Select the cable cross section in accord-
ance with the instructions in

from page

Strip the insulation of the single conduct-
ors by 12 mm. Lift to open the terminal's
operating lever and insert the stripped
single conductor into the slot provided, in
each case as far as it will go. Then close
the operating lever until it engages.

NOTE!

No multi-wire connections are possible
with this terminal type.

Only one conductor may be connected to
each pin. The DC cables can be connec-
ted to the DC terminals without ferrules.
