Supplementary devices

Installation:

1. Mounting one S2C-S/H6R

→ RCCB or MCB must be in the ON position → remove coupling cover on the right side of the MCB/RCCB → signal contact/auxiliary

switch in ON position

→ if fitted to MCB, remove bottom (RCD), if fitted to RCCB middle (MCB) coupling pin → plug devices together.

2. Mounting more than one S2C-S/H6R

Up to three S2C-H6R can be mounted.

Note: one signal contact max. fitted at first to MCB or RCCB

If fitted to an MCB, remove the bottom coupling pin (RCD), if fitted to an RCCB, remove the middle coupling pin (MCB), switch all signal

contact/ auxiliary switches to the end position ON, plug them together and carry through a function control test.

Function control test:

After all signal contacts/auxiliary switches or auxiliary switches have been mounted, use the upper coupling pin to switch on the devices

(ON position). If the lower (for RCD) or, as the case may be, the middle (for MCB) coupling pin is operated, all devices must trip.

Now combination with MCB/RCCB:

RCCB or MCB must be in the ON position

→ remove coupling cover on the right side of the MCB/RCCB → signal contact/auxiliary switch

in ON position

→ if fitted to MCB, remove bottom (RCD), if fitted to RCCB middle (MCB) coupling pin → plug devices together.
