955S 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 Connections
Power Supply/Ground Connections
The 955S standard cable is a 4 Pin, 12mm, Euro Style
cordset. It has 4 conductors of 22ga, with an aluminum/
polyester/aluminum foil with drain wire. Cable O.D. is
.250. To reduce electrical noise, the shield must be
properly used. Connect the cable’s shield to the controller
system GND.
Always observe proper grounding techniques such as
single point grounding and isolating high voltage (i.e.
120/240 VAC) from low voltage (10-30 VDC cables).
Whenever possible, this cable should be run in conduit
by itself. The power supply common, the cable shield and
a good earth ground should be connected together at the
location of the power supply common.
WARNING
Do not route the BRIK output cable near high
voltage sources.
In order for the 955S to operate properly, the LDT’s
external power supply must provide a voltage between
+10 to +30 VDC. The power supply must be rated at
100mA 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 BRIK.)
