3.1 Mechanical Installation

3.1.1 Side-by-side Installation
The drive can be mounted side by side but requires the clearance specified in Table 3 above and below for cooling.
Table 3: Clearance Required for Cooling
N O T I C E
With IP21/NEMA Type1 option kit mounted, a distance of 50 mm (2 in) between the units is required.
Installation
3.1.2 Operating Environment
3.1.2.1 Derating for Ambient Temperature and Switching Frequency
Ensure that the ambient temperature measured over 24 hours is at least 5 °C (9 °F) lower than the maximum ambient temperature that is specified for the drive. If the drive is operated at a high ambient temperature, decrease the constant output current. For derating specifications, see the VLT® Compressor Drive CDS 803 Design Guide listed in
1.2 Additional Resources.
3.1.2.2 Derating for Low Air Pressure and High Altitudes
The cooling capability of air is decreased at low air pressure. For altitudes above 2000 m (6562 ft), contact Danfoss regarding PELV. Below 1000 m (3281 ft) altitude, derating is not necessary. For altitudes above 1000 m (3281 ft), decrease the ambient temperature or the maximum output current. Decrease the output by 1% per 100 m (328 ft) altitude above 1000 m (3281 ft) or reduce the maxi­mum ambient cooling air temperature by 1 °C (1.8 °F) per 200 m (656 ft).

3.2 Electrical Installation

Installation
3.2.5 EMC-compliant Electrical Installation
To obtain an EMC-compliant installation, be sure to follow all electrical installation instructions. Also, remember to practice the fol­lowing:
When using relays, control cables, a signal interface, fieldbus, or brake, connect the shield to the enclosure at both ends. If the ground path has high impedance, is noisy, or is carrying current, break the shield connection on 1 end to avoid ground current loops.
Convey the currents back to the unit using a metal mounting plate. Ensure good electrical contact from the mounting plate by securely fastening the mounting screws to the drive chassis.
Use shielded cables for motor output cables. An alternative is unshielded motor cables within metal conduit.
Ensure that motor and brake cables are as short as possible to reduce the interference level from the entire system.
Avoid placing cables with a sensitive signal level alongside motor and brake cables.
For communication and command/control lines, follow the particular communication protocol standards. For example, USB must use shielded cables, but RS485/ethernet can use shielded UTP or unshielded UTP cables.
Ensure that all control terminal connections are rated protective extra low voltage (PELV).
N O T I C E
TWISTED SHIELD ENDS (PIGTAILS)
Twisted shield ends increase shield impedance at higher frequencies, which increases the leakage current.
Use integrated shield clamps instead of twisted shield ends.
-
N O T I C E
SHIELDED CABLES
If shielded cables or metal conduits are not used, the unit and the installation do not meet regulatory limits on radio frequency
(RF) emission levels.
N O T I C E
EMC INTERFERENCE
Failure to isolate power, motor, and control cables can result in unintended behavior or reduced performance.
Use shielded cables for motor and control wiring.
-
Provide a minimum 200 mm (7.9 in) separation between mains input, motor cables, and control cables.

5 Troubleshooting

5.1 Acoustic Noise or Vibration

If the compressor application makes noise or vibrations at certain frequencies, adjust the following parameters to avoid resonance problems within the system.
Upper and lower frequency limits, Parameter group 4-6* Speed Bypass.
Switching pattern and switching frequency, parameter group 14-0* Inverter Switching.

5.2 Warnings and Alarms

A warning or an alarm is signaled by the relevant indicator on the front of the drive and indicated by a code on the display. A warning remains active until its cause is no longer present. Under certain circumstances, operation of the compressor may still be
continued. Warning messages may be critical. In the event of an alarm, the drive has tripped. To restart operation, reset alarms once their cause has been rectified.
This may be done in 4 ways:
By pressing [Reset].
Via a digital input with the Reset function.
Via serial communication.
By resetting automatically using the [Auto Reset] function, see parameter 14-20 Reset Mode.
A trip is the action following an alarm. The trip coasts the compressor and is reset by pressing [Reset] or by a digital input (parameter group 5-1* Digital Inputs). The original event that caused an alarm cannot damage the drive or cause dangerous conditions. A trip lock is an action when an alarm occurs, which could damage the drive or connected parts. A trip lock situation can only be reset by cycling power.
Refer to the VLT® Compressor Drive CDS 803 Programming Guide listed in gramming.
1.2 Additional Resources for parameter details and pro-
Table 10: Indicator Lights
The alarm words, warning words and extended status words can be read out via serial bus or optional fieldbus for diagnosis. See also parameter 16-90 Alarm Word, parameter 16-92 Warning Word, and parameter 16-94 Ext. Status Word.
N O T I C E
MOTOR RESTART
After a manual reset pressing [Reset], press [Auto On] or [Hand On] to restart the motor.
If an alarm cannot be reset, the reason may be that its cause has not been rectified, or the alarm is trip-locked, see Table 11.
C A U T I O N
ALARM RESET
Alarms that are trip-locked offer extra protection, meaning that the mains supply must be switched off before the alarm can be
reset. After being switched back on, the drive is no longer blocked and may be reset as described above once the cause has been
rectified.
Alarms that are not trip-locked can also be reset using the automatic reset function in parameter 14-20 Reset Mode (Warning: auto-

In addition, a high-power factor indicates that the different harmonic cur­rents are low.
The DC coils in the drive produce a high-power factor, which minimizes the imposed load on the mains supply.
Preset reference
A defined preset reference to be set from -100% to +100% of the reference range. Selection of 8 preset references via the digital terminals.

RCD
Residual-current device.
Relay outputs
The drive features 2 programmable relay outputs.
Set-up
Save parameter settings in 4 set-ups. Change between the 4 parameter set­ups and edit 1 set-up, while another set-up is active.
Slip compensation
The drive compensates for the compressor slip by giving the frequency a supplement that follows the measured compressor load keeping the com­pressor speed almost constant.
Start-disable command
A stop command belonging to Group 1 control commands, see the table Function Groups under Control Command.
Stop command
A stop command belonging to Group 1 control commands, see the table Function Groups under Control Command.
Thermistor
A temperature-dependent resistor placed on the drive or the compressor.
Trip
A state entered in fault situations, for example, if the drive is subject to an overtemperature or when the drive is protecting the compressor, process, or mechanism. The drive prevents a restart until the cause of the fault has disappeared. To cancel the trip state, restart the drive. Do not use the trip state for personal safety.
Trip lock
The drive enters this state in fault situations to protect itself. The drive re­quires physical intervention, for example when there is a short circuit on the output. A trip lock can only be canceled by disconnecting mains, re­moving the cause of the fault, and reconnecting the drive. Restart is preven­ted until the trip state is canceled by activating reset or, sometimes, by be­ing programmed to reset automatically. Do not use the trip lock state for personal safety.
