VOCABULARY Primary circuit, HXL300-PS01 A closed circuit filled with coolant that connects the drive to the HX- unit. Secondary circuit, HXL300-PS02 A circuit filled with coolant that connects the HX-unit to the customer piping. HX-unit HXL300 cooling unit (see the front picture of the manual). The ordering code for the unit on the front page is HXL-M-300-N-S, but it is referred to as HXL300 or just plain HX-unit for short. Drive Liquid cooled frequency converters or inverters that are connected to the HX-unit. Main drive A term used in some contexts for the Vacon NX liquid Cooled converters so that they are more easily separated from the air- cooled Vacon NXP 0016 used in the HX-unit. The main drive concept might also include other liquid cooled electrical equipment. HX control unit The air-cooled NXP 0016 drive that is placed inside the HX-unit for the purpose of controlling and monitoring the primary circuit pump and instruments…. 1.2 GENERAL WARNINGS AND NOTES WHEN WORKING WITH THE HX-UNIT These safety instructions are intended for all who work on the HX-unit. These instructions include only a part of the complete safety instructions. Read the Vacon NX Liquid Cooled User’s Manual safety instructions as well. Ignoring the instructions can cause physical injury or death. It can also cause serious malfunctions to the HX-unit that is not covered by the warranty. When working on the HX-unit generally acknowledged safety standards, EU directives and national regulations must also be followed. 1 Only qualified and authorized electricians and mechanics are allowed to carry out the installation and maintenance work on the HX-unit. 2 Do not open the drive section doors while the drives are online. If you suspect a coolant leak in the drive section, shut down the drives and disconnect the power to them before opening the drive section cubicle doors. 3 When working with the HX-unit together with the frequency converter, also follow the Vacon NX Liquid Cooled Drive User’s Manual safety instructions to prevent any accidents. 4 Any installation work on the HX-unit must be done with power off. The power must not be reconnected before the installation work is complete. 5 The primary cooling circuit can contain hot coolant (over +50qC) during normal operation. Serious burns are possible. Before performing maintenance, switch off the unit and allow it to cool down. 6 The primary cooling circuit can contain high-pressure coolant (6 bar) during operation. Release the pressure in the HX-unit before performing maintenance. Use safety goggles. 7 The HX-unit must be positioned in a non-hazardous area where it can’t pose a threat to any main systems or persons. 8 The coolant consists, depending on the project, of plain drinking water or of a mix of water, propylene glycol and corrosion inhibitors. Glycol and corrosion inhibitors are dangerous to health. If you get coolant mixed with glycol or corrosion inhibitors in your eyes, on your skin, or in your mouth, seek medical advice. NOTE 1 It isthe customer’s and/or end-user’s responsibility to provide flow and temperature control to the secondary circuit. If the project specified flow and temperature for the secondary circuit is not met the warranty is not valid. 2 Retain theseoperating instructions during the entire life cycle of the HX-unit. 3 The HX-unit should always be transported empty (that is, without coolant) to prevent damage caused by low and high ambient temperatures. 4 Do not allow any force or vibrations to enter the unit through the secondary circuit pipe connections or through the fixing points of the HX-unit.
