1. SAFETY
This manual contains clearly marked cautions and warnings which are intended for your personal 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:
= DANGEROUS VOLTAGE!
= WARNING or CAUTION
Table 1. Warning signs
1.1 Danger
The components of the power unit of the drive are live when the drive 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 drive 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 measuring equipment to absolutely ensure that no
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 drive to mains make sure that the front and cable covers
of the drive are closed.
During a coast stop (see the Application Manual), the motor is still generating
voltage to the drive. Therefore, do not touch the components of the drive 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 minutes before starting any work on the drive.
voltage is present.
Always ensure
1
Honeywell • 3 SAFETY
1.2 Warnings
The drive is meant for fixed installations only.
Do not perform any measurements when the drive is connected to the mains.
The touch current of the drives exceeds 3.5mA AC. According to standard
EN61800-5-1, a reinforced protective ground connection 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. Remember to change the EMC level by removing the jumpers. See chapter 6.3.
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 parameters, 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 6.3.
In a domestic environment, this product may cause radio interference in which
case supplementary mitigation measures may be required.
1.3 Earthing and earth fault protection
CAUTION!
The drive must always be earthed with an earthing conductor connected to the earthing 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:
A fixed connection and

or
b) an automatic disconnection of the supply in case of discontinuity of the protective

case of failure of the strain-relief mechanism, be the last conductor to be interrupted.
However, always follow the local regulations for the minimum size of the protective
earthing conductor.
NOTE: Due to the high capacitive currents present in the drive, fault current protective switches
may not function properly.
Do not perform any voltage withst and test s on any p art of the drive. There is a
certain procedure according to which the tests shall be performed. Ignoring this
procedure may result in damaged product.
1.4 EMC levels
SmartDrive HVAC inverters are divided into three classes according to the le vel of electromagnetic disturbances emitted, the requirements of a power system network and the installation
environment (see below). The EMC class of each product is defined in the type designation
code.
Category C1 (Honeywell EMC class C): Inverters of this class comply with the requirements
of category C1 of the product standard EN 61800-3 (2004). Category C1 ensures the best EMC
1
Honeywell • 5 SAFETY
characteristics and it includes converters the rated voltage of which is less than 1000V and
which are intended for use in the 1st environment. This EMC class is meant for highly sensitive
areas and can be sometimes required in installations in e.g. hospitals or airport control towers.
NOTE: The requirements of class C1 are fulfilled only as far as the conducted emissions are
concerned with an external EMC-filter.
Category C2 (Honeywell EMC class H): All Honeywell SmartDrive HVAC inverters comply
with the requirements of category C2 of the product standard EN 61800-3 (2004). Category C2
includes converters in fixed installations and the rated voltage of which is less than 1000V. The
category C2 inverters can be used both in the 1st and the 2nd environment. This category fulfills the requirements with normal installations in buildings.
IT networks (Honeywell EMC class T): Inverters of this class fulfil the product standard EN
61800-3 (2004) if intended to be used in IT systems. In IT systems, the networks are isolated
from earth, or connected to earth through high impedance to achieve a low leakage current.
NOTE: if inverters configured to IT network are used with other supplies, no EMC requirements
are complied with. SmartDrive HVAC inverters can be easily modified to the requirements of
the T-class. This class is very typical requirement also in installations in ships. Also the 230V
SmartDrive HVAC products can be ordered as ready configured to this class by adding a T to
the end of standard product code (HVAC230-xxx-xxT).
Environments in product standard EN 61800-3 (2004):
First environment: Environment that includes domestic premises. It also includes establishments directly connected without intermediate transformers to a low-voltage power supply network which supplies buildings used for domestic purposes.
NOTE: houses, apartments, commercial premises or offices in a residential building are examples of first environment locations.
Second environment: Environment that includes all establishments other than those directly
connected to a low-voltage power supply network which supplies buildings used for domestic
purposes.
NOTE: industrial areas, technical areas of any building fed from a dedicated transformer are
examples of second environment locations.
1.4.1 Total Harmonic Distortion (THD)
This equipment complies with IEC 61000-3-12 provided that the short-circuit power S
SC
is
greater than or equal to 120 at the interface point between the user’s supply and the public system. 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 S
greater than or equal to 120.

4.1 UL standards on cabling
To meet the UL (Underwriters Laboratories) regulations, use a UL-approved copper cable with
a minimum heat-resistance of +60/75°C. Use Class 1 wire only.
The units are suitable for use on a circuit capable of delivering not more than 100,000 rms symmetrical amperes, 600V maximum.
4.1.1 Cable dimensioning and selection
Table 14 shows the minimum dimensions of the Cu/Al-cables and the corresponding fuse sizes. Recommended fuse types are gG/gL.
These instructions apply only to cases with one motor and one cable connection from the drive
to the motor. In any other case, ask the factory for more information.
POWER CABLING Honeywell • 22
4.1.1.1 Cable and fuse sizes, frames MR4 to MR6
The recommended fuse types are gG/gL (IEC 60269-1) or class T (UL & CSA). The fuse voltage rating should be selected according to the supply network. The final selection should be
made according to local regulations, cable installation conditions and cable specification. Bigger fuses than what is recommended below shall not be used.
Check that the fuse operating time is less than 0.4 seconds. Operating time depends on used
fuse type and impedance of the supply circuit. Consult the factory about faster fuses. Honeywell offers recommendations also for high speed J (UL & CSA ), aR (UL recognized, IEC
60269-4) and gS (IEC 60269-4) fuse ranges.

The cable dimensioning is based on the criteria of the International Standard IEC60364-5-52:Cables
must be PVC-isolated; Max ambient temperature +30°C, max temperature of cable surface +70°C; Use
only cables with concentric copper shield; Max number of parallel cables is 9.
When using cables in parallel,
area and the max number of cables must be observed.
For important information on the requirements of the earthing conductor, see chapter Earthing and earth
fault protection of the standard.
For the correction factors for each temperature, see International Standard IEC60364-5-52.
