Design Guide | iC7 Series Liquid-cooled System Modules Cooling Requirements Safety in Liquid-cooling WARNING POISONOUS COOLANTS Glycols and inhibitors are poisonous. If touched or consumed, they can cause injury. Prevent the coolant from getting into the eyes. Do not drink the coolant.
Page 38 Design Guide | iC7 Series Liquid-cooled System Modules There are two types of circulation system: open systems and closed systems. Always use a closed system with liquid-cooled drives. An open system has no pressure but the hydrostatic and pumping pressure. It allows free contact between the coolant and air. Air is continuously dissolved into the coolant, which corrodes and damages the components.

Page 60 Pump, cooling module Open the valves A (V212) and B (V213) of the cooling module. If you have a Danfoss cooling module, make sure that the valve V211 is open. The valve V211 is in series with V212. Start the filling pump P Wait for the system module M1 to fill up.
Page 61 Keep on filling until the specified liquid surface or system pressure is reached. If you have a Danfoss cooling module, keep on filling until the liquid surface reaches the default level marked in the indication pipe of the expansion vessel.
Page 62: Condensation
Air Cooling Requirements iC7 Series Liquid-cooled System Modules are liquid-cooled, but in a liquid-cooled drive system, there are always some heat losses to the air. The heat losses come from the busbars, fuses, and other auxiliary components. When installing the system modules and other components to an enclosure, ensure that there is sufficient airflow in each section.
Page 63 Design Guide | iC7 Series Liquid-cooled System Modules The door or bottom part of the enclosure must have air gaps for air intake, and outlet air gaps at the top. The inlet and outlet air gaps must obey the requirements set by the selected protection rating. The structure in the enclosure must move the hot air to the outlet at the top of the enclosure.

Page 73: Dc-Bus Connection Inductance
Design Guide | iC7 Series Liquid-cooled System Modules DC-bus Connection Inductance 7.10 Certain DC-bus connection inductance configurations can induce resonance between the DC capacitors of the drive and DC-bus inductances. The resonance can be seen as increased DC-bus RMS current (DC + AC) and component temperatures in the drives. The drive can typically compensate the resonances, but at a certain inductance range, the resonance frequency between the drives can fall into a range where the compensation may not be effective enough.

Page 113: Maintenance
Preventive Maintenance Recommendations Generally, all technical equipment, including Danfoss AC drives need a minimum level of preventive maintenance. To ensure trouble-free operation and long life of the drive, regular maintenance is recommended. It is also recommended as a good service practice to record a maintenance log with counter values, date, and time describing the maintenance and service actions.
Page 114 Design Guide | iC7 Series Liquid-cooled System Modules Table 42: Maintenance Schedule for Liquid-cooled Drives (continued) Component Inspection Service Preventive maintenance actions interval schedule Corrosive environ- 1 year – Conductive dust and aggressive gases, such as sulphide, chloride, and salt mist, can ments damage the electrical and mechanical components.
Page 115 The advantage of using a pre-mixed coolant hibitor is that the chemical composition is within Danfoss specifications, and there is no need for analyzing the coolant. Demineralized 1 year Based on Only use demineralized or deionized water in the coolant solution.
Page 116: Maintenance Log For Cooling System
Imbalanced temperature of the cooling circuits is a possible sign of a re- striction. Under normal conditions, clean or acid-wash the heat sinks every 6 years with Danfoss recommended cleaning products. Refill the coolant system and log the new coolant specification values.
