Introduction Operation with Mains 1 down (figure 12) In the event of a Mains 1 failure or Mains 1 voltage outside specified tolerance of –10 % in amplitude (–15 % optionally), the rectifier-charger stops and the battery supplies the necessary backup power to the load via the inverter. The battery, float- connected between the rectifier-charger and the inverter, discharges during this operating mode. The green "load protected" light 5 on the control panel is on. The user is warned of battery o

Introduction Operation with Mains 1 restored (figure 13) When Mains 1 power is restored or its voltage returns to within specified tolerances, the system automatically returns to its normal operating mode described above (on the condition it did not reach the end of battery power). If the end of battery power was reached (with the resulting inverter shutdown), the RC restarts automatically, but the inverter must be restarted manually, either locally or remotely in systems equipped with a r

Introduction Installation with an engine generator set (figure 15) If a stand-by generator is included in the installation, it is generally started automatically in the event of a Mains failure and connected to the main low voltage switchboard. It is disconnected when Mains power is restored. With such a system, the required battery time may be reduced to the time necessary for starting and bringing on line the stand-by generator. The battery supplies power to the inverter during the tr

Introduction Frequency converters without redundancy – in the event of a shutdown, the load is no longer supplied with power; – in the event of a major transient overload (greater than 160 % of the rated load), the inverters will current limit to 160 % of their rated current for 1 second before stopping; – in the event of a small but extended overload (i.e. a continuous level of power exceeding the full rated load), the inverters will continue to supply power for a period depending on the ma

Control panel 3.1 Visible control panel Located in the upper left part of the cubicle front, the visible panel is designed to provide an easy and rapid overview of system status (see figures 22 and 23). Interpretation of symbols is very simple and requires no particular training. The information concerns only the cubicle on which the panel is located. The panel indicates: – normal operation (load protected); – abnormal situations (operating problem); – dangerous situations (load not protecte

It beeps at a low decibel level and slow rate for minor problems and when the load is supplied from battery power. When the "low battery shutdown imminent" warning is received, the beeps increase in decibel level and rate. Finally, if the inverter shuts down, the beep is loud and continuous.

In short, it signals that the system is operating normally. Note: In parallel systems, this light concerns only the specific UPS. The load may not be protected if it depends on the other lines. It is necessary to take into account all the "load protected" lights for the different system lines o
