Page 4: Introduction
Do not attempt to work on a powered APCQ capacitor bank. After switching off the power supply to the APCQ capacitor bank, always wait at least 5 minutes before working on the unit (i.e. time for the power capacitors to be discharged). Always verify by measurement that capacitors are dis- charged. -
Page 5: Upon Reception
Figure As an option, APCQ-M and APCQ-R can also be delivered in wood crates / sea worthy packing as per Figure 4. Immediately after reception, please inspect the delivery and make sure that the packing is in good conditions. Report immediately to your HITACHI ENERGY representative any damages. -
Page 6: Identification Tag
Figure 2: Lifting lugs 3.2. Identification tag The APCQ capacitor bank nameplate is located on the front door, at the outside. A second similar nameplate is pre- sent inside the cubicle.

Page 19: Power Cables Selection
To disconnect the unit from the network, HITACHI ENERGY suggests preferably a circuit breaker. A 3-phase discon- necting fuse or a 3-phase switch with fuses may nevertheless be used. The circuit breaker should be chosen with a nominal current rating of minimum 1.5 times the rating of the APCQ ca- pacitor bank. -
