How to connect

 

This product must be connected to a controller.

 

 Up to 15 controllers (1 master unit and 14 slave units) can be connected to this 

product.

 

Always turn OFF the power before connecting or disconnecting a controller to/

from this product. Connecting a controller to this product with the power turned 

ON may damage the product and controller.

Insert the male connector all the way into the female connector. If the connector 

is not connected completely, the product and controller may become damaged.

 

To connect this product to a controller, always mount them on a DIN rail. To do 

so, mount end plates 

MS-DIN-E

 (optional) or commercially available fittings so 

as to enclose the connected units at both ends.

 

For notes on using controllers, refer to the instruction manual provided with the 

controller.

 

When the 

HG-S

 controller and 

HG-T

 controller are used in combination, note the 

following points.

•  Connect the slave units of the same series to the side closer to the master 

unit, and connect the slave units of the different series to the far side.

•  Some functions such as computation function and copy function are restricted. 

For detailed information, refer to the user’s manual of each controller(

our 

Website: https://panasonic.net/id/pidsx/global

 ).

•  If the 

HG-T

 controller is connected with 

HG-S

 controller manufactured prior to 

January 2019, it will not operate properly. Be sure to connect the product to 

HG-S

 controller manufactured in or after February 2019.
