1 SAFETY

Please read the information included in cautions and warnings carefully:
CAUTION
ONLY A COMPETENT ELECTRICIAN IS ALLOWED TO CARRY OUT THE ELECTRICAL INSTALLATION!
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.
Application manual HVAC232/402 | Document 27-652 | Issue ENG06 | 2019-08-07 6

1.1 Warnings

WARNING
The components of the power unit of the frequency converter are live when HVAC232/402 is connected to mains. Coming into contact with this voltage is extremely dangerous and may cause death or severe injury. The control unit is isolated from the mains potential.
WARNING
The motor terminals U, V, W (T1, T2, T3) and the possible brake resistor terminals / + are live when HVAC232/402 is connected to mains, even if the motor is not running.
WARNING
The control I/O-terminals are isolated from the mains potential. However, the relay output terminals may have a dangerous control voltage present even when HVAC232/402 is disconnected from mains.
WARNING
If the frequency converter is used as a part of a machine, the machine manufacturer is responsible for providing the machine with a main switch (EN 602041).
WARNING
If HVAC232/402 is disconnected from mains while running the motor, it remains live if the motor is energized by the process. In this case the motor functions as a generator feeding energy to the frequency converter.
WARNING
After disconnecting the frequency converter from the mains, wait until the fan stops and the indicators on the display go out. Wait 5 more minutes before doing any work on HVAC232/402 connections.
WARNING
The earth leakage current of HVAC232/402 frequency converters exceeds 3.5 mA AC. According to standard EN61800 51, a reinforced protective ground connection must be ensured.
Application manual HVAC232/402 | Document 27-652 | Issue ENG06 | 2019-08-07 7
WARNING
The motor can start automatically after a fault situation, if the autoreset function has been activated.

1.2 Safety instructions

CAUTION
The HVAC232/402 frequency converter has been designed for fixed installations only.
CAUTION
Do not perform any measurements when the frequency converter is connected to the mains.
CAUTION
Do not perform any voltage withstand tests on any part of HVAC232/4 02. The product safety is fully tested at factory.
CAUTION
Prior to measurements on the motor or the motor cable, disconnect the motor cable from the frequency converter.
CAUTION
Do not open the cover of HVAC232/402. Static voltage discharge from your fingers may damage the components. Opening the cover may also damage the device. If the cover of HVAC232/402 is opened, warranty becomes void.

1.3 Earthing and earth fault protection

MCR36497
MCR36498
The Smart HVAC232/402 frequency converter must always be earthed with an earthing conductor connected to the earthing terminal. See figure below:
MCR36496
Fig. 2. MI4
Fig. 1. MI1 - MI3
Fig. 3. MI5
1. The earth fault protection inside the frequency converter protects only the converter itself against earth faults.
2. If residual current devices are used they must be tested with the drive with earth fault currents that are possible to arise in fault situations.
Application manual HVAC232/402 | Document 27-652 | Issue ENG06 | 2019-08-07 9

1.4 Before running the motor

2.2 Maintenance

Checklist:

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 shaft rotation direction make sure that this can be done safely.

Make sure that no power correction capacitors are connected to the motor cable.

2 RECEIPT OF DELIVERY

After unpacking the product, check that no signs of transport damages are to be found on the product and that the delivery is complete (compare the type designation of the product to the code: see chapter 12).
Should the drive have been damaged during the shipping, please contact primarily the cargo insurance company or the carrier.
In normal operating conditions, HVAC232/402 frequency converters are maintenance- free. However, regular maintenance is recommended to ensure a trouble-free operating and along lifetime of the drive. We recom­mended to follow the table below for maintenance intervals.
Table 1.
Maintenance interval Maintenance action
Whenever necessary Clean heat sink* Regular Check tightening torques of terminals 12 months (If stored) Check input and output terminals and control
I/O terminals. Clean cooling tunnel.* Check operation of cooling fan. Check for corrosion on terminals, bus bars
and other surfaces.*

• Main fan*
• Internal fan*
If the delivery does not correspond to your order, contact the supplier imme­diately.

2.1 Storage

If the frequency converter is to be kept in store before use make sure that the ambient conditions are acceptable:
Storing temperature –40 °F (–40 °C)…+70 °F (21 °C) Relative humidity < 95%, no condensation
Application manual HVAC232/402 | Document 27-652 | Issue ENG06 | 2019-08-07 10
Capacitor recharge
M36500
After a longer storage time the capacitors need to be recharge in order to avoid capacitor damage. Possible high leakage current through the capac­itors must be limited. The best way to achieve this is to use a DC-power supply with adjustable current limit.
1. Set the current limit to 300…800 mA according to the size of the drive.
2. Then connect the DC-power supply to the input phase L1 and L2.

3 INSTALLATION

3.1 Mechanical installation

There are two possible ways to mount HVAC232/402 in the wall. For MI1MI3, either screw or DIN-rail mounting; For MI4MI5, screw or flange mounting.
3. Then set the DC-voltage to the nominal DC voltage level of the (1.35 × Un AC) and supply the converter for at least 1h.If DC-voltage is not available and the unit has been stored much longer than 12 months de-energized, consult the factory before connecting power.

2.3 Warranty

Only manufacturing defects are covered by the warranty. The manufacturer assumes no responsibility for damages caused during or resulting from transport, receipt of the delivery, installation, commissioning or use.
The manufacturer shall in no event and under no circumstances be held responsible for damages and failures resulting from misuse, wrong installation, unacceptable ambient temperature, dust, corrosive substances or operation outside the rated specifications. Neither can the manufacturer be held responsible for consequential damages.
Variable frequency drive devices (VFD) and accessories: new products for thirty-six (30) months from the date of production.

3.5 EMC levels

EN618003 defines the division of frequency converters into four classes according to the level 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: Frequency converters of this class comply with the re-
quirements of category C1of the product standard EN 618003(2004). Category C1 ensures the best EMC characteristics and it includes converters the rated voltage of which is less than 1000 V and which are intended for use in the 1st environ­ment.
NOTE:
The requirements of class C are fulfilled only as far as the conducted emissions are concerned.
Category C4: The drives of this class do not provide EMC emission protec-
tion. These kinds of drives are mounted in enclosures.
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.
Category C2: Frequency converters of this class comply with the re-
quirements of category C2of the product standard EN 618003(2004). Category C2 includes converters in fixed installations and the rated voltage of which is less than 1000 V. The class C2 frequency converters can be used both in the 1st and the 2nd environment.
Application manual HVAC232/402 | Document 27-652 | Issue ENG06 | 2019-08-07 21
Second environment: Environment that includes all establishments oth-
er 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.

3.6 Changing the EMC protection class from C2 to C4

The EMC protection class of MI13 frequency converters can be changed from class C2 to class figure below. MI4 & 5 can also be changed by removing the EMC jumpers.
NOTE:
Do not attempt to change the EMC level back to class C2. Even if the procedure above is reversed, the frequency converter will no longer fulfil the EMC requirements of class C2!

Cable and fuse specifications
Use cables with heat resistance of at least 158 °F (70 °C). The cables and the fuses must be dimensioned according to the tables below.
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.
Installation of cables is presented in chapter „3.10 Cable installation“ on page 32.
The fuses function also as cable overload protection. The recommended fuse types are gG/gL (IEC 602691). 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 should not be used.
Table 7. Cable types required to meet standards.
EMC categories are described in Chapter „3.5 EMC levels“ on page 21.

Consult the factory about faster fuses.
Honeywell offers recommendations also for aR (IEC 602694) and gS (IEC 602694) fuse ranges.
These instructions apply only to cases with one motor and one cable con­nection from the frequency converter to the motor. In any other case, ask the factory for more information.
