3. GPE4890A System Configuration
GPE4890A consists of distribution unit, rectifier module (up to 3
sets) and 1 monitoring module. The configuration is optional, as
following table:
| Configuration | Rectifier Module | Monitoring Module | Power Distribution |
| Standard | GPR4830A1 | GPM48DI (With Ethernet Port) | GPE4890A: AC Input: 40A×1; DC Output: 40A×4 (load); Battery Output: 70A×1 (battery) |
4. GPE4890A Operating Principle
Under normal conditions, every parameter of rectifier modules and
distribution unit are all under control of the monitoring module,
operating according to the pre-set parameter or user’s commands. If
AC mains fault, the system will be powered by the battery. With the
battery discharge, the terminal voltage of the battery starts to
descend. When the battery voltage is under 42V±0.5V, the monitoring
module reports battery under voltage alarm signal and cuts off the
load output, then the power system stops working. When the external
AC mains recovers, the system will resume to the normal work state.
(All above monitoring data are system default values that users can
reset).

6.2 GPE4890A Installation
GPE4890A is embedded power system. First insert GPE4890A to the
specified location till the system is well fixed. Keep the 4 fixing
holes on the bracket in line with those on the cabinet and then
screw up 4 M4 cross rounded head screws, with the spring washer and
flat washer. At last finish the installation after tightening the
screw.
