1 Notes on documentation EN 1 Notes on documentation 1.1 CE labelling Rittal GmbH & Co. KG confirms the conformity of the cooling unit with the European Union's Machinery Directive 2006/42/EC and EMC Directive 2004/108/EC. A corresponding declaration of conformity has been issued and enclosed with the unit. 1.2 Storing the documents The assembly and operating instructions as well as all other applicable documents are an integral part of the product.
2 Safety notes 2 Safety notes Where applicable, use suitable components to divert General safety instructions Please observe the prescribed minimum distances at EN the air. 2.1 Please observe the following general safety instructions for the installation and operation of the system: – Please be sure to observe the applicable regulations governing electrical installations of the country in which the device is installed and operated as well as national regulations for accident prevention.
3 Product description EN 3 Product description 3.1 Functional description and components 3.1.1 Function There are two separate cooling circuits installed in the cooling unit. – One conventional refrigerant circuit (compression system), and – One heat pipe integrated into the condenser and evaporator coil.

Operation using this controller is described in section 7 "Operation". 3.1.
3 Product description EN 3.1.7 Door limit switch The cooling unit may be operated with a floating door limit switch connected. The door limit switch is available as accessory from Rittal. The door limit switch function causes the fans and the compressor in the cooling unit to gradually slow down and then switch off after approximately 15 seconds when the enclosure door is opened (contacts 1 and 2 closed). This prevents the formation of condensate water inside the enclosure while the enclosure door is open.
4 Transport and handling 4 Transport and handling 4.1 Delivery EN The cooling unit is supplied in one packaging unit. Check the packaging carefully for signs of damage. Traces of oil on damaged packaging indicate a loss of refrigerant and/or a leak in the cooling unit. Any packaging damage may be the cause of a subsequent functional failure. Fig. 3: 4.2 Unpacking Remove the packaging materials from the cooling unit.
5 Installation EN 5 Installation 5.1 Safety instructions Warning! Please note the maximum weights that may be lifted by individuals. It may be necessary to use lifting gear. Warning! Work on electrical systems or equipment may only be carried out by an electrician or by trained personnel under the guidance and supervision of an electrician. All work must be carried out in accordance with electrical engineering regulations.
5 Installation Under no circumstances should the air inlet and outlet EN openings of the cooling unit be obstructed. Only in this way is it possible to ensure that the maximum cooling output is available. Please ensure that the cold airflow from the cooling unit is not directed at active components. Fig. 6: Mounting options Key 1 External mounting 2 Partial internal mounting 3 Full internal mounting Fig.
5 Installation EN 5.3.3 Make a mounting cut-out in the enclosure In order to mount the cooling unit on the enclosure, a suitable mounting cut-out must be made in the door or side panel of the enclosure. In principle, the mounting cut-out is identical for all three mounting options. A special mounting cut-out is only required for external mounting on the side panel of a 500 mm deep enclosure. Note: The dimensions of the mounting cut-outs can be found in section 12.1 "Representation of mounting cut-outs".
5 Installation Lift up the cooling unit, preferably from a lifting eye us- EN ing suitable lifting gear, and initially set the cooling unit down with the two bottom threaded bolts on the door or side panel of the enclosure. If transportation by crane is not possible, lift the cooling unit into the mounting cut-out in the same way using the handle. Fig. 11: Corner brackets on the threaded bolts Key 1 Corner bracket 2 Threaded bolt Fig.
5 Installation EN These fastening clamps ensure that the cooling unit is directly in contact with the mounting cut-out of the enclosure door over the entire height. If applicable, re-attach the door or side panel including cooling unit to the enclosure, if not mounted directly on the enclosure. 5.3.5 5.3.6 Partial internal mounting of the cooling unit At the front of the cooling unit, pull the top louvred grille away from the mounting clips on the cover, and place or lay it down somewhere safe.
5 Installation EN Fig. 17: Remove the infill panel Key 1 Mounting clips 2 Cover 3 Infill panel On the rear of the display, disconnect both of the con- nectors (PE conductor and connection) and remove the infill panel completely from the cooling unit. Fig. 15: Key 1 2 3 4 Attachments on hinge mechanism Cover Stays in hinge mechanism Bracket Bottom louvred grille Pull the bottom louvred grille forwards out of its hold- ers, and place or lay it down somewhere safe. Fig.
5 Installation Caution! The cooling unit will only be stable as long as the cover and chassis are connected. For this reason, be sure to brace the chassis, in particular, to prevent it from falling over before removing the cover. EN Loosen the four threaded bolts in the corners of the cover which connect the cover to the chassis. Carefully pull the cover forwards (approx. 5 cm) from the chassis.
5 Installation Slide the flat-pin connector of the PE conductor into place, and ensure that the cover and chassis are connected. Warning! The PE conductor which connects the cover and the chassis must be connected to both connectors in all cases. Otherwise, there is a risk of injury from electric shock if the unit connection was faulty or defective. Place the cover fully over the chassis, and connect the cover and the chassis using the four threaded bolts in the corners of the cover. Fig.
5 Installation EN 5.3.7 Full internal mounting of the cooling unit First, dismantle the top and bottom louvred grilles as well as the infill panel and the display in the same way as for partial internal mounting (see section 5.3.6 "Partial internal mounting of the cooling unit"). Cut the sealing tape in the dispatch bag to the required length so that it can be placed all the way round the cover once.
5 Installation EN Fig. 30: Corner brackets on top threaded bolts Key 1 Threaded bolt 2 Corner bracket Mount the L-shaped brackets onto the bottom two threaded bolts from the outside. Fig. 32: Key 1 2 3 4 Mounting points on cooling unit Threaded bolts with nuts (4x) Fastening clamps Cooling unit behind enclosure door Front of cooling unit (without louvred grille) Insert the six fastening clamps into the cover of the Fig.
5 Installation EN – The hose must be laid with an adequate and constant gradient to prevent siphoning. – The hose must be laid without any kinks. – If extended, the cross-section of the hose must not be reduced. – The hose should be routed to a drain or external condensate water evaporator by the customer. Fig.
5 Installation EN Fig. 36: Key 1 2 3 4 Potential equalisation arrangement Ring terminal with PE conductor Contact washer Washer Screw Note: According to the standard, the PE conductor in the mains connection cable is not classed as an equipotential bonding conductor. Fig. 34: Key 1 2 3 4 Connections at rear 5.4.
5 Installation Micro-USB interface A micro-USB interface is located on the front, to the right of the display. A tablet or laptop may be connected here for easy configuration of the unit. Connect a tablet or laptop with installed RiDiag software to the micro-USB interface. No other USB devices will be detected on this connection. EN Fig. 38: Circuit diagram SK 3188940 and SK 3189940 There is also a cover for the connection box included in the dispatch bag.
6 Commissioning 6 Commissioning EN Note: The oil must collect in the compressor in order to ensure adequate lubrication and cooling. For this reason, do not operate the cooling unit for at least 30 minutes after assembling the equipment. Observe the aforementioned waiting period of at least 30 minutes before commissioning the unit after assembly. Next, switch on the voltage supply to the cooling unit.
