Accumulator
Pressure losses may occur in the piping
downstream of the pressure booster system as a
result of losses due to leakage. The accumulator
serves to compensate for pressure losses and
minimises the frequency of starts of the pressure
booster system.
Certificate of decontamination
A certificate of decontamination is enclosed by the
customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.
Dry running protection

2.8 Unauthorised modes of operation
Always observe the limits stated in the product literature.
The warranty relating to the operating reliability and safety of the pressure booster
system supplied is only valid if the equipment is used in accordance with its intended
use. (ðSection2.2,Page8)
2.9 Electromagnetic compatibility (EMC)
2.9.1 Interference emission requirements
The EN61800-3 EMC product standard is relevant for electric variable speed drives/
control systems. It specifies all pertinent requirements and refers to the relevant
generic standards for complying with the EMC Directive.
Frequency inverters are commonly used by operators as a part of a system, plant or
machine assembly. It should be noted that the operator bears all responsibility for
the final EMC properties of the equipment, plant or installation.
A prerequisite or requirement for complying with the relevant standards or the limit
values and inspection/test levels referenced by them is that all information and
descriptions regarding EMC-compliant installation be observed and followed.
In accordance with the EMC product standard, the EMC requirements to be met
depend on the purpose or intended use of the frequency inverter. Four categories
are defined in the EMC product standard:
Table4: Categories of intended use
CategoryDefinitionLimits to EN55011
C1Frequency inverters with a supply voltage under 1000V installed in the
Class B
first environment (residential and office areas).
C2Frequency inverters with a supply voltage under 1000V installed in the
Class A, Group 1
first environment (residential and office areas) that are neither ready to
be plugged in/connected nor are mobile and must be installed and
commissioned by specialist personnel.
C3Frequency inverters with a supply voltage under 1000V installed in the
Class A, Group 2
second environment (industrial environments).
C4Frequency inverters with a supply voltage over 1000V and a nominal
current over 400A installed in the second environment (industrial

2.9.2 Line harmonics requirements
The product is a device for professional applications as defined by EN 61000-3-2. The
following generic standards apply when establishing a connection to the public
power grid:
▪ EN 61000-3-2
for symmetric, three-phase devices (professional devices with a total power of up
to 1kW)
▪ EN 61000-3-12
for devices with a phase current of between 16A and 75A and professional
devices from 1kW up to a phase current of 16 A.
2.9.3 Interference immunity requirements
In general, the interference immunity requirements for a frequency inverter hinge on
the specific environment in which the inverter is installed.
The requirements for industrial environments are therefore higher than those for
residential and office environments.
The frequency inverter is designed such that the immunity requirements for
industrial environments and, thus, the lower-level requirements for residential and
office environments, are met and fulfilled.
The following relevant generic standards are used for the interference immunity test:
▪ EN 61000-4-2: Electromagnetic compatibility (EMC)
– Part 4-2: Testing and measurement techniques – Electrostatic discharge
immunity test
▪ EN 61000-4-3: Electromagnetic compatibility (EMC)

installations in the set pressure range using one non-self-priming horizontal highpressure pump (7).
The fully automatic pressure booster system pumps the fluid to the consumer
installations in the set pressure range using one or two non-self-priming horizontal
high-pressure pumps (7).
The pump is controlled and monitored by motor-mounted frequency inverters.
The standard setting is for the pressure booster system to start automatically as a
function of pressure; the actual pressure is measured by an analog pressure
measuring device (pressure transmitter).
The use of this variable speed pump significantly reduces wear as well as the
frequency of pump starts in parallel operation.
If a duty pump fails, a fault is output, which can be reported via volt-free contacts
(e.g. to the control station).
If the demand drops towards 0, the pressure booster system slowly runs down to the
stop point and stops.
The pressure booster system is designed with dry running protection.
If the pump has not been in operation for 24 hours, a test run is initiated.
In manual mode, a minimum flow is required to protect the pump against
overheating.
4.6 Noise characteristics

8.2.3 Setting the pre-charge pressure
WARNING
Wrong gas
Danger of poisoning!
▷ Use only nitrogen to charge the accumulator.
CAUTION
Pre-charge pressure too high
Damage to the accumulator!
▷ Observe the manufacturer's product literature (see name plate or operating
manual of the accumulator).
The accumulator’s pre-charge pressure (p) must be lower than the set start-up
pressure (pE) of the pressure booster system.
The best storage volumes are achieved with the following settings (mean value):
▪ Value 0.9 at start-up pressure > 3bar
▪ Value 0.8 at start-up pressure < 3bar
Example 1 pE=5bar
5bar×0.9=4.5bar
With a start-up pressure of 5bar the pre-charge pressure of the accumulator must be
4.5 bar.
Example 2 pE=2bar
2bar ×0.8=1.6bar
With a start-up pressure of 2bar the pre-charge pressure of the accumulator must be
1.6 bar.
Checking the pre-charge pressure
1. Close the shut-off elements fitted underneath the membrane-type accumulator.
2. Drain the membrane-type accumulator via the drain valve.
3. Remove and store the protective cap of the membrane-type accumulator valve.
4. Check the pre-charge pressure using suitable equipment (e.g. tyre pressure
gauge).
5. Fit the protective cap of the membrane-type accumulator valve.
