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
1.1.2 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
3.2.1 Electrical Installation in General
All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. Copper conductors
are required. 75 °C (167 °F) is recommended.
3.2.1.1 Fastener Torque Ratings
Table 4: Tightening Torques for Enclosure Sizes H3–H6, 3x200–240 V & 3x380–480 V
Fuses and circuit breakers ensure that possible damage to the drive is limited to damage inside the unit. Danfoss recommends fuses
on the supply side as protection. For further information, see the application note Fuses and Circuit Breakers found on www.dan-
foss.com under Service and support/Documentation/Manuals & guides.
N O T I C E
Use of fuses on the supply side is mandatory for IEC 60364 (CE) and NEC 2009 (UL) compliant installations.
3.2.2.1 Recommendation of Fuses and Circuit Breakers
Table 5: Fuses and Circuit Breakers
1
Circuit breakers have not been evaluated by Danfoss as part of the certification process.
3.2.3.4 Connecting to Mains and Compressor Terminals
•
Tighten all terminals in accordance with the information provided in 1.3.2.1.1 Fastener Torque Ratings.
•
Keep the compressor cable as short as possible to reduce the noise level and leakage currents.
•
Use a shielded/armored compressor cable to comply with the EMC emission specifications and connect this cable to both the
decoupling plate and the compressor. Also see 1.3.2.5 EMC-compliant Electrical Installation.
1.
Connect the ground cable to the ground terminal, then connect the mains supply to terminals L1, L2, and L3.
Remove the terminal cover to access the control terminals.
Use a flat-edged screwdriver to push down the lock lever of the terminal cover under the LCP, then remove the terminal cover as
shown in the following illustration.
Illustration 5: Removing the Terminal Cover
The following illustration shows all the drive control terminals. Applying start (terminal 18), connection between terminals 12-27,
and an analog reference (terminal 53 or 54, and 55) make the drive run.
The digital input mode of terminal 18, 19, 27, and 29 is set in parameter 5-00 Digital Input Mode (PNP is default value).
RS485 is a 2-wire bus interface compatible with multi-drop network topology. This interface contains the following features:
•
Ability to select from the following communication protocols:
-

sources.
Example
Illustration 7: RS485 Wiring Connection
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.

ler (PLC).
Adjust the speed reference throughout the speed range.
3.
Ensure that the system is working as intended by checking the sound and vibration levels of the compressor.
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 (parametergroup 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.
