Electrical Wiring to I nterface Link
Lite Black Max Units to Power and
the Machine Control.
When all Link Lite Black Max transmitter
and receiver units have been mounted, you
are ready to make electrical connections to
interface the Black Max(s) to power and
the machine control. Also, if remote
segment Black Max units are used, you
must connect the remote segment transmit-
ter unit to the main transmitter unit and the
remote segment receiver unit to the main
receiver unit with the cables provided.
3.5.1
Conduit Requirement s
The main Black Max transmitter and
receiver units both have a 7/8" hole to
accommodate a 1/2" conduit fitting. Run a
1/2" conduit from the machine control
enclosure to each main Black Max trans-
mitter unit. Similarly, run a 1/2" conduit
from the machine control enclosure to each
main Black Max receiver unit. All wires
required for the transmitter and receiver
should be pulled through the 1/2" conduit.
Use of flexible conduit with integral armor
and ground wire, such as Seal Tite, is
preferable. When such flexible conduit is
used, it is also desirable to route it in such
a way as to leave slack that will allow the
Black Max units to be moved further away
from the machine if future setups necessi-
tate moving the transmitter(s) and re-
ceiver(s) to meet safety distance require-
ments.
There are also two holes that are sized for
3/4" fittings, one in both ends of the main
transmitter and receiver units. These holes
are closed with screw in type plugs. They
should only be used for cable connections
between main transmitter and receiver
units and remote segment receiver and
transmitter units. DO NOT use the
plugged openings for conduit between the
main Black Max units and the control
enclosure. Use the open 7/8" hole only.
3.5.2
Power Connections
Both the transmitter and receiver units of
the Black Max must be supplied with 115
VAC (Nominal) power. Generally, this
power should be supplied from a trans-
former with 115 VAC secondary in the
machine control. Pull a "hot" wire, a
neutral wire, and a ground wire through the
conduit from the control enclosure to the
Black Max main transmitter unit. Refer to
Figure 3.13 for the location of the combi-
nation three connection power terminal and
plug in connector.
WARNING!
To prevent electrical
shock hazards lock all power to the
machine off before beginning the
wiring procedures for the Link Lite
Black Max. In the U.S., follow OSHA
Lockout regulations.
