Close Mounting
When mounting the units closely in a horizontal row on
30mm centers, use optional barriers to prevent interconnec-
tion between adjoining terminals. The barriers can be
attached simply by pressing them onto the sides of contact
blocks.
When mounting transformer type illuminated units closely in
a horizontal row on 30mm centers, insert solid wires or
stranded wires into inside of the terminal screw on the trans-
former (see figure below) to prevent short circuit between
adjoining terminals.
When using transformer type pilot lights closely mounted in
horizontal and vertical rows on 30mm centers, keep the
ambient temperature below 40°C.
