WARNING! •Refrigerating compressors are pressurised machines and thereforerequireparticularcautionandcareinhandling.

•Risk of burns! Depending on the operating conditions, surfacetemperatures of over 60 °C on the pressure side or below 0 °C on the suction side can be reached.

•Themaximumpermissible overpressuremustnotbe exceeded, even for testing purposes.

3| Areas of application

ATTENTION! Compressor operation is possible within the operating limits shown in the diagrams. Please note the significance of the shaded areas. Thresholds should not be selected as design or continuous operation points.

- Max. permissible discharge end temperature 140 °C -Max.permissibleswitchingfrequency12x/h. - A minimum running time of 3 min. steady-state condition

(continuous operation) must be achieved.

For operation with supplementary cooling: - Use only oils with high thermal stability. - Avoid continuous operation near the threshold. - Additional fans (accessories) or water-cooled cylinder covers (accessories) can be used for additional cooling.

For operation with capacity regulator: - The suction gas superheat temperature may need to be reduced

or set individually when operating near to the threshold. - The limits of application are reduced.

Foroperationwithfrequencyconverter: - The maximum current and power consumption must not be

exceeded. Inthecaseofoperationabovethemainsfrequency,the application limit can therefore be limited.

When operating in the vacuum range, there is a danger of airenteringonthesuctionside.Thiscancausechemicalreactions,a pressure rise in the condenser and an elevated compressed-gas temperature. Prevent the ingress of air at all costs!

SerienmotorAusführung für Direkt- oder TeilwicklungsstartVerdichter mit dieser Kennzeichnung ist für Direkt- oder Teilwicklungsstart (PW-Anlauf) geeignet.Der Motor ist in zwei Teilwicklungen unterteilt: Teil-wicklung 1=60% und Teilwicklung 2=40%. Dadurch wird beim Teilwicklungsstart der Anlaufstrom um ca. 35% gegenüber dem Direktstart verringert.

Für den Teilwicklungsstart (PW-Anlauf) ist die Verwendung einer mechanischen Anlaufentlastung mit Bypass-Magnetventil nicht erforderlich.Im Bedarfsfall kann der Anlaufstrom beim PW-Anlauf zusätzlich um bis zu 10% durchVerwendung einer mechanischen Anlaufentlastung (Zubehör) verringert werden.

Werkseitig ist der Motor für Direktstart geschaltet. Für den Teilwicklungsstart sind die Brücken zu entfernen und die Motorzuleitung gemäß Schaltschema anzuschließen:

WARNUNG! Nichtbeachten führt zu gegenläufi gen Drehfeldern und hat Motor-schaden zur Folge. Nach Anlauf des Motors über Teilwicklung 1 muß nach maximal einer Sekunde Verzögerungszeit Teilwicklung 2 dazugeschaltet werden. Nichtbeachten kann die Lebensdauer des Motors beeinträchtigen.

SondermotorAusführung für Direkt- oder Y/∆-AnlaufVerdichter mit dieser Kennzeichnung ist bei niederer Spannung für Stern-Dreieck-Anlauf geeignet.

Bei Y/∆-Anlauf ist eine Anlaufentlastung mit Bypass-Magnetventil erforderlich.

Werkseitig ist der Motor für den Direktstart bei höherer Spannung geschaltet. Für den Stern-Dreieck-Anlauf bei niederer Spannung sind die Brücken zu entfernen.

ATTENTION!

Terminals 1 - 6 on the trigger unit MP 10 and terminals PTC 1 and PTC 2 on the compres-sor 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 terminals11,12,14and43.

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 terminalboardconnectionboltsshorten; thiscanresult inwindingand terminalboarddamage.

INFO! In order to protect the compressor against inadmissible operating conditions,high-pressureandlow-pressurepressostats controls are mandatory on the installation side.

Thecompressorhasundergonetrialsinthefactoryandallfunctionshavebeentested.Therearethereforenospecialrunning-ininstructions.

Checkthecompressorfortransportdamage!

6.2 Pressure strength test

DANGER! 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.
