This cover plate is easy to open/remove in order to switch on or off a circuit breaker, or to connect additional loads. The cover plate can be opened or removed without the need of using special tools. The DC section of the Distribution Unit is made safe for a “User” to access, which follows the “Look and Feel” guidelines. 6.
74 Chapter 6 Routine Maintenance After one year of operation, all the units should be within the range of 13.50±0.48V. 6.5.3 Replacement 1) Replacing Criterion Replace the battery if its capacity measured during the battery test is less than 80% of the battery rated capacity. The capacity measured during the battery test shall be evaluated at a discharge rate close to its actual use. 2) Replacement Interval The battery is expendable, and has a certain life cycle.
Chapter 7 Troubleshooting Chapter 7 75 Troubleshooting 7.1 Troubleshooting Rectifier 1. Troubleshoot Rectifier according to LED Indication The usual fault symptoms of the rectifier include: power indicator (green) off, protection indicator (yellow) on, protection indicator (yellow) blinking, alarm indicator (red) on, and alarm indicator (red) blinking.
76 Chapter 7 Troubleshooting If the current sharing is still unsuccessful after the correction, replace the rectifier of which the current sharing function is disabled. 7.2 Mains Failure Mains failure often occurs in power system operation. Batteries will provide backup DC power in case of short-period of mains failure. If the cause of mains failure remains unknown or the failure lasts too long, the generator should be started to provide mains supply to the system.
