Connection to a cooling unit￭ Connection to an ACS880-1007LC cooling unitRefer to ACS880-1007LC cooling unit user’s manual (3AXD50000129607 [English]).￭ Connection to a custom cooling unitGeneral requirementsEquip the system with an expansion tank to damp pressure rise due to volume changeswhen the temperature varies. Equip the system with a pump that provides a nominal flowand pressure. Keep the pressure within the limits specified in Technical data (page 70).Install a pressure regulator to make sure that the maximum permissible operating pressureis not exceeded.Install a bleed valve at the highest point of the cooling circuit, and a drain valve at the lowestpoint.The materials that can be used are listed in Cooling circuit materials (page 72).Coolant temperature controlThe temperature of the coolant in the internal cooling circuit must be kept within the limitsspecified in Technical data (page 70). Note that the minimum temperature is dependent onambient temperature and relative humidity.Internal cooling circuit 67
