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 Smart VFD HVAC 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 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 drive 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 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.

Honeywell • 3
1.2
SAFETY
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 connection 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 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 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 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 conductor 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 mm2 Cu
or 16 mm2 Al through its total run.
b) an automatic disconnection of the supply in case of loss of continuity of the protective
conductor. See chapter 4.
Honeywell • 4
SAFETY
c) provision of an additional terminal for a second protective earthing conductor of the
same cross-sectional area as the original protective earthing conductor.
OR
2. Connection with an industrial connector according to IEC 60309 and a minimum protective earthing connector cross-section of 2.5mm2 as part of a multi-conductor power
cable. Adequate strain relief shall be provided.
NOTE: Due to the high capacitive currents present in the drive, fault current protective switches
may not function properly.
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.
1.4
Running the motor
MOTOR RUN CHECK LIST
Before starting the motor, check that the motor is mounted properly and
ensure that the machine connected to the motor allows the motor to be started.
Set the maximum motor speed (frequency) according to the motor and the
machine connected to it.
Before reversing the motor make sure that this can be done safely.
Make sure that no power correction capacitors are connected to the motor cable.
Make sure that the motor terminals are not connected to mains potential.
NOTE! You can download the English and French product manuals with applicable safety,
warning and caution information from https://customer.honeywell.com/en-US/Pages/default.aspx.

Cable dimensioning and selection
Table 8 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.

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

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.

Table 9. Cable and fuse sizes for Honeywell Smart VFD HVAC (MR7 to MR9)
The cable dimensioning is based on the criteria of the Underwriters’ Laboratories UL508C:Cables must
be PVC-isolated; Max ambient temperature +86°F, max temperature of cable surface +158°F; Use only
cables with concentric copper shield; Max number of parallel cables is 9.
When using cables in parallel, NOTE HOWEVER that the requirements of both the cross-sectional
area and the max number of cables must be observed.
For important information on the requirements of the grounding conductor, see standard Underwriters’
Laboratories UL508C.
For the correction factors for each temperature, see the instructions of standard Underwriters’ Laboratories UL508C.

Cable and motor insulation checks
1. Motor cable insulation checks
Disconnect the motor cable from terminals U, V and W of the drive and from the motor.
Measure the insulation resistance of the motor cable between each phase conductor as
well as between each phase conductor and the protective ground conductor. The insulation resistance must be >1MΩ at ambient temperature of 68°F.
2. Mains cable insulation checks
Disconnect the mains cable from terminals L1, L2 and L3 of the drive and from the mains.
Measure the insulation resistance of the mains cable between each phase conductor as
well as between each phase conductor and the protective ground conductor. The insulation resistance must be >1MΩ at ambient temperature of 68°F.
3. Motor insulation checks
Disconnect the motor cable from the motor and open the bridging connections in the
motor connection box. Measure the insulation resistance of each motor winding. The
measurement voltage must equal at least the motor nominal voltage but not exceed 1000
V. The insulation resistance must be >1MΩ at ambient temperature of 68°F.

Installation in corner-grounded network
Corner grounding is allowed for the drive types rating from 72 A to 310 A at 380...480 V supply
and from 75 A to 310 A at 208...240 V supply.
In these circumstances the EMC protection class must be changed to level C4 following the
instructions in Chapter 5.2 of this manual.
Corner grounding is not allowed for the drive types with rating from 3.4 A to 61 A at 380...480
V supply and 3.7 A to 62 A with 208...240 V supply.

COMMISSIONING
COMMISSIONING
Before commissioning, note the following directions and warnings:
Internal components and circuit boards of the drive (except for the galvanically
isolated I/O terminals) are live when it 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 B-/B+ are live
when the drive is connected to mains, even if the motor is not running.
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.
Do not make any connections to or from the drive when it is connected to the
mains.
After disconnecting the drive from the mains, wait until the fan stops and 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 voltage is present.
Always ensure abscence of voltage before electrical work!
Before connecting the frequency converter to mains make sure that the front
and cable covers of the drive are closed.

Strip about .60 in. of the RS485 cable (see specification on page 57) and cut off
the grey cable shield. Remember to do this for both bus cables (except for the
last device).
Leave no more than .40 in. of the cable outside the terminal block and strip the
cables at about .20 in to fit in the terminals. See picture below.
