1 Hints on the manual This handbook contains instructions for the installation and operation of door or side-mounted, bolt-on Cooling Units provided by Pfannenberg. In this manual, safety recommendations and other information are structured as follows. If the measures described in the following are not strictly observed there is danger to life and health.
(Also refer to warranty 17 Any damage must be reported immediately to the forwarding agent Moreover, the latest edition of the "Pfannenberg After Sales Service Declaration" shall apply. •Before disposing of packing material ensure that it does not contain any loose components.
For the installation and maintenance, please take note of the technical data on the name plate which can be found on the back of the cooling unit. 6 Safety Cooling units produced by Pfannenberg are designed for use in dissipating heat from switch cabinets (IP 55). The cooling unit is only suitable for installing on the stationary operation.
7.3 Condensate During cooling, the moisture romoved from the hot air by the evaporator is collected as condensate. In order to avoid any damage to the switch cabinet and the cooling unit, the condensate must be discharged. The condensate is discharged in the following way: In case of normal condensate drainage a reservoir (option) collects the condensate which is then drained by means of a hose.

9 Installations 9.1 General •For effective cooling & ventilation, correct installation & ventilation of the cooling unit is very important. •The distance must be kept at least 500mm between units or the unit to the wall. •The cooling unit’s electrical connection terminal requires at least 40mm space and the electrical components shall not impede air circulation in the internal cabinet.
9.2 Installation work The mounting surface of the switch cabinet is to be provided with cutout(s) and holes for air ventilation openings and for securing the unit according to the accompanying sheet.According to the the section 9. The drawing on the accompanying sheet also shows the location of the electrical connections and ventilation openings.
9.3 Electrical connection • The cooling unit must be connected to the mains by means of a disconnecting device with a contact gap of at least 3mm when switch off. • No temperature regulator allowed to be series-connected to the cooling unit up-stream feed. •...
Communication Connection: The unit supports standard Modbus protocol and RTU mode. The factory default communication address: "1", Bau: "9.6Kbps". RS485 allows 32 units to be connected together as a network. In order to link cooling units, following methods shall be taken: •...
• The cooling unit is provided with power-on self-test and real-time monitoring function. The cooling unit will generate an alarm when there is a failture during power-on self-test. The cooling unit mustn’t be switched on without the front cover mounted otherwise it will be damaged by poor heat dissipation.
11.5 Equipment fault • Power fault signal 54—1 2pin is NC it closes when power supply is on properly failed power supply at the cooling unit will open the failure contact and the alarm code will be shown on the display. (See Section 16 for trouble shooting).
