Introduction to E5-PA series inverter for Multi-Pumps control
Matching V&T constant pressure water supply expansion card according to the demand. Setting H.00 when choosing different expansion card. Expansion card model and pictures as follows:
◆ The water supply control card must be installed in completely power off, and install it on the VFD expansion slot.
◆ Please confirm the setting value is the same as the installed expansion card when setting the function code. If not, it may cause the disorder of terminal initialization, affect the use.

Multifunctional M key
The unique multifunctional key is used to set the frequently used operations: JOG, emergency shutdown, running command reference mode switch , menu switching
Multiple menu modes
Basic menu mode, fast menu mode. Menu mode of non-leave-factory value function codes, Menu mode of last changed 10 function codes
The standard operation panel can realize the parameter upload, download and display the copy progress. The user can select to forbid the overwriting of the uploaded parameters.
The customer can select to display or hide the function codes by themselves.
485 communication ports support Modbus protocol (RTU). The standard operation panel can realize remote control box function with a maximum distance of 500m.
Button type or shuttle type operation panel optional, protection class: IP20 as standard, IP54 as option
Common DC bus
The full series can realize common DC bus supply for several inverters.
The full series adopts independent duct design and supports the installation of heatsink outside the cabinet
