1.3 Safety instructions
WARNING!
• Refrigerating compressors are pressurised machines and
therefore require particular caution and care in handling.
• Risk of burns! Depending on the operating conditions, surface
temperatures of over 60 °C on the pressure side or below 0 °C on
the suction side can be reached.
• The maximum permissible overpressure must not be exceeded,
even for testing purposes.
• The compressor may be operated only if it is free of defects!
• No work may be performed when an explosive atmosphere is
present!
• Smoking, fire and open flame are strictly prohibited! Mobile telephones must be switched off!
• Strongly charge-generating processes must be excluded within
2 meters. The contact of rapidly moving particles with the surface of the compressor must be avoided with certainty (e.g.
pneumatically moved dust, flowing fluids, direct ventilation, belt
drives, brushes, foils, etc.).
• Perform installation work only if no damage, leaks and/or
appearances of corrosion can be recognized.
D
GB
The Bock refrigerating compressors named in the title are intended for installation in machines that
were set up in areas falling under the EU Explosion Protection Directive 2014/34/EU. In the European
Union, electrical as well as mechanical devices operated in explosive atmospheres must fulfil what
are known as ATEX (ATmospheres EXplosibles) conditions.
The compressors are specially designed for the category shown on the name plate in accordance with
the ATEX directive and may only be used in conformity with the conditions specified and documented
in the set-up area (explosion protection document). User safety is taken into account as a particular
focus of design. But it is permissible to start up the compressor only if it was installed in accordance
with these instructions and the entire system into which it is integrated has been inspected in accordance with legal regulations and approved.
The declarations and remarks by Bock can only refer to the product itself. We assume that the applicable regulations, standards and technical rules are followed in installation and during operation. The
plant constructor/operator must evaluate the interactions with other devices and components of the
system and with the environment, especially regarding potential ignition sources.

2.2 Ignition protection concept
In accordance with Directive 2014/34/EU, Bock ATEX compressors are suitable for use in device
category 2 for explosive gas atmospheres up to temperature class T3 and explosion hazard subgroup IIB/IIC.
For the compressor, essential characteristics of the protection type pressurization (Ex p) are applied.
Fundamental part of this protection type is the exclusion of oxygen by using an inert gas, in this case
refrigerant. By means of static pressurization (Ex p) the motor is completely surrounded by refrigerant
and is thereby protected from explosive atmosphere. For protection against the loss of this static
pressurization, safety pressure switches must be installed on the low pressure side of the compressor
according to EN 60079-2 to shut-down the compressor before reaching the atmospheric pressure.
To prevent ignition risk caused by working materials also during system malfunctions, all used
working materials have to meet the requirements for the temperature class of the compressor.
The surface temperature of the compressor may not exceed 80% of the ignition temperature of the
working material. For this reason all working materials need to have an auto-ignition temperature of
> 250°C.
D
GB
F
E
I
To protect against high temperatures that may occur during incorrect operation or faults at the
compressor, the areas with the highest heat potential are controlled with temperature sensors (Ex b).
The installation of the electronic control unit MP10 and the safety barrier, both included in the scope
of supply, is therefore absolutely necessary.
The connection areas for load circuits are designed according to the requirements of the appliance
category in Ex e. The circuits for the temperature sensors of the used ignition source control Ex b have
to be intrinsically safe to prevent inadmissibly high thermal or electric values. To ensure the intrinsic
safety, the included safety barrier has to additionally be integrated in the electric circuit according
to this assembly instruction. The terminal board is designed as an interface between Ex e and Ex p
chamber in Ex d respectively Ex de. The whole electric connection area is protected by a housing that
complies with the requirements for the protection type increased safety (Ex e).
Accessories
Heating elements for the compressors to protect against explosion risks are designed in the protection
types increased safety (Ex e) for the make Thuba and pressure-proof housing (Ex d) for the make
Elmess and have to have to be mounted stationary at the designated areas in the compressor housing.
The heating elements can be operated without temperature- and oil level control since the thermal
type testing by the manufacturer verified that the heating elements prevent the exceeding of the
temperature class of the compressor. The electric connection of the heating elements has to be done
in a protective housing that complies with the requirements of an approved protection type. The
control has to be carried out in a way that the heating element can only be operated during shutdown
of the compressor.
The magnetic coil of the capacity regulator is designed in the protection type encapsulation (Ex m) to
protect against explsion risks. In addition, the connecting areas of the coil are placed in a housing that
complies with the requirements of the protection type increased safety (Ex e).

2 | Product description
The oil pressure differential sensor INT250 from Kriwan is executed as a simple electrical operating
device without a recognised ignition protection type. To ensure reliable operation, however, it must
be equipped as an intrinsically safe electrical circuit with safety barriers. Please note that the plastic
housing of the INT250 can be electrically charged by means of charge-generating processes (e.g.
cleaning with a dry cloth, direct additional ventilation via fan etc.). Accordingly, the operator is required
to take measures so that ignition hazards can be reliably ruled out.

3.2 Important information on the use of hydrocarbons
Hydrocarbons (combustible refrigerants) may be used in the compressors named in the title only if all
relevant and applicable regulations, standards and technical rules are followed. National safety regulations must be observed. In addition, we refer to the following applicable standards and regulations:
EN 378, BGR500, TRBS 2152, EC Directives 1999/92/EC and 2014/34/EU.
The compressor and the refrigeration system must be permanently equipped with clear, identical
labels/plates (ISO3864) that state that combustible refrigerants are used. This warning plate must be
unremovably attached to the compressor.
A hazard analysis in accordance with the Operational Safety Ordinance must be performed for the
set-up location. Use and handling of the refrigeration system and compressor are to be governed in
the explosion protection document.
D
GB
F
E
I
Installation, placement into operation, service and repair (as permitted by the manufacturer) may only
be performed by personnel who have been specially trained on combustible refrigerants.
If the compressor has to be removed from the system for inspection/maintenance/repair, the remaining
refrigerant must be suctioned out and the compressor evacuated, filled with nitrogen (<0.5 bar) and
closed gas-tight. The compressor must be equipped with a tag that clearly states that the compressor
was operated with combustible refrigerant (name the refrigerant).
If the system contains combustible refrigerants or residues, extreme caution must be exercised when
working on the compressor due to the danger of explosion. This applies especially for the use of
fire, open flame or other ignition sources (e.g. electronic devices, mobile telephones, static charges,
sparks, ...).
During maintenance and repair, it must be noted that hydrocarbon residues may remain dissolved in
the oil. In addition used dryers contain bottoms of the inflammable refrigerants. Flush the dryer with
nitrogen and supply it to the recycling.
It should be noted that the solubility of hydrocarbons in oil can be very high, especially at high suction
pressures. A high-viscosity lubricant may be required, depending on the application and experience.
The lubricant must be released for use by Bock. Depending on the application, a pump-down switch
should also be added (e.g. when the refrigeration system is set up outside).

3.4 Limits of application
For operation with capacity regulator:
- Continuous operation, when the capacity regulator is activated,
is not permissible and can cause damage to the compressor.
- The suction gas superheat temperature may need to be reduced
or set individually when operating near to the threshold.
- When the capacity regulator is activated, the gas velocity in
the system can not under certain circumstances ensure that
sufficient oil is transported back to the compressor.
For operation with frequency converter:
- the maximum current and power consumption may not
be exceeded. During operation above the mains frequency
the application limit can be restricted.
Variable frequency range: 25-70 Hz
During operation in the vacuum range, there is a danger of air
entering on the suction side. This can cause chemical reactions, pressure rise in the condenser and an excessive pressure
gas temperature as well as shifting of the refrigerant ignition
limit into the critical range. Avoid absolutely any entry of air!
Two safety pressure switches on the low pressure side
according to EN 60079-2 have to be provided.
The shut-off point has to be set at least 50 Pa higher than the
prevailing ambient pressure! Safety devices detecting over
pressures have to be installed and designed according to
EX-directives and must comply with the requirements of the
EN 60079-2!

INFO!
• New compressors are factory-filled with inert gas (3 bar nitrogen).
Leave this service charge in the compressor for as long as possible and prevent the ingress of air.
• Check the compressor for transport damage before starting any
work.
• Before starting work, obtain written work release.
• Observe national regulations when setting up explosion-protected
systems (within the EU: ATEX Directive 1999/92/EG, EN 60079-14,
EN 60079-17 a.o.).
• Use only tools permitted for explosion-protected systems (within
the EU, in accordance with EN 1127-1).
• Observe work safety rules (TRBS 2153, e.g. protective shoes,
clothing etc.)!
4.1 Pressurization of the compressor
D
GB
F
The operation of the compressor below the atmospheric pressure is not permissible. To prevent the
loss of this static pressurization e.g. because of leakages at seals, according to EN 60079-2 the
compressor has to be equipped with two automatically working safety pressure switches at the not
lockable connections of the low pressure side. The minimum over pressure with regard to the atmospheric pressure that is set at the safety pressure switches has to be at least 50 Pa.
E
4.2 Ignition source control of the compressor
I
To protect against an exceeding of temperature the protection type ignition source control "b" is
used at the compressor. Via sensors, the areas with the highest heat potential at every cylinder
cover are controlled. Additionally, the temperature of the motor winding is controlled by the safety
device MP10.
The permissible limit temperatures for normal operation of the compressor were set with 130°C for
the motor and with 140°C for the hot gas side of the cylinder cover. If one of those values is exceeded, the compressor is shut down by the control device MP10. Besides the installation according
to wiring diagram, the operator/installer does not have to regard other parameters for the correct
functioning of the ignition protection system. A function check however has to be carried out before
every startup of the compressor according to section 5.8 of this assembly instruction.
For a safe function of the ignition source control the MP10 has to be installed according to the
wiring diagram fig. 29, the restart interlock (bridge B2) must not be removed in any case. Check
the function of the ignition protection system according to section 5.9. Defective sensors or ignition
protection systems have to be replaced before reconnection of the compressor.
Operation of the compressor without igintion source control is not permitted!
After shutdown by the MP10, precise error diagnostics and error correction is necessary.

4.5 Pipe connections
The pressure and suction shut-off valves have graduated inside
diameters so that pipes in the common millimeter and inch dimensions
can be used. The pipe will be inserted more or less deep, depending on
the dimension.
The connection diameters of the shut-off valves are designed for maximum
compressor performance. The actual required pipe cross section must
be matched to the output. The same applies for non-return valves.
Fig.18: graduated
internal diameter
ATTENTION!
An explosive atmosphere must not be present!
Do not solder as long as the compressor is under pressure.
Superheating can damage the valve. Remove the pipe supports
therefore from the valve for soldering and accordingly cool the
valve body during and after soldering.
Only solder using inert gas to inhibit oxidation products (scale).
4.6 Pipes
D
GB
F
E
I
Pipes and system components must be clean and dry inside and free of scale, swarf and layers of
rust and phosphate. Only use air-tight parts.
Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being
cracked and broken by severe vibrations.
Ensure a proper oil return.
Keep pressure losses to an absolute minimum.
4.7 Laying suction and pressure lines
INFO!
Proper layout of the suction and pressure lines directly after the
compressor is integral to the smooth running and vibration behaviour
of the system.
ATTENTION! Improperly installed pipes can cause cracks and tears which can
result in a loss of refrigerant,
A rule of thumb:
Always lay the first pipe section starting from the shut-off valve downwards and
parallel to the drive shaft.

For systems with long pipes and higher degree of contamination, a filter on the suction-side is
recommended. The filter has to be be renewed depending on the degree of contamination (reduced
pressure loss).

DANGER!
High voltage! Risk of electric shock! Only carry out work when the
electrical system is disconnected from the power supply!
ATTENTION! When attaching accessories with an electrical cable, a minimum
bending radius of 3 x the cable diameter must be maintained for
laying the cable.

Connect the compressor motor according to the circuit diagram
(see Fig. 25-29 or inside the terminal box). Comply with local safety
regulations for electrical work, safety standards (within the EU:
EN 60204, EN 60335 among others) and regulations for setting up
electrical systems in explosion-endangered areas (within the EU:
EN 60079-14 among others).
Avoid damage to cable fittings, since otherwise operational safety
can be impaired. Lay the cable so that the fitting to the terminal box
will not loosen itself. If necessary (e.g. installation that is not twist
free), protection against loosening can be achieved through check
nuts or appropriate adhesive. Avoid abrasion points on cables.
For cable lead-through at the terminal box, use suitable Ex cable
screw connections in the correct protective version (see name plate).
Use strain relief. Avoid abrasion points on cables.
Install all switching devices outside the explosion-endangered area.
Motor contactors, feed lines and fuses are to be rated according to
the maximum operating current (see name plate). Recommendations
for contactor and motor protection selection are included in the table
at the end of the „Electrical system“ chapter 5.2.
Do not separate contacts 1 + 2 of the motor thermistors under voltage.
Compare the details for voltage and frequency on the nameplate with
the details for the electricity mains supply. The motor may only be
connected if these details match.
Use a motor protector switch. It should be set to the motor measurement current and checked.
For the installation of phases L1, L2 and L3 to line-up terminals U1, V1
and W1, no solid wire may be used.
cross section for connection of line-up terminals L1, L2 and L3 =
6 - 35 mm².
cross section for connection of line-up terminals 1, 2, 3 and 4 =
max. 2,5 mm².

5.1 Potential equalization
Before start-up, the potential equalisation must be connected (see Fig. 24).
INFO!
Special attention must be paid to sufficient conductivity of all
contact points. There must be a large seat (e.g. with ring cable lug).
The installed voltage equalization must be secured against loosing
and firmly connected to earth.
Potential equalization connection
Fig. 24
5.2 Information for contactor and motor contactor selection
WARNING! Always install all electrical peripheral devices in an external control
cabinet outside the explosion-endangered area!
All protection devices and switching or monitoring units must be fitted in accordance with the local
safety regulations and established specifications (e.g. VDE) as well as with the manufacturer’s information. Motor protection switches are required! Motor contactors, feed lines, fuses and motor
protection switches must be rated on the basis of the maximum working current (see name plate).
For motor protection use a current-dependent and time-delayed overload protection device for monitoring all three phases. Set the overload protection device so that it must be actuated within 2 hours,
if there is 1.2 times the max. working current.
5.3 Terminal cross section for leads
To limit the heating of conducting parts, the minimum terminal cross sections, indicated in the table
have to be followed.

Compressors marked in this way are suitable for direct or part winding start. The motor winding is
divided into two parts: part winding 1 = 66% and part winding 2 = 33%. This winding division reduces the start-up current during a part winding start to approx. 65% of the value for a direct start.
Mechanical start unloader with bypass solenoid is not required.
In the factory, the motor is connected for direct starting (YY). For part winding start (Y/YY) remove the
bridges and connect the motor feed cable according to the circuit diagram.

Failure to comply results in reversed fields of rotation and can cause
motor damage. After the motor has started up with part winding
1, part winding 2 must be switched on after max. 1 second delay.
Failure to comply can be detrimental to the service life of the
motor.

ATTENTION! Terminal boxes and cable screw connections must be properly
closed. Protective class IP 65 must be ensured. Ex cable screw fittings must be used (pay attention to correct assignment of the cable
and fitting diameter).
Icing/condensate formation in the terminal box of the compressor
must be avoided due to the danger of short circuits (e.g. through
appropriate suction gas overheating). Carefully set suction gas
overheating temperature! Check regularly for icing!

5.8 Electronic release unit MP10
ATTENTION! Install MP10 outside the explosion-endangered area
The MP10 trip unit must be installed according to the wiring
diagram (Fig. 28/29).
D
GB
F
E
I
The accompanying MP10 release unit must be installed corrosion-free in the external
switch cabinet outside the explosion-endangered area. Wire the release unit as the
first member in the control power circuit and protect it with a fuse that is rated no
larger than the smallest maximum permissible current of the installed component.
The MP10 does not have an ATEX identification.
When installing control and regulating parts, the respectively valid national
regulations for Ex protection must be observed!
When using the 24 V DC control voltage version of the Motor Protection Unit MP10, a
protection class 3 (SELV or PELV) safety transformer must be installed in series. The
safety transformer must conform to EN 60950-1
Pay attention to safety rules during service or repair work! Consider applicable laws,
standards, directives and possible new regulations before placing back into operation.
Use only new original parts when replacing old ones (e.g. cable screw connections)
Operate the electrical system only in an undamaged and clean condition; have it checked and serviced at regular intervals by trained personnel.
Carefully make conductor connections so that individual wires are not damaged. Properly prepare conductor ends of multiple-wire or fine-wire cables. Crimp wire end sockets only with suitable compression tools to achieve uniform quality. Ensure a secure
connection of all terminal locations! Check installation before start-up.
Connection and testing PTC-sensor
Wire the PTC temperature sensor of the compressor motor, heat protection thermostats of the cylinder head, pressure and temperature monitoring of the system
according to the wiring diagram (see Fig.27-29). In connecting the PTC sensor, pay
attention to:
- motor winding at terminals 1 and 2
- hot gas side at terminals 3 and 4
Terminals 1 - 6 on the trigger unit MP10 and terminals PTC 1 and PTC 2 on
the compressor terminal board must not come into contact with mains
voltage. This would destroy the trigger unit and PTC sensors.
The supply voltage at L1-N (+/- for DC 24 V version) must be identical to the
voltage at terminals 11, 12, 14 and 43.
Connections between terminals in the terminal box to which heat protection thermostats (terminals 3 + 4) are connected and the electronic release unit MP10 must be
designed as intrinsically safe sensor circuits and clearly marked in accordance with
EN 60079-14. Appropriate measures (e.g. barrier) must be taken.
Make the connecting lines intrinsically safe. Do not exceed the maximum resistance
of 50 Ω! Take into account the resistance values of the heat protection thermostats:
- Motor sensor as triple PTC resistor: 50 - 450 Ω (R cold at + 25 °C) not intrinsically safe.
- Hot gas sensor:Cold resistance ≤100 Ω (Rcold at + 25 °C per heat protection thermostat)
The sensor outputs of the MP10 itself are not intrinsically safe. A barrier including

6 | Commissioning
ATTENTION! All of the following work must be performed only by qualified personnel (see p. 4) and with exclusion of an explosive atmosphere.
6.1 Preparations for start-up
INFO!
In order to protect the compressor against inadmissible operating
conditions, high-pressure and low-pressure pressostats controls are
mandatory on the installation side.
The compressor has undergone trials in the factory and all functions have been tested. There are
therefore no special running-in instructions.
Check the compressor for transport damage!
6.2 Pressure strength test
The compressor has been tested in the factory for pressure integrity. If however the entire system is
to be subjected to a pressure integrity test, this should be carried out in accordance with EN 378-2
or a corresponding safety standard without the inclusion of the compressor.
D
GB
6.3 Leak test
DANGER!
F
E
I
Risk of bursting!
The compressor must only be pressurised using nitrogen (N2).
Never pressurise with oxygen or other gases!
The maximum permissible overpressure of the compressor must not
be exceeded at any time during the testing process (see name plate
data)! Do not mix any refrigerant with the nitrogen as this could
cause the ignition limit to shift into the critical range.
Carry out the leak test on the refrigerating plant in accordance with EN 378-2 or a corresponding
safety standard, while always observing the maximum permissible overpressure for the compressor.
6.4 Evacuation
ATTENTION! Do not start the compressor if it is under vacuum. Do not apply
any voltage - even for test purposes (must only be operated with
refrigerant).
Under vacuum, the spark-over and creepage current distances of the
terminal board connection bolts shorten; this can result in winding and
terminal board damage.
First evacuate the system and then include the compressor in the evacuation process.
Relieve the compressor pressure.
Open the suction and pressure line shut-off valves.
Evacuate the suction and discharge pressure sides using the vacuum pump.
At the end of the evacuation process, the vacuum should be < 1.5 mbar when the pump is switched off.
Repeat this process as often as is required.

6.5 Refrigerant charge
CAUTION!
Wear personal protective clothing such as goggles and protective
gloves!
Make sure that the suction and pressure line shut-off valves are open.
With the compressor switched off, add the liquid refrigerant directly to the condenser or receiver,
breaking the vacuum.
If the refrigerant needs topping up after starting the compressor, it can be topped up in vapour
form on the suction side, or, taking suitable precautions, also in liquid form at the inlet to the
evaporator.
INFO!
Avoid overfilling the system with refrigerant!
In order to prevent shifts in concentration, zeotropic refrigerant
blends (e.g. R407C) must always only be added to the refrigerating
system in liquid form.
Do not pour liquid refrigerant through the suction line shut-off valve on the compressor.
It is not permissible to mix additives with the oil and refrigerant.
D
6.6 Start-up
GB
WARNING! Ensure that both shut-off valves are open before starting the
compressor!
F
E
Check that the safety and protection devices (pressure switch, motor protection, electrical contact protection measures, etc.) are functioning properly.
Switch on the compressor and let it run for at least 10 minutes.
Check the oil level : The oil must be visible in the sight glass.
ATTENTION! If larger quantities of oil have to be topped up, there is a risk of oil
impact effects. If this is the case, check the oil return!
6.7 Avoiding liquid sluggings
ATTENTION! Slugging can result in damage to the compressor and cause
refrigerant to leak.
To prevent slugging:
The complete refrigeration plant must be properly designed.
All components must be compatibly rated with each other with regard to output (particularly the
evaporator and expansion valves).
Suction gas superheating at the compressor input should be min. 7 - 10 K (check the setting of
the expansion valve).
The system must reach a state of equilibrium.
Particularly in critical systems (e.g. several evaporator points), measures such as the use of liquid
traps, solenoid valve in the liquid line, etc. are recommended.
There should be no movement of refrigerant whatsoever while the compressor is at a
standstill.
