Chapter 2: Wiring
The Ethernet Network LDT has three connectors.
The incoming power is supplied via a 4-pin M12-A
style connector. The Network communication will
be through either of the two 4-pin M12-D coded
connectors.
The LDT supports Star, Line and
Device Level Ring (DLR) topology.
Note: Any unused connectors should be covered
using our 04-521619 connector end cap.
2.1 Wiring Connections
Once the LDT has been installed, wiring connections
can be made. There are two groups of connections
you will need to make. They are as follows:
• Power Supply Connections (including ground
and shield)
• LDT Input/output Network Connections
Power Supply/Ground Connections
The incoming power cable is a 4-Pin, M12-A, Euro Style cordset. It has
4 conductors of 22ga, with a shield; these cables are available in either
Straight or Right Angle versions. To reduce electrical noise, the shield
must be properly used. When grounding the LDT, a single earth ground
should be connected to the power supply common. The LDT power
supply common should be connected to the power supply common (-)
terminal. On our Straight version cable the shield is tied to the cable's
coupling nut, and should not be connected to the controller's ground
(See figure 4-2 Grounding Connections). However, if you are using one
of our 949-044LXX Right Angle version cables, the cables shield is not
tied to the cable's coupling nut, in this case it is recommended to tie
the shield to the power supply common.
insulated and tied back.
On corsets where the shield is tied to the coupling nut, the LDT's shield
should NOT be tied to the earth ground at the power supply (See figure
4-2 Grounding Connections).
In order for the Network LDT to operate properly, the LDT's external
power supply must provide a voltage between +7 to +30 VDC. Each
LDT will draw approximately 3 watts of power. The power supply must
be rated at 150mA minimum. The power supply should provide less
than 1% ripple and 10% regulations. (The power supply should be
dedicated to the LDT to prevent noise from external loads from affecting
the position readings.) It is preferable that the cable between the LDT
and the power supply be one continuous run. If you are using a junction
box, it is highly recommended that the splice junction box be free of
AC and/or DC transient-producing lines. The shield should pass straight
thru this enclosure and not tied to ground.

Network Connections
The Network communication will be two 4-pin M12-D coded connectors.
Our Network LDT supports Star, Line & DLR topology.
These connections will require M12-D cables; these are available in
either Straight or Right Angle versions, as well as M12-D on one end
and RJ45 on the other. All cables have 4 conductors of 24ga, with an
aluminum/polyester/aluminum foil with an overall braid of tinned copper
shield. These cables meet the Requirements of TIA/EIA568-C, Category
5e Cable for 10 and 100 Base-T Ethernet. Always observe proper
grounding techniques such as single point grounding and isolating high
voltage (i.e. 120/240 VAC) from low voltage cables, whenever possible.
WARNING:
!
Network LDT cables near high voltage sources.
