Capacitors integrated in servo amplifiers may be uncharged to absolute zero level, if servo amplifiers are stored for longer than a year without being connected to mains voltage. If rated voltage is supplied to such a capacitor, then an extremely high charging current (depending on the charge characteristics curve) may flow for some time, which could overheat and destroy the capacitor or the PCB. Even load cycles during this phase  result in high current peaks due to recharging processes.
