1 Regarding this Document
1.1 Using this document
This document, hereafter called the service manual, contains important information about all life
phases of the machine.
The operating manual is a component of the product. It describes the machine as it was at the time
of first delivery after manufacture.
➤ Keep the service manual in a safe place throughout the life of the machine.
➤ Supply any successive owner or user with this service manual.
➤ Please insert any amendment or revision of the service manual sent to you.
➤ Enter details from the machine nameplate and individual items of equipment in the table in
chapter 2.
1.2 Further documents
Included with this operating manual are additional documents intended to assist in the safe opera‐
tion of the machine:
■ Manufacturer's/installation declaration according to applicable directives
■ Motor manual
Missing documents can be requested from KAESER.
➤ Make sure all documents are complete and observe the instructions contained in them.
➤ Make sure you provide the data from the nameplate when ordering documents.
1.3 Copyright
This operator manual is copyright protected. Queries regarding use or duplication of the documen‐
tation should be referred to KAESER. Correct use of information will be fully supported.
1.4 Symbols and labels
➤ Please note the symbols and labels used in this document.
1.4.1 Warnings
Warnings indicate danger potentially resulting in personal injury, if the measures specified are not
taken.
Warnings indicate three levels of danger identified by the corresponding signal word:
Signal term Meaning Consequences of non-compliance
DANGER Warns of imminent danger Will very likely result in death or severe injury
WARNING Warns of potentially imminent danger May result in death or severe injury
CAUTION Warns of a potentially dangerous situa‐
tion
May result in moderate physical injury

Warning notes may precede a chapter. They apply to the entire chapter including all sub-sections.
Example:
The type and source of the imminent danger is shown here!
The possible consequences of ignoring a warning are shown here.
The word "DANGER" indicates that death or severe injury can very likely result from ignoring
the warning.
➤ The measures required to protect yourself from danger are shown here.
Warning notes referring to a sub-section or the subsequent step are integrated into the procedure
and numbered as a step.
Example:
1.
The type and source of the imminent danger is shown here!
The possible consequences of ignoring a warning are shown here.
The word "WARNING" indicates that death or severe injury may result from ignoring the warn‐
ing.
➤ The measures required to protect yourself from danger are shown here.
2. Always read and comply with warning instructions.
1.4.2 Potential damage warnings
Contrary to the warnings shown above, damage warnings do not indicate potential personal injury.
Damage warnings have only one danger level, identified by this signal word:
Signal term Meaning Consequences of non-compliance
NOTE Warns of a potentially dangerous situation Damage to property is possible
Tab. 2 Danger levels and their definition (damage to property)
Example:
The type and source of the imminent danger is shown here!
Potential effects when ignoring the warning are indicated here.
➤ The protective measures against the damages are shown here.
➤ Carefully read and fully comply with warnings against damages.

■ Sound insulated pipeline
Further information The sound pressure level and sound power level values for your machine are provided in the ta‐
bles shown in chapter 13.4.
These values refer to the design condition.
2.12 Power Supply
Basic requirements
The machine is designed for an electrical supply according to National Electric Code (NEC), edi‐
tion 2017, particularly article 670 and NFPA 79, edition 2015, particularly section 4.3. In the ab‐
sence of any user-specified alternatives, the limits given in these standards must be adhered to.
Consult manufacturer for any other specific power supply.
The incoming line within the control panel should be as short as possible.
If external sensors or communication lines are to be connected to the machine, use shielded ca‐
bles and insert the same through EMC fittings into the control panel.
Three-phase
Do NOT operate package on any unsymmetrical power supply. Also do NOT operate package on
power supplies such as a three phase WYE system with center point not solidly grounded or three-
phase (open) delta.

The machine requires a symmetrical three-phase power supply transformer with a WYE configura‐
tion output as shown in Figure 1 and Figure 2. In a symmetrical three phase supply the phase an‐
gles and voltages are all the same.
Other power supplies are not suitable.
Fig. 1 Three-phase star (wye); 4 wire; center point solidly grounded
Fig. 2 Three-phase star (wye); 3 wire; center point solidly grounded
Further information Please contact an authorized KAESER service representative for options.
The electrical diagram 13.5 contains further specifications for electrical connection.
2.13 Power supply specifications
The following multi-strand copper core wires are given according to 2017 NEC 310.1, Table
310.15(B)(16) for 40 °C ambient temperature.
If other local conditions prevail, like for example high temperature, the cross section should be
checked and adjusted according to 2017 NEC 110.14(C), 220.3, 310.15, Table 310.15(B)(2)(a),
430.6,430.22, 430.24, 670.4(A) and other local codes.
Dual element time delay fuses are selected according to 2017 NEC 240.6 , 430.52 and tables
430.52, 430.248 and 430.250.
We strongly suggest using a separate copper conductor for the equipment GROUNDING. 2017
NEC Table 250.122 will point out the “minimum size”, however, we recommend a ground conduc‐
tor the same size as the power leads, if local codes allow.
