Safety notes General safety notes for installation and operation • Ensure you are using the right capacitor type for your application. Please refer to the Siemens product installation manual and product manual for proper selection of capacitors. Please contact Siemens for any assistance required in selection. -
Page 8: Storage And Operation Conditions
Safety notes 2.2 Storage and operation conditions Storage and operation conditions Do not use or store capacitors in a corrosive atmosphere, especially where chloride gas, sulfide gas, acid, alkali, salt or similar substances are present. In a dusty environment, regular maintenance and cleaning, especially of the terminals, is required to avoid a conductive path between phases and/or phases and ground. -
Page 9: Ambient Temperature
Safety notes 2.3 Ambient temperature Ambient temperature The ambient temperature category for most standard types is–40 / D. This means a max. temperature of 55 °C, an average temperature over 24 hours of 45 °C, and the average temperature in one year should not exceed 35 °C. The maximum casing temperature of 60 °C must not be exceeded. - Page 10 Safety notes 2.3 Ambient temperature Note Only qualified personnel are permitted to install, commission or service this device. Wear the prescribed protective clothing. Observe the general equipment regulations and safety regulations for working with high-voltage installations (e.g. DIN VDE, NFPA 70E as well as national or international regulations).

Page 11: Mounting
Mounting Mounting the capacitors Figure 3-1 Capacitor overview Mounting positions Capacitors installed in a cabinet should be placed on the bottom to ensure the lowest stress temperature possible. WARNING The use of damaged devices may result in death, serious injury, or property damage. Do not install the capacitor in case of dents deeper than 0.5 mm. - Page 12 Mounting 3.1 Mounting the capacitors The PhaseCap Premium, PhaseCap Compact and PhaseCap Energy+ (Height of capacitor ≤ 224 mm) capacitor series may be mounted in the vertical or horizontal position. Note The pictures depicted above are for illustration purposes only. Actual sample will be as per MLFB type.

Page 13: Cooling Space For Capacitors
Mounting 3.2 Cooling space for capacitors Cooling space for capacitors Make sure that sufficient cooling space is provided: • A minimum distance of 20 mm between the capacitors is necessary to maintain sufficient cooling. • Keep at least 20 mm space above the capacitor and do not attach any mounting components at the crimp or on top. -

Mounting 3.3 Fixing threaded bottom stud Fixing threaded bottom stud The threaded mounting stud is at the bottom of the capacitor: Fixing The threaded bottom stud must be fastened with certain specified torques: • PhaseCap, PhaseCap Compact, PhaseCap Energy +, PhaseCap HD, DeltaCap: M12 bottom stud: torque 10 Nm. -
Page 15: Grounding
Mounting 3.4 Grounding Grounding The M12/M8 bottom stud is used for grounding. Connect it to the ground by cable, or connect the capacitor to any other conductive item which is connected to the ground. Note Connect the capacitor case to ground. Suitable connectors have to penetrate existing layers of lacquer to ensure good, constant conductivity and sufficient current carrying capabilities. -
Page 16: Connecting
Mounting 3.5 Connecting Connecting When connecting, avoid bending cable lugs or cables, or the use of other forms of mechanical force on the terminals. Otherwise, leakage could disable the safety device (overpressure disconnector). Provide sufficient mechanical strain relief for the cable. Ensure firm fixing of terminals, fixing torque to be applied as per individual specification. - Page 17 Mounting 3.5 Connecting Note Capacitor may be damaged. Do not exceed the maximum allowable current. Use an appropriate screw driver. Capacitors are supplied with partially engaged terminal screws. • PhaseCap Premium, DeltaCap, PhaseCap Compact, PhaseCap Energy+ except terminal type F and PhiCap: 5.5 x 1/Ph2/Pz2 type •...

Page 20: Inrush Current Limitation
Mounting 3.7 Inrush current limitation Inrush current limitation Switching LV PFC capacitors can cause high inrush currents of more than 200 times the rated current, especially when they are connected in parallel to others that are already energized. This may cause additional stress to contactors as well as to capacitors and reduce their life cycle. Inrush currents have a negative effect on power quality, e.g. -

Page 23: Harmonics
Harmonics Harmonics are voltages and currents with frequencies that are different from a 50 Hz or 60 Hz power supply frequency. Harmonics result from the operation of electrical loads with non-linear voltage-current characteristics. They are mainly caused by loads operated with modern electronic devices, such as converters, electrical drives, welding machines and uninterruptible power supplies (UPS). - Page 24 Harmonics Installation and maintenance instructions for Power Factor Correction (PFC) capacitors Installation Manual, 05/2022, L1V30884033A...

Page 25: Overpressure Disconnector
Overpressure disconnector Electrical components do not have unlimited life expectancies; this also applies to self-healing capacitors. As polypropylene-type capacitors seldom produce a pronounced short circuit, HRC fuses or circuit breakers alone do not offer sufficient protection. All capacitors of the PhaseCap Premium, PhaseCap Compact, PhaseCap Energy+, PhaseCap HD, DeltaCap and PhiCap series are consequently fitted with a disconnector that responds to overpressure. - Page 26 Overpressure disconnector Installation and maintenance instructions for Power Factor Correction (PFC) capacitors Installation Manual, 05/2022, L1V30884033A...
