Wiring and Piping
All pneumatic piping connections on the RP418 and RP818
are sized for 1/4-in. (6mm) OD polyethylene tubing. The con-
nections are sharp, barb-type connections. See Fig. 6 and 7.
Wiring connections on the RP418A and RP818A are made via
splices inside the splice box. Knockouts are provided on the
box. For ambient temperatures between 100 to 120°F (38 to
49°C) either use 75°C rated wire or attach a close-coupled
4 x 4 electrical box to the RP418A or RP818A splice box.
Make the wire splices within the electrical box.
Wire leads provide a means of connection on the RP418B
and RP818B. Use standard wire nut connectors, obtained
locally, when making these connections.
NOTE: A cord and plug are provided for wiring connections
on the RP418C.
The RP418 and RP818 relays require no adjustment or
calibration.
