Page 41: Standby Mode
Operation Standby Mode The RD Series features an automatic transfer relay and an internal battery charger when operating in Standby Mode. Standby Mode begins whenever AC power (utility power or generator) is connected to the inverter’s AC input. Once the AC voltage and frequency of the incoming AC power is within the AC input limits, an automatic AC transfer relay is activated. -

24.2 VDC on 24-volt models) or lower, the unit will begin another bulk charge. * These settings in the RD Series are changeable and leave the factory with default values (see Table 3-2, Inverter/Charger Default Values). These default values are adequate for most installations, however, if you determine that some of the values need to be changed for your particular system, the ME-RC50 remote control may be purchased to adjust these settings. -
Page 43: Transfer Time
The transfer from Standby Mode to Inverter Mode occurs in approximately 16 milliseconds. While the RD Series is not designed as a computer UPS system, this transfer time is usually fast enough to hold them up. However, the VAC dropout setting has an effect on the ability of the loads to transfer without resetting. -
