- Strip the end of the wire aproximately 1/4"
- push down the orange wedges using a small screw-
driver
- insert the stripped wire
- remove the screwdriver to complete the connection
- To remove, push down the orange wedges and pull
out the wire!
Connection Example Using One Master and Three Basic Drives:
8.4.3.2 Addressing
When using the cascade serial/synchron mode in a multi-pump-application (where
more than drive is used), each drive must be addressed correctly.
Master drive – The address of the Master drive is set using the Hydrovar software.
Dip switches are used to program the Basic drives to a specific address. On all Master
drives the dip switches must be set to address 1 (default setting, see below).
Basic Drive – When using a Basic drive in a Multi-pump-system the dip switches must
be set to the appropriate address for each drive in the system. The addresses for the
Basic drives start after the last address of the final Master drive in the system. The
S1 switchbank is located on the lower board behind the control panel. (See pictures
below for locations.)
Example:
Multi-pump-system with 3 Master and 4 Basic drives
• Set address 1-3 for the Master Inverters via appropriate software parameters (See
submenu CONF INVERTER [0100] or submenu RS485-INTERFACE [1200])
• Address 4-7 for the Basic Inverters via dip-switches
The pre-selected address also defines the initial pump sequence.
