RH-8: Installation Guide 3
3 Electrical Installation
Each RH-8 is fitted with an RJ45 data socket and supplied with a
3m patch cord. We suggest that a separate RJ45 floor socket is
located adjacent to every RH-8 control panel location and that the
supplied patch lead is used to link the RH-8 to the floor socket; this
approach simplifies maintenance. Each individual floor socket
should be wired ‘pin to pin’ directly to the equipment rack using
unscreened ‘Category 5’ cable (4 pair CAT 5). The total cable
length from an RH-8 to the rack should not exceed 100m (328ft).

The RJ45 plug is a compact 8-pole
connector primarily designed for CAT5
cable. The pin out for the RJ45 plug and
socket is shown to the right:
Special tools are available making termination both easy and quick. Instructions for termination
of an RJ45 plug are as follows:
1) Strip approximately 1” of outer sheath from the cable.
2) Remove extraneous material such as plastic wrap or foil screen from the 8 exposed cores
but do not strip their sheaths.
3) Cut the 8 exposed cores down so that when the cable is inserted into the RJ-45 the outer
core can be held by the plugs cable retention system.
4) Insert the 8 cores into the RJ-45 plug fully making sure that they are all correctly arranged.
(Information for the correct arrangement of cores for the RH-8 can be found on page 3&4)
5) Place the plug/cable assembly into the assembly tool and operate the mechanism.
6) You should now have a firmly connected plug/cable assembly that is ready for installation.
Note: The above instructions are for guidance only; always follow the instructions supplied with
the assembly tool.
When mounted directly on to a wall or perhaps the bulkhead of an exercise machine the RJ45
socket of the RH-8 may not be accessible. In this scenario it may be preferable to hard wire a
cable directly to the RH-8 using its internal screw terminals. When using the screw terminals
the use of a separate RJ45 floor socket adjacent to the RH-8 is still suggested.
Please note: The Pump Station 16 and Sub Station 8 have been discontinued as of March
2002 and November 2001 respectively, information regarding wiring an RH-8 to either of these
units can be found on pages 4 & 5.
