1 Normal operation, no deviation from specifications.
2 Normal operation, temporary deviation from specifications possible.
3 Will be replaced by EN 50155.
4 i = input, o = output, c = case
5 Only met with extended input voltage range of CK (48 V battery) and EK (110 V battery) types. These units are available upon cus-
tomer's request. Standard DK units (110 V battery) will not be damaged, but overvoltage lock-out will occur during the surge.
Under normal operation temporary deviation from specifications possible.
