resulting from this. The individual or company using it bears the sole risk.
Reading these operating instructions and complying with all contained instructions -
especially the safety notifications contained therein - are considered part of intended
use. To consider is also the manual of attached components. Not the manufacturer,
rather the operator of the device is liable for any personal harm or material damage
arising from non-intended use!
2.2 Explanations of symbols
Safety instructions are highlighted with warning triangles and are depicted
according to the degree of hazard as follows.
Attention!
General hazardous area. Death or severe injury or significant property damage can
occur if the corresponding precautions are not taken!
Danger due to electric current
Danger by dangerous, electric voltage! Death or severe injury can occur if the
corresponding precautions are not taken!
Information
Important additional information and advice for user.
2.3 Product safety
The device conforms to the state of the art at the time of delivery and is fundamentally
considered to be reliable. The device and its accessories must only be used in a flawless
condition and installed and operated in compliance with the operating instructions.
Operating outside the device's technical specification (see technical data) can lead to a
defect in the device and additional damage!
2.4 Requirements placed on the personnel / due diligence
Persons entrusted with the planning, installation, commissioning and maintenance and
servicing in connection with the frequency inverter must have the corresponding qual-
ifications and skills for these jobs.
In addition, they must be knowledgeable about the safety regulations, EU/EC directives,
rules for the prevention of accidents and the corresponding national as well as regional

2.5 Start-up and during operation
Attention!
•During commissioning, unexpected and hazardous conditions can arise in the entire
installation due to defective adjustments, defective components or incorrect electrical
connections. Remove all persons and objects from the hazardous area.
•During operation, the device must be closed or installed in a control cabinet. Fuses
may only be replaced by new ones and must not be repaired or bypassed. The data
for the maximum line fuse are to be considered absolutely (see Technical data). Use
only fuses specified in schematic diagrams.
•Any faults detected in the electric system/modules/operating equipment must be
corrected immediately. If these faults are not corrected, the device/system is
potentially very dangerous. The device/system must therefore not be operated when it
is faulty.
•Pay attention to smooth, low vibration running of the motor/fan, the appropriate
instructions in the drive documentation must be observed!
2.6 Work on the device
Information
Mounting, electrical connection, and start-up operation may only be carried out by an
electrical specialist in accordance with electrotechnical regulations (e.g. EN 50110 or
EN 60204)!
Danger due to electric current
It is generally forbidden to carry out work on electrical live parts. Protection class of the
device when open is IP00! It is possible to touch hazardous voltages directly.
The safe isolation from the supply must be checked using a two-pole voltage detector.
2.7 Modifications / interventions in the device
Attention!
For reasons of safety, no unauthorized interventions or modifications may be made on
the device. All planned modifications must be authorized by the manufacturer in writing.
Use only genuine spare parts / genuine wearing parts / genuine accessories from
ZIEHL-ABEGG.These parts were specifically designed for the device. There is no
guarantee that parts from non-original sources are designed and manufactured in
correspondence with load and safety requirements.
Parts and optional equipment not supplied by ZIEHL-ABEGG are not approved by
ZIEHL-ABEGG for use.

storing the controller at room temperature!
5 Electrical installation
5.1 Safety precautions
Danger due to electric current
•Work on electric components may only be carried out by trained electricians or by
persons instructed in electricity under the supervision of an electrician in accordance
with electrical engineering regulations.
•The 5 electrical safety rules must be observed!
•It is forbidden to carry out work on electrically live parts.
•Cover neighbouring electrical equipment during installation work.
•Other measures may be necessary to achieve safe electrical isolation.
•A second person must always be present when working on energized parts or lines
who disconnects in case of emergency.
•Inspect electrical equipment periodically: retighten loose connections – immediately
replace damaged lines and cables.
•Always keep switch cabinets and all electrical supply facilities locked. Access is only
allowed for authorized persons using a key or special tool.
•Operating the device with the housing cover removed is prohibited because
energized, exposed parts are present inside the device. Disregarding this regulation
can lead to severe personal injury.
•The required protective earth connection is established using screws between the
housing parts in metal terminal space covers and housing casings. Commissioning is
only permissible after these screws have been properly attached!
•The device owner is responsible for the EMC of the entire plant according to the
locally applicable standards.
•Metal screwed-connections are not permitted in plastic housing parts because there is
no potential equalization.
•Never clean electrical equipment with water or similar liquids.
Information
The respective connections are represented in the enclosure of this manual (
Connection diagram)!

5. Finally we set the desired nominal speed: Register h2, value 200 (speed value).
Information
•The points 1 - 4 are made only once, register NV (non volatile).
•To change the speed or to write only point 5 must be carried out.
•The internal address is permanently set to 247. If you send an invalid packet, you will
not receive a reply (no changing of input data).
•Please note that if communication to the module is interrupted, then the motor will
behave as follows:
–a/ Watchdog deactivated (h17 0), the motor will continue to turn at the last speed.
–b/ Watchdog activated (e.g. h17 0x0503), the motor will change to the speed
defined in h5. I.e. if h5 0, the motor will stop.
•If communication is re-established, you will see the last values in the input data.

6.7 Communication with ECblue fans
Information
•All examples in this chapter were handled with the MODBUS address 1
•All data with the prefix“0x” are hexadecimal. Example: 0xC8 means C8 hexadecimal
and this corresponds to 200 decimal.
•The counter in the reply MUST NOT be the same counter as in the query. The master
waits for the counter change. The numbers 0x03-0x05 and 0x07-0x09 are only
examples.

Information
For the "Write Double Holding Register" command note whether the Slave MODBUS
devices (e.g. AM-MODBUS) support the command.

The following example (for address 1) shows the setting of an ECblue, setting of
speed to 200 rpm.
1. At first send an empty "dummy" packet to activate the device.
2. Set PIN-Accesslevel to Level 2: Register H0, Value 10 (Level 2).
3. Set the function of D1 to "OFF": Register H14, value 0 (turn off)
4. The we set the control mode: Register H4, value 1 (absolute speed).
5. Finally we set the desired nominal speed: Register H2, value 200 (speed value).
6.7.4 Manual addressing of the MODBUS slave
The individual MODBUS addresses are parameterised directly at the respective slaves.
