Cooling water quality
Requirements for and care of the water in the cooling circuits!
Depending on the type of the system to be cooled, the cooling water must meet certain
requirements regarding its quality. In order to protect the system parts from corrosion and
deposits, Muegge GmbH on principle recommends that the water in closed circuits be treated
with a suitable agent (corrosion protection with non-ferrous metal protection and hardness
stabilisation). Moreover, in both open and closed circuits the following water qualities must be
observed subject to the materials installed, the temperature and the procedure.

211CV.
Hazards exist:
For life and limb of the operator
For the MH3000S-211CV and other material assets
Therefore it is required that all activities in connection with the MH3000S-211CV be carried
out by trained personnel in accordance with the information contained within these operating
instructions. The technical data must be observed as a matter of principle.
3.2 Responsibility
Areas of responsibility of Roth & Rau Muegge GmbH
Roth & Rau Muegge GmbH is responsible for the safety of the MH3000S-211CV. This is
based on the presupposition that the MH3000S-211CV has not been modified in any way
following the final acceptance.
Operator's areas of responsibility
The operator is responsible for the safety in the area surrounding the MH3000S-211CV.
Moreover, it is the operator's responsibility to ensure that the general safety regulations are
complied with for all works on the MH3000S-211CV.

HAZARD marks an immediate hazard with high risk which will
result in death or severe physical injury if not avoided.
CAUTION
CAUTION marks a potential hazard with medium risk which may
result in death or severe physical injury if not avoided.
ATTENTION
ATTENTION marks a hazard with low risk which might result in
minor or medium-grade physical injury or damage to property if not
avoided.
NOTE
A note such as this one points to particularly important, however
not immediately hazardous information.

3.3.3 Threshold values for the microwave stray radiation
According to current knowledge and until the completion of the research currently being
conducted in several countries, the microwave stray radiation density must not exceed 50
Wm-2 (5mWcm-2)at a distance of 0.05m from any accessible system part under normal
operating conditions.
Moreover, the power density of 100Wm-2 at a distance of 0.05m from any accessible point
of the system part must not be exceeded under conditions referred to as "exceptional
operation".
HAZARD
Persons must not be exposed to microwave energy radiated by
the microwave generator.
3.3.4 Improper use
Any use of the MH3000S-211CV deviating from the uses described in 2.1 and 2.2 is
prohibited. Improper use may result in hazards.
3.3.5 Service and maintenance works
All works on the MH3000S-211CV may only be carried out by persons who, based on their
technical qualifications, knowledge and professional experience, as well as knowledge of the
relevant regulations, are able to assess and execute the work to be performed and are able to
recognize the potential risks.
For any type of work the following principle must absolutely be observed:
ONLY WORK ON A SYSTEM THAT HAS BEEN DISCONNECTED FROM THE MAINS
In order to ensure proper disconnection from the mains, the following safety regulations must
be observed.
Disconnect from the mains
Secure against restarting
Ensure that the system has been properly disconnected
Earth and short-circuit
Cover or make inaccessible nearby live parts
3.3.6 Modifications
Any modifications require the written consent of the manufacturer.

3.3.7 Interlock
The safety of systems of this application class is based on the principle of single-error safety.
In other words, if an error occurs, the safe condition must persist and the system turns off.
Microwave systems are equipped with at least two safety circuits working independently of
each other which allow for dual-channel monitoring.
In accordance with standard EN 60519-6, the following applies, among other things:
"When clearing an access opening of the microwave heating system, at least two microwave
interlocking devices (interlocking switch) of the microwave system must be activated with
elevated safety requirements and high reliability.
The failure of a mechanical or electrical interlocking device on access openings must set off
an alarm and deactivate the microwave system.
The failure of an electrical or mechanical component must not lead to all interlocking devices
for the access openings becoming ineffective.
At each opening, at least one microwave interlocking device must be covertly placed in such a
way that it cannot be operated with the aid of a human body part, neither during the open,
closed nor any intermediate position of the access opening."

The MH3000S-211CV is delivered on a conventional Euro pallet. The dimensions of the
MH3000S-211CV are LxWxH 550x200x395mm, and its weight is 14.5kg. The magnetron
head is initially wrapped in bubble wrap and packed in a transport box. Moreover, each edge
is equipped with an edge protector, and the transport box is strapped to the pallet with steel
straps.
The MH3000S-211CV is stored under specific conditions defined in Chapter 2.8.
4.2 Unpacking
First loosen the steel straps and then remove the edge protection and the bubble wrap.
The packaging material consists of metal, plastic and cardboard and must be disposed of
according to the applicable regulations.
4.3 Safety precautions prior to use
Ensure that the MH3000S-211CV is properly installed in the MW Power Supply Cabinets.

4.5 Installation and assembly
The assembly of the MW Power Supply may only be carried out by qualified personnel.
Magnetron heads and their waveguides and / or coaxial conductors must be tightly bolted
together with the application. No leakage radiation must escape to the outside! (Chapter
Security)
After having checked the tight fitting of the magnetron heads, the cooling of the devices must
first be ensured.
In the case of air-cooled devices (magnetron heads / power supplies) cooling (insofar as no
other information is given) is effected internally via ventilators!
In the case of water-cooled devices (magnetron heads / power supplies) the water circuit must
be set up! The water inlet is marked IN and the water outlet is marked OUT. The required
amount for this purpose is defined in the Chapter Cooling Water. Following the setting up of
the cooling circuit, the latter must be inspected for its water-tightness.
NOTE
The plug connections of the cooling circuits may only be
connected or disconnected, at zero pressure.
The ingress of water into the devices (magnetron heads /
power supplies) as well as the condensation of the cooled
components in the devices must be prevented!
Only upon completion of the above steps can the electrical connection between the power
supplies and the magnetron heads be established!
The electrical connection must be established in accordance with the installation plan!
The connection cables must be in impeccable condition!
Pay attention to the Chapter "Security", as voltages of several thousand V occur in
microwave systems!
Finally the MW Power Supply is connected to the mains! In order to do so, the earth wire must
first be connected! Proceed according to the installation plan!
Prior to turning on the system, the individual points must be checked once more!
