serious injury.

Stop the motor.

-

Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and

-

DC-link connections to other drives.

Wait for the capacitors to discharge fully. The minimum waiting time is specified in the table Discharge time and is also visible

-

on the nameplate on the top of the drive.

Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors

-

are fully discharged.

Product Overview

3.3 Check Valve Monitoring

In the pump application system, a damaged check valve is hard to detect, which therefore causes low efficiency of the whole sys­tem. VLT® Flow Drive FC 111 can monitor the status of check valves in the system. After enabling the check valve monitoring func­tion via setting parameter 22-04 Check Valve Monitor to [1] Enabled, the drive trips warning 159, Check Valve Failure if a damaged
check valve is detected.

3.4 Dry Pump Detection

In the pump application system, the drive monitors the operation status of the system to detect whether there is water on the
pump's suction side. If the pump runs at maximum speed and consumes little power, then it can be assumed that there is no water
on the pump's suction side. Via setting parameter 22-26 Dry Pump Function to warning or alarm, the drive trips warning/alarm 93, dry
pump if the dry-pump condition is detected.

3.5 End of Curve Detection

In the pump application system, the drive monitors the operation status of the system to detect whether the pressure side of pump
is subject to a major leakage. If the pump runs at maximum speed for a defined time period, but the pressure is below the set point,
then it can be considered to reflect the end-of-curve situation. Via setting parameter 22-50 End of Curve Function to warning or
alarm, the drive trips warning/alarm 94, end of curve if the end-of-curve condition is detected.

3.6 Time-based Functions

In some application scenarios, there are requirements to control the motor running for a specific time, in a specific direction and a
specific speed within a specific time interval. For example, checking the motor status in fire mode or exercising pumps, fans, and
compressors.

For detailed parameter settings, refer to the parameter group 23-** Time-based Functions in the drive's Programming Guide.

In environments with airborne liquids, particles, or corrosive gases, failure to meet requirements for ambient conditions can re-

duce the lifetime of the drive.

Ensure that the IP/Type rating of the equipment matches the installation environment.

-

Ensure that requirements for air humidity, temperature, and altitude are met.

-

Table 6: Installation at High Altitudes

N O T I C E

CONDENSATION

Moisture can condense on the electronic components and cause short circuits.

Avoid installation in areas subject to frost.

-

Install an optional space heater when the drive is colder than the ambient air.

-

Operating in standby mode reduces the risk of condensation as long as the power dissipation keeps the circuitry free of

-

moisture.

N O T I C E

EXTREME AMBIENT CONDITIONS

Hot or cold temperatures compromise unit performance and longevity.

Do not operate in environments where the ambient temperature exceeds 55 °C (131 °F).

-

The drive can operate at temperatures down to -15 °C (5 °F). However, proper operation at rated load is only guaranteed at

-

0 °C (32 °F) or higher.

Extra air conditioning of the cabinet or installation site is required if temperature exceeds ambient temperature limits.

-

W A R N I N G

EXPLOSIVE ATMOSPHERE

Do not install the drive in a potentially explosive atmosphere.

Install the unit in a cabinet outside of this area.

-

Failure to follow this guideline increases risk of death or serious injury.

N O T I C E

GASES

Aggressive gases, such as hydrogen sulfide, chlorine, or ammonia can damage the electrical and mechanical components.

The unit uses conformal-coated circuit boards to reduce the effects of aggressive gases.

-

When installing the drive in dusty environments, pay attention to the following:

Periodic maintenance

When dust accumulates on electronic components, it acts as a layer of insulation. This layer reduces the cooling capacity of the
components, and the components become warmer. The hotter environment decreases the life of the electronic components. Keep
the heat sink and fans free from dust build-up.

Cooling fans

Fans provide airflow to cool the drive. When fans are exposed to dusty environments, the dust can damage the fan bearings and
cause premature fan failure. Also, dust can accumulate on fan blades causing an imbalance which prevents the fans from properly
cooling the unit.

4.2 Side-by-side Installation

The drive can be mounted side by side but requires the clearance above and below for cooling.

Table 7: Clearance Required for Cooling

With IP21 option kit mounted (available for H1–H5 & H11–H12), a distance of 50 mm (2 in) between the units is required.

4.4 Installation and Cooling Requirements

OVERHEATING

Improper mounting can result in overheating and reduced performance.

Install the drive according to the installation and cooling requirements.

-

Installation requirements

•

Ensure drive stability by mounting the drive vertically to a solid flat surface.

•

Ensure that the strength of the mounting location supports the drive weight. Ensure that the mounting location allows access
to open the enclosure door. Refer to 3.2 Power Ratings, Weights, and Dimensions.

•

Ensure that there is enough space around the drive for cooling airflow.

•

Place the drive as near to the motor as possible. Keep the motor cables as short as possible. See 10.4.4 Cable Length and Cross-

section.

•

Ensure the location allows for cable entry at the bottom of the drive.

Cooling and airflow requirements

•

Ensure that top and bottom clearance for air cooling is provided, see 4.2 Side-by-side Installation.

•

Consider derating for temperatures starting between 40 °C (104 °F) and 55 °C (131 °F) and elevation 1000 m (3300 ft) above sea
level. See chapter Derating in the Design Guide for detailed information.

•

The drive's maximum heating value could be estimated via the following equation:

Maximumheatingvalue ≈ Power × 1 − Efficiency

For example, the heating value of 110 kW (150 hp) drive could be 2.2 kW. Refer to 10.1.1 3x380–480 V AC for the drive's efficien­cy at rated load.

•

If multiple drives are installed in 1 cabinet at the same time, the heating value and ventilation volume shall be accumulated.

Operating Guide

••If there are other heating devices, increase the ventilation according to the instructions.

If the dust screen needs to be installed, the air volume needs to be appropriately increased according to the wind resistance
coefficient of the dust screen. For the wind resistance coefficient of dust screen, contact the dust screen supplier.

4.5 Lifting the Drive

W A R N I N G

HEAVY LOAD

Unbalanced loads can fall or tip over. Failure to take proper lifting precautions increases risk of death, serious injury, or equip-

ment damage.

Move the unit using a hoist, crane, forklift, or other lifting device with the appropriate weight rating. See 3.2 Power Ratings,

-

Weights, and Dimensions for the weight of the drive.

Failure to locate the center of gravity and correctly position the load can cause unexpected shifting during lifting and trans-

-

port. For measurements and center of gravity, see 3.2 Power Ratings, Weights, and Dimensions.

The angle from the top of the drive module to the lifting cables affects the maximum load force on the cable. This angle

-

must be 65° or greater. Refer to the following illustration. Attach and dimension the lifting cables properly.

Never walk under suspended loads.

-

To guard against injury, wear personal protective equipment such as gloves, safety glasses, and safety shoes.

-

Always lift the drive using the dedicated eye bolts at the top of the drive. See the following illustration.

Illustration 10: Lifting the Drive

4.6 Wall Mounting the Drive

H13 and H14 are chassis drives intended to be mounted on a wall or on a mounting plate within an enclosure. To wall mount the
drive, use the following steps.

Procedure

1.

Fasten 2 M10 bolts in the wall to align with the fastener slots at the bottom of drive.

2.

Slide the lower fastener slots in the drive over the M10 bolts.
