2005-10-22 YYYY-MM-DD (see Settings menu for other date formats)
12:30:36 Current Time (24 hr HH:MM:SS format)
30kVA-3x3 30kVA = UPS rated output, 3 x 3 = 3-phase input and output
(Configuration)
Single, ECO, Master, Slave or Unit # 1
Single = single double-conversion unit
ECO = single stand-by unit with double-conversion fall-back
Master = master in a 1+1 Hot Stand By system
Slave = slave in a 1+1 Hot Stand By system
Unit # 1 = of max 6 double-conversion units in a parallel system
(Status)
Normal, Warning or Fault
