RFC-1 Installation page 3.2
3.2.1 Mechanical Installation
The RFC-1 and RP-8 should be mounted in a standard 19-inch equipment rack. The system generates little heat. It
can be mounted in nearly any convenient location. The RP-8 panels should be mounted at a location that is
convenient to the control and metering sources that will be connected to it.
A flat cable is supplied for interconnection between the RFC-1 and the RP-8. The factory supplied cable is three feet
long but it can be replaced with a longer one if the RFC-1 and RP-8 are to be mounted further apart.

3.2.2 RFC-1 / RP-8 Interconnect
The RFC-1 should be connected to the RP-8 relay panel(s) with the 16 conductor flat (ribbon) cable. This cable is
supplied with the RFC-1. The cable is terminated with one connector at each end. If more than one RP-8 is used in
a system, an extra connector will be supplied with the additional RP-8. The additional connector must be crimped
onto the existing flat cable assembly.
Adding an extra connector to the flat cable is easy—just be careful and be patient. First, slide the connector over the
end of the ribbon cable. Be sure to check three things:
• The colored stripe (usually red) is on same side of all connectors
• The ribbon cable lines up with the alignment slots in the connector
• The connector is perpendicular to the length of the cable
When you are sure that the connector is aligned properly, squeeze the connector together with a small vice or a pair
of pliers. A couple of small blocks of wood or cardboard will protect the plastic connector from the “gripping teeth” of
the vice or pliers. The latches on the edges of the connector will lock into place when the connector is squeezed
together sufficiently.
Plan your installation cable before you install additional connectors. For multiple RP-8 panels that are mounted next
to each other in the rack, the connectors should be placed about six inches apart on the cable. The supplied cable
should work for the most installations. Longer cables may be used if necessary.
