Terminal covers (RXZ40.1) are available as an option, to protect the connection termi-
nals from physical contact and dirt. These covers also provide strain relief for the cable
connecting the extension module to the RXC30 / RXC31 / RXC38 controller.
The terminal covers must be used on equipment mounted outside the control
panel or distributor box. When fitting the terminal covers, make sure that they
snap into position correctly.
