Assembly 2.1 Mounting the valve terminal Warning Uncontrolled movements of the connected actuators and uncontrolled movements of loose tubing can cause injury to persons and/or damage to property. • Make sure that the higher-order controller has not sent control signals to the solenoid coils. • Before carrying out conversion work on the CDVI, switch off the following: – The compressed air supply – The power supply Note Handle all the components of the CDVI with great care. Note especially the following: – Avoid an offset between the components, otherwise the protection class requirements may no longer be fulfilled (see Appendix A, “Technical data”). – Components must be screwed without offset and mechanical stress. Screws must be fitted accurately (otherwise threads may be damaged) – Observe the specified tightening torques. – Make sure that the connecting surfaces are clean (avoid leakage and contact faults). – Avoid operating the CDVI in the resonant range. 2-4 Festo P.BE-CDVI-EN en 1202e 2. Assembly 2.1.1 Wall mounting It may be sensible to connect the tubing prior to mounting the CDVI, depending on the space available for mounting. The tubing of the terminal is described in chapter 3. Caution The CDVI can bend and therefore become damaged and may leak if it is mounted on an uneven and pliable surface. • Mount the CDVI only on an even rigid surface. Procedure: 1. Ascertain the weight of your terminal (weigh or calculate). Guidelines: Components of the CDVI Weight Basic weight: 1) – CDVI with 4 valve positions – CDVI with 8 valve positions CDVI-MP approx. 1050 g approx. 2090 g Expansion block with 1 valve position 2) – With/without additional supply approx. 255 g Expansion block with 2 valve positions: 2) – With/without additional supply approx. 510 g Valve approx. 210 g/item Blanking plate approx. 85 g/item Multi-pin connecting cable per metre approx. 168 g/m Spacer bolt approx. 80 g/item CDVI-FB approx. 1320 g approx. 2360 g --- 1) Manifold block, without: separator plates, left-hand and right-hand end plates, pneum. threaded connectors, cable, valve 2) Expansion block without: separator plate and pneum. threaded connectors, valves Tab. 2/1: Weight specifications for the CDVI Festo P.BE-CDVI-EN en 1202e 2-5 2. Assembly 2. Make sure that your mounting surface can support this weight and that it is sufficiently earthed. Note Attaching the CDVI manifold block: – The 8-valve manifold block must always be fastened to all 4 M6 drill holes. Attaching the CDVI with expansion blocks: – 1 valve position may protrude unfastened. – If the expansion provides more than one valve position, fasten the last expansion block. However, please note that a maximum of 4 valve positions may lie unsupported between the manifold block and last expansion block, i.e. you need to fit an intermediate retainer after 4 valve positions at the latest. 3. Drill corresponding mounting holes ∅ 6 mm into the mounting surface. 1 1 1 Mounting holes Fig. 2/1: Position of the mounting holes 2-6 Festo P.BE-CDVI-EN en 1202e 2. Assembly 4. Fasten the terminal conductively with the earthed mounting surface (see Fig. 2/2). If necessary use washers. The terminal can be mounted in any desired position, but the CDVI should be mounted so that dirt will be washed out during cleaning and the cleaning agent can drip off. 1 2 3 1 Earthed mounting surface 2 Spacer bolt, tightening torque 10 Nm 3 Manifold block with threaded holes for spacer bolts (±2 Nm) Fig. 2/2: Example of vertical attachment Festo P.BE-CDVI-EN en 1202e 2-7 2.

Installation Contents of this chapter Further information This chapter deals with the tubing and cabling of the CDVI. These include in particular the following: – General instructions on preparing the compressed air and on connecting the tubing – Instructions on operating the pilot control with internal or external pilot air supply – Instructions on operating the valve terminal with pressure-zone separation – Fitting the QS threaded connectors – Connecting the power supply – Earthing the CDVI – Address assignment of the valves Instructions on connecting the electric components of the CDVI with MP connection can be found in the brief description “CDVI with multi-pin plug connection.” Instructions on connecting the electric components and on addressing the CDVI with DI connection “DeviceNet” can be found in the electronics manual P.BE-CDVI-DN-.. Festo P.BE-CDVI-EN en 1202e 3-3 3. Installation 3.1 Compressed air preparation Note Unfiltered or incorrectly lubricated compressed air will reduce the service life of the valve terminal. 3.1.1 Operation with unlubricated compressed air Note Too much residual oil content in the compressed air will reduce the service life of the valve terminal. – If bio oils are used (oils based on synthetic esters or native esters, e.g. rapeseed oil methylic ester), the residual oil content must not exceed max. 0.1 mg/m3 (see ISO 8573-1 class 2). – If mineral oils are used (e.g. HLP oils to DIN 51524 Part 1 to 3) or corresponding oils based on polyalphaolefin (PAO), the residual oil content must not exceed 5 mg/m3 (see ISO 8573-1 class 4). This avoids operative malfunction of the valves. Excessive residual oil is not permissible irrespective of the compressor oil, as otherwise the basic lubrication will be washed out with time. 3-4 Festo P.BE-CDVI-EN en 1202e 3. Installation 3.1.2 Operation with lubricated compressed air Operate your system with unlubricated compressed air if possible. This will prevent pollution of the environment. Festo pneumatic valves and actuators have been designed so that, if used as intended, they will not require additional lubrication and will still achieve a long service life. Caution Operation with lubricated compressed air will cause the life-time lubrication, which is necessary for unlubricated operation, to be “washed out”. Note the following instructions if lubricated compressed air must be used. The compressed air prepared with the compressor must correspond in quality to unlubricated compressed air. If possible, do not operate the complete system with lubricated compressed air. If possible, always install the lubricators directly in front of the consuming actuator. Caution Incorrect additional oil and too much residual oil content in the compressed air will reduce the service life of the valve terminal. – Use Festo special oil OFSW-32 or the other oils listed in the Festo catalogue (conforming to DIN 51524-HLP32, basic viscosity 32 CST at 40 °C). – The additional lubrication must not exceed 25 mg/m3 (ISO 8573-1 class 5). – Check that the lubricator setting is correct (see subsequent section) This avoids operative malfunction of the valves. Festo P.BE-CDVI-EN en 1202e 3-5 3. Installation Setting the lubricator: with the machine running (typical operating status) 0.2 to max. 1 drop/min. or 0.5 to 5 drops/1000 l air. Checking the setting: the procedure described below can be used for checking the setting of the lubricator. Procedure: • Check the service units for condensate and lubricator setting twice per week. 1. Ascertain the actuator which is furthest from the lubricator. 2. Ascertain the valve terminal which controls this cylinder. 3. Remove the silencer, if fitted, from port (3/5). 4. Hold a piece of white cardboard 10 cm in front of the exhaust port. 5. Let the system run for a short period. – There must be only a slight yellow colouring on the cardboard. If oil drips out, this is an indication that too much oil has been used. Another indicator of over-lubrication is the coloration or the condition of the exhaust air silencer. A distinctly yellow colouring of the filter element or drops of oil on the silencer indicate that the lubricator setting is too high. 3-6 Festo P.BE-CDVI-EN en 1202e 3. Installation 3.2 General instructions on installation Warning Sudden unexpected movements of the connected actuators and uncontrolled movements of loose tubing lines can cause injury to human beings or damage to property. Before carrying out mounting, installation and maintenance work, switch off the following: – Compressed air supply – Operating and load voltage supplies. Pay attention to the following: The components of the valve terminal contain electrostatically sensitive elements. The components will be damaged if you touch the contact surfaces of the plug connectors or if you do not observe the handling specifications electrostatically sensitive components. Festo P.BE-CDVI-EN en 1202e 3-7 3. Installation 3.3 Laying the tubing If elbow connectors or multiple distributors are used, the airflow will be reduced slightly. Connecting Proceed as follows: 1. Push the tubing as far as possible into or over the tube coupling of the threaded connector. 2. Tighten the clamping screw 1 or, if applicable, pull the locking ring 2 over the tube coupling. 3. Seal connections that are not required with blanking plugs 3. 4. For better system clarity, bundle together the installed tubes with: – tubing straps or – multi-tube holder 1 2 3 Fig. 3/1: Fitting the tubing 3-8 Festo P.BE-CDVI-EN en 1202e 3. Installation Disconnecting Proceed as follows: Warning Pneumatic tubing that is under pressure can execute uncontrolled movements when being dismantled, causing injury to persons. Carry out the following steps before disconnecting the pneumatic tubing on the CDVI valve terminal: • Switch off the compressed air supply. • Make sure that all pneumatic tubing is pressureless. • Exhaust all actuators controlled by valves which are closed in normal or mid-positions. 1. Mark all pneumatic tubing. 2. Loosen the clamping screw 1 of the fitting or, if applicable, press down the locking ring of the fitting 2 e.g. with a Festo QSO releasing tool. 3. Remove the tubing from the threaded connector. 1 2 Fig. 3/2: Disconnecting the tubing Festo P.BE-CDVI-EN en 1202e 3-9 3. Installation 3.4 3.4.1 Notes on installing the CDVI Pilot control of the solenoid coils (pilot air supply) Note – Operate the CDVI whenever possible with unlubricated pilot air (port (12/14)). Otherwise observe the instructions in the section “Compressed air preparation”. – In the case of CDVI with internally branched pilot air, the above-mentioned instruction applies also to the supply air (port (1)). The pilot air is supplied centrally to all valves of the CDVI. – Therefore, operate the valve terminal either with internally branched or externally supplied pilot air. This will ensure reliable operation of the valve terminal. Internal pilot air supply If the operating pressure of the CDVI is between 3 ... 8 bar, you can operate the pilot control of the solenoid coils with an internally branched pilot air supply. Note • Internal pilot air supply is branched centrally from supply port (1) in the right end plate for all solenoid coils. This also applies when the CDVI is operated with several pressure zones (see Fig. 3/3 and Fig. 3/4). 3-10 Festo P.BE-CDVI-EN en 1202e 3. Installation If the CDVI is intended for internal pilot air supply, port (12/14) on the left-hand end plate must be sealed with a blanking plug. External pilot air supply If the operating pressure of the CDVI lies below 3 bar or above 6 bar, pilot control of the solenoid coils must be operated with an external pilot air supply. Note • Use regulated external pilot air (3...8 bar). Then reliable, trouble-free operation of the CDVI is possible, e.g. even with fluctuating operating pressure. • The external pilot air supply is supplied centrally for all solenoid coils via the pilot port (12/14) on the left end plate. This also applies when the CDVI is operated with different pressure zones (see Fig. 3/3 and Fig. 3/4). • Set the pilot pressure of the external pilot air supply to correspond to the operating pressure with which these valves are operated (see Appendix A, Fig. A/1). 3.4.2 CDVI with pressure zone separation The CDVI can be equipped with 2 to 9 pressure zones. There is not intended to be a pressure zone separation within the manifold block. The CDVI must be fitted with at least one expansion block in order that two pressure zones can be created. Festo P.BE-CDVI-EN en 1202e 3-11 3. Installation Note With more than 2 pressure zones: Ensure that there is a corresponding pneumatic supply port for each pressure zone. Conversion of the CDVI to 2 to 9 pressure zones is described in chapter 5 “Cleaning, maintenance and conversion.” Note All the valves of the CDVI are supplied with pilot air from a central source. The pilot air is either branched internally from channel (1) or supplied externally via port (12/14). This also applies if the CDVI has several pressure zones. With internal pilot air supply and pressure zone separation of channel (1), observe the following: – The internal pilot air supply is branched in the right end plate from channel (1). The operating pressure in the right zone must therefore lie between 3...8 bar. In the left and centre pressure zones the operating pressure may lie between -0.9...10 bar and 3...10 bar, depending on the valves that are used (see Appendix A “Technical data”). Separator plates For the CDVI the following separator plates are available for creating pressure zones: Function Separator plate type Channel (1) blocked CDVI5.0-EB-DZP Channel (3/5) blocked CDVI5.0-EB-DZR Channels (1) and (3/5) blocked CDVI5.0-EB-DZPR Tab. 3/1: Separator plates with channel separation 3-12 Festo P.BE-CDVI-EN en 1202e 3.

Tab. 3/4: Separator plate combinations for creating pressure zones 3.4.3 Operating the CDVI with vacuum/low pressure Note The valves with ident. code H, K and N (2x3/2-way valves) are not permitted for operation with vacuum/low pressure. A pneumatic spring takes over resetting these valves to the normal position. This spring is operated with the operating pressure (channel (1)). An operating pressure of at least 3 bar is required for resetting the valve. • Operate these valves in a separate pressure zone. • The operating pressure for this pressure zone must be set in accordance with the diagram in appendix A, Fig. A/1 . Thefollowing requirements must be fulfilled so that you can operate the CDVI at the supply port (1) with vacuum or low pressure between -0.9...3 bar: 3-16 Festo P.BE-CDVI-EN en 1202e 3. Installation – The pilot control of the solenoid coils is operated with a regulated external pilot air supply. – The valve terminal is fitted with the following valve subbases and, in some cases has two pressure zones. Valve sub-bases Pressure zone with vacuum or low pressure supply The pressure zone must be equipped only with the following valve sub-bases: – 5/2-way valve, monostable (ident. code M) – 5/2-way valve, double solenoid (Ident. code J) – 5/3-way valve (ident. code B, E and G) – 3/2-way valve (Ident. code W and X) (see also subsequent note). – 2/2-way valve (ident. code R and S) The valve sub-bases with Ident. code N, K and H, if supplied via port (1), are not suitable for vacuum/low pressure! Pressure zone with excess pressure supply 1) via port (1) The pressure zone can additionally be equipped with the following valve sub-bases: – 2x3/2-way valves (Ident. code H, K and N) 1) In accordance with diagrams in Appendix A, Fig. A/1 Tab. 3/5: Valve sub-bases Note 3/2-way valves with ident. code W and X: 2/2-way valves with ident. code R and S: – These valves can be supplied individually and therefore operated in the pressure range of -0.9 … 10 bar. They are independent of supply port 1 of the valve terminal. The ports via which these valves are supplied with compressed air or vacuum and via which exhaust air is removed are shown in Appendix A, Tab. A/6, or Tab. A/7. The above mentioned valves are supplied with pilot air via port 12/14 of the valve terminal. Festo P.BE-CDVI-EN en 1202e 3-17 3.

For optimum efficiency of your terminal, the compressed air supply and the exhausting should take place in the following cases via the left and right-hand end plates: 3-18 – On valve terminals with more than 10 valves (nominal supply pressure 6 bar) – On large capacity actuators: Festo P.BE-CDVI-EN en 1202e 3. Installation Caution Larger actuators or actuators operated simultaneously (e.g. cylinders) can create a back pressure in the exhaust duct of the valve terminal. The size of this back pressure depends on the capacity of the ducted exhaust tubing. This may lead to malfunctioning of the CDVI. • In this case, exhaust the CDVI via ports (3/5) on both end plates and, if necessary, on the expansion block. • In order to avoid interactions with adjacent valves, valves on expansion blocks can be separated by means of a separate exhaust duct (3/5). Note Under certain circumstances, excess pressure can build up under the valve covers of the CDVI. This pressure is reduced via the pressure compensation hole in the manifold block. • Do not on any account plug the hole for the pressure compensation. • Remove the excess pressure with ducted tubing. Do not use any non-return valve in the line. Note Some ports have been covered with adhesive transparency as protection against contamination. • Remove all adhesive transparencies from the ports. • Seal the following if not used: – unused valve positions with blanking plates – working ports (2), (4) with blanking plugs or plugs for QSF plug connectors.

Installation 3.5.2 Connecting the electric cables Warning • Use for the electrical power supply only PELVcircuits in accordance with IEC/DIN EN 60204-1 (Protective ExtraLow Voltage, PELV). Also comply with the general requirements for PELV circuits in accordance with IEC/DIN EN 60204-1. • Use only powersources that guarantee reliable electrical isolation of the operating voltage according to IEC/DIN EN 60204-1. By the use of PELV circuits, protection against electric shock (protection against direct and indirect contact) is guaranteed in accordance with IEC/DIN EN 60204-1 (electrical equipment of machines, general requirements). Note Check within the framework of your EMERGENCY STOP circuit, to ascertain the measures necessary for putting your machine/system into a safe state in the event of an EMERGENCY STOP (e.g. switching offthe operating voltage for the valves and output modules, switching off the compressed air). Note Due to energy stored in the input circuitry of valve terminals, there may be a delayed reaction of the valves when the load voltage is switched off. Take this into consideration, e.g. as follows: – Detect that the load voltage has been switched off by means of an input signal in the controller. – Block the control signal for the valves by locking the output signal with the input signal “Load voltage”. 3-22 Festo P.BE-CDVI-EN en 1202e 3. Installation Detailed instructions on installing the electrical connections of the CDVI-MP can be found in the leaflet type P.BE-K-CDVI supplied with the product. Detailed instructions on wiring the electrical connections of the CDVI with DI connection “DeviceNet” can be found in the electronics manual P.BE-CDVI-DN-... Earthing the CDVI Note Interference from electromagnetic sources. • Earth your CDVI. Make sure that there is a conductive connection (low impedance, short cable with large cross section) between the CDVI and the earth potential. 3.6 Address assignment of the valves Detailed instructions on addressing CDVI with DI connection “DeviceNet” can be found in the electronics manual P.BE-CDVI-DN-... The CDVI occupies 16 or 24 addresses, depending on the number of valve positions, irrespective of the types of valves fitted. This enables the CDVI valve terminal to be extended at a later date without the need to shift the addresses.

Commissioning Contents of this chapter Further information Festo P.BE-CDVI-EN en 1202e This chapter deals with the commissioning of the CDVI. This includes in particular the following: – Instructions on building up pressure in the overall supply – Checking the valves and the valve-actuator combination – The function of the manual overrides – Troubleshooting – Assignment of the LEDs Instructions on diagnosing and troubleshooting on the CDVI with DI connection “DeviceNet” can be found in the Electronics Manual P.BE-CDVI-DN-... 4-3 4. Commissioning 4.1 4.1.1 4.1.2 Instructions on commissioning Before commissioning • Switch off the power supply before connecting or disconnecting plugs (otherwise this could lead to functional damage). • Commission only a valve terminal which has been fitted and wired completely. • Make sure that there is a sufficient supply of fresh air (cooling) for the following operating conditions: – When the maximum number of valves are fitted – When the maximum operating voltage is applied – When the solenoid coil is constantly under stress • Please observe the following instructions on building up pressure in the overall supply. Pressure increase in the overall supply Warning If the pressure build-up of the pilot air supply is too slow or delayed, this may cause the actuators to perform sudden unexpected movements under the following conditions: – When the compressed air is connected via a soft-start valve (gradual pressure build-up) and – When there are electric signals (e.g. after EMERGENCY STOP). This can cause damage to the machine or system and even injury to persons. • Operate the valve terminal with an external pilot air sup- ply (3 ... 8 bar). Branch the pilot air supply before the soft-start valve (see Fig. 4/1). 4-4 Festo P.BE-CDVI-EN en 1202e 4. Commissioning The pilot air must be applied with a pressure of 3 ... 8 bar immediately after being switched on, otherwise there is no guarantee that the valve will reverse directly (see diagram). If the pressure is less than 3 bar, there may be a delay before the valve reverses, in spite of an electric signal. The gradual pressure build-up of the overall supply does not affect the actuator in that case. The actuator would react suddenly (e.g. a cylinder would extend or retract suddenly, depending on the valve function). 82/84 4 2 14 12 1 12/14 5 3 2 3 1 2 12/14 1 1 Externally supplied pilot air (3 ... 8 bar), branched before the soft-start valve 2 Soft-start valve (gradual pressure build-up of the overall supply) Fig. 4/1: Example of valve-cylinder combination with gradual pressure build-up of the overall supply Festo P.BE-CDVI-EN en 1202e 4-5 4. Commissioning The table below shows the effects of slow start-up pressurisation when there are electric signals: External pilot air Pressure rise in Pressure rise supply overall supply in the pilot air supply (12/14) Time when a valve reverses Movement of the actuator branched after the soft-start valve slow slow after pressure rise at (1) fast branched in front of the soft-start valve slow fast before pressure rise at (1) slow Tab. 4/1: Effects of slow start-up pressurisation 4.2 4.2.1 Checking the valves and the valve-actuator combination Manual override You should use the manual override especially when commissioning the pneumatic system, in order to check the function and operation of the valve or the valve-actuator combination. By actuating the manual override, you can switch the valve without an electric signal. You only need to switch on the compressed air supply. The manual override has been designed to be used as follows: Manual override design Mode of operation Manual override with automatic return (pushing) The manual override is reset automatically by spring force. Tab. 4/2: Actuation types of the manual override 4-6 Festo P.BE-CDVI-EN en 1202e 4. Commissioning The assignment of the manual overrides to the solenoid coils is as follows: 1 MO for solenoid coil 14 2 MO for solenoid coil 12 2 1 Fig. 4/2: Position of the manual overrides 4.2.2 Checking Note Before commissioning the CDVI, note the specifications on the medium, see chapter “Installation,” section “Pilot air supply.” Proceed as follows when commissioning the valve terminal: Festo P.BE-CDVI-EN en 1202e 4-7 4. Commissioning Commissioning variant Activity Preliminary test of the pneumatic tubing Checking the valve-actuator combination by means of the manual override (MO) Complete commissioning of the entire system Installing and connecting the entire system. Program control via PLC/ industrial PC. Tab. 4/3: Commissioning variants Commissioning by means of the manual override is described below. Warning Before actuating the MO: Uncontrolled actuation of solenoid coils can cause the actuators to perform sudden unexpected movements which may cause personal injury and material damage. • Disconnect the operating voltage supply for the solenoid coils from the relevant connections on the valve terminal. • Actuate the MOs only with a blunt object This avoids unintentional actuation of the valve solenoid coils and damage to the MOs. Before switching on the power supply: During commissioning, manual override functions which are in the switched state can cause actuators to perform sudden unexpected movements. These movements can cause injury to persons and damage to property. • Make sure that all manual override actuations are reset to their basic positions. You will thereby avoid undefined switching states of the valves. 4-8 Festo P.BE-CDVI-EN en 1202e 4. Commissioning Procedure: Warning Before testing the valve-actuator combination: – Make sure that nobody is in the danger zone. Note A valve which has been switched by an electric signal (in switch position), cannot be reset to the normal position by actuation of the manual override. The electric signal is dominant in this case. • Reset the electric signal before actuating the manual override. 1. Switch on the compressed air supply. 2. Check the functioning and effect of each valve-actuator combination by actuating the relevant manual override. 3. Make sure that all valves are in the normal position before commissioning the valve terminal. 4. Switch off the compressed air supply after testing the valves. Festo P.BE-CDVI-EN en 1202e 4-9 4. Commissioning 4.3 LED displays of the valves There is a yellow LED for every solenoid coil. This LED shows the switching status of the solenoid coil.

Cleaning, maintenance and conversion 5.1 Cleaning the CDVI The CDVI from Festo is a valve terminal especially for the splash range in the food and packing industry. It features in particular the following: – Increased resistance to corrosion – Resistance to acid and alkaline cleaning agents – Compliance with relevant protection classes (see Appendix A “Technical data”). – Easy to clean. Caution Disinfectants may contain substances which can damage the components of the CDVI in the long or short term (e.g. sodium hypochlorite). – Avoid using cleaning agents with a sodium hypochlorite basis. – Do not disinfect the CDVI with ultra-violet light. – Note that the IP protection class refers to cold water without cleaning agents. Cleaning agents can reduce the surface tension. In individual cases you should consult the manufacturer of the cleaning agent/disinfectant regarding its compatibility with the CDVI. 5-4 Festo P.BE-CDVI-EN en 1202e 5. Cleaning, maintenance and conversion Clean the valve terminal as follows: – Use aluminium-compatible cleaning agents (e.g. from Henkel Ecolab, Diversy Lever or Kärcher) Use the cleaning agent in the concentration, at the processing temperature and in an environmentally friendly manner according to the specifications of the manufacturer (see data sheet), but not at a processing temperature over +50°C. • Festo P.BE-CDVI-EN en 1202e After cleaning rinse the CDVI with plenty of clear water, so that the cleaning agent cannot dry. Otherwise there will be “increased concentration” which may damage the surface of the CDVI. 5-5 5. Cleaning, maintenance and conversion 5.2 General preventive action Warning Uncontrolled movements of the connected actuators and uncontrolled movements of loose tubing can cause injury to persons and/or damage to property. • Make sure that the higher-order controller has not sent control signals to the solenoid coils. • Before carrying out conversion work on the CDVI, switch off the following: – The compressed air supply – The power supply The CDVI is supplied pre-assembled from the factory. If you wish to supplement or replace individual components, please note the following: 5-6 Festo P.BE-CDVI-EN en 1202e 5. Cleaning, maintenance and conversion Note Handle all the components of the CDVI with great care. Note especially the following when mounting components: • Screws must be fitted accurately (otherwise threads will be damaged). • Screws must be fastened only by hand. Screws must be fitted so that the self-cutting threads can be used. • The specified torques must be observed. • Threaded connections must be mounted free of offset and mechanical tension. • Avoid an offset between the components, otherwise the protection class requirements may no longer be fulfilled (see Appendix A, “Technical data”). • Check the seals for damage before fitting (IP 65). • Make sure that the connecting surfaces are clean (avoid leakage and contact errors). • In the case of components ordered at a later date, observe also the fitting instructions supplied. Caution Components may be damaged if they are not handled correctly. • Observe the handling specifications for electrostatically sensitive devices. • Discharge yourself of static electricity before fitting or removing the components in order to protect the modules against static discharges. • Do not touch the contact surfaces of the plug connectors on the sides of the components.
