sectional area of the protective earthing conductor
shall be determined in a manner which produces a conductance equivalent to that which results
from the application of this table.
Do not perform any voltage withstand tests on any part of the drive. There is a
certain procedure according to which the tests shall be performed. Ignoring this
procedure may result in damaged product.

BACnet - general info Honeywell • 6
2. BACnet - general info
BACnet stands for ‘Building Automation and Control Networks’. It is the common name for the
communication standard ISO 16484-5 which defines the methods and the protocol for cooper-
ating building automation devices to communicate. Devices can be designed to operate using
BACnet communication protocol as well as utilising BACnet protocol to communicate between
systems. BACnet is an internationally accepted protocol for building automation (e.g. lightning
control, air conditioning and heating automation) and control over a communications network.
BACnet provides a method by which computer-based control equipment, from different manu-
facturers can work together, or 'interoperate'. For this to be achieved, components must be able
to exchange and understand BACnet data messages.
Your Honeywell SmartDrive is equipped with BACnet support as standard.

Strip about 15 mm of the RS485 cable (see specification on page 8) and cut off
the grey cable shield. Remember to do this for both bus cables.
Leave no more than 10 mm of the cable outside the terminal block and strip the
cables at about 5 mm to fit in the terminals. See picture below.
Also strip the cable now at such a distance from the terminal that you can fix it to
the frame with the grounding clamp. Strip the cable at a maximum length of 15
mm. Do not strip the aluminum cable shield!
4Then connect the cable to its appropriate terminals on Honeywell SmartDrive
standard terminal block, terminals A and B (A = negative, B = positive). See
