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
1.1.2 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

3.2.5 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.

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: auto­matic wake-up is possible!) alarm for a given fault.

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.

操作指南
3.2.5 符合 EMC 规范的电气安装
要使安装符合 EMC 规范,请确保遵循所有电气安装说明。此外,谨记遵循以下做法:
使用继电器、控制电缆、信号接口、现场总线或制动时,在机箱两端连接屏蔽。如果接地通路的阻抗高、噪声高或带电, 则在一端断开屏蔽连接以避免形成接地电流回路。
使用金属安装板将电流传送回设备。牢靠地将安装螺钉固定到变频器机架上,确保安装板保持良好的电气接触。
对电机输出电缆使用屏蔽电缆。或者在金属线管内使用非屏蔽电机电缆。
确保电机和制动电缆尽可能短,以降低整个系统的干扰水平。
不要将带有敏感信号电平的电缆与电动机电缆和制动电缆放在一起。
对于通讯和命令/控制线路,请遵循特定通讯协议标准。例如,USB 必须使用屏蔽电缆,但 RS485/以太网可以使用屏蔽 UTP 或非屏蔽 UTP 电缆。
确保所有控制端子连接都符合保护性超低压 (PELV) 要求。
注 意
双绞线屏蔽端部(辫状) 双绞线屏蔽端部会增加高频下的阻抗,从而增大泄漏电流。
使用集成的屏蔽夹而不是将屏蔽丝网端部扭结。
-
安装
注 意
屏蔽电缆 如果未使用屏蔽电缆或金属线管,则设备和系统不符合有关射频 (RF) 辐射水平的法规限制。
注 意
EMC 干扰 如果未隔离电源、电机和控制电缆,将可能导致意外操作或降低性能。
对电机和控制接线使用屏蔽电缆。
-
主电源输入、电机电缆和控制电缆之间的间隙至少应为 200 毫米(7.9 英寸)。
-
注 意
EMI/EMC 不合规 非 Danfoss 安装的面板组件将使 EMI/EMC 合规性和其他认证失效。
注 意
安装在高海拔下 存在过压风险。组件和关键零件之间的绝缘不充分,可能不符合 PELV 要求。
使用外部保护设备或电隔离装置。在海拔超过 2000 米(6500 英尺)的位置安装时,请联系 Danfoss 了解保护性超低压
-
(PELV) 合规事宜。
保护性超低压 (PELV) 合规 使用 PELV 电源并遵守地方和国家 PELV 法规来防止电击。

5.1 声源性噪音或振动
如果压缩机在特定频率下发出噪音或出现振动,请调整以下参数以避免系统出现共振问题。
频率上限和下限,参数组 4-6* 速度旁路。
在参数组 14-0* Inverter Switching (逆变器开关)中更改模式和开关频率。
5.2 警告和报警
报警或警告是通过变频器前方的相关指示灯发出信号,并在显示器上以代码的形式进行指示。 警告保持活动状态,直至其产生原因不复存在。在某些情况下,压缩机可能仍会继续运行。警告消息可能很重要。 发生报警事件时,变频器将跳闸。要重新运行,修正报警产生的原因后复位报警。 可通过 4 种方式实现:
通过点按 [Reset](复位)。
通过具有复位功能的数字输入。
通过串行通讯。
通过使用 [Auto Reset](自动复位)功能进行复位,请参阅。参数 14-20 Reset Mode(复位模式)。
出现报警时将跳闸。跳闸会使压缩机惯性停车,通过点按 [Reset](复位)或使用数字输入(参数组 5-1* Digital Inputs (数字输 入))复位。导致报警的起源事件不会损害变频器或造成危险情况。当发生可能损害变频器或相连部件的报警时,系统将执行跳 闸锁定操作。跳闸锁定情况只能通过电源循环来复位。
有关参数详细信息和编程,请参阅
1.1.2 其他资源中列出的 VLT® Compressor Drive CDS 803 编程指南。

借助串行总线或选配的现场总线可以读取报警字、警告字和扩展状态字来进行诊断。另请参阅参数 16-90 Alarm Word(报警 字)、参数 16-92 Warning Word(警告字)和参数 16-94 Ext. Status Word(扩展状态字)。
注 意
电机重启 按 [Reset](复位)手动复位后,按 [Auto On](自动启动)或 [Hand On](手动启动)以重新启动电机。
如果无法将报警复位,可能是由于其产生原因尚未得到修正,或者是由于该报警被跳闸锁定了,请参阅 26
注 意
报警复位 跳闸锁定型报警具有附加保护,这表示在复位该报警前必须关闭主电源。重新开启主电源后,变频器将不再受阻,可以在修 正其产生原因后按上述方法复位。 跳闸锁定型报警也可以使用参数 14-20 Reset Mode(复位模式)中的自动复位功能来复位(警告:此时可能自动唤醒!)
