Model S4000T
9
It is recommended that a three-wire shielded cable be used for making power and
output signal connections on the Model S4000T. The terminal block accepts 14 AWG
to 20 AWG stranded or solid wire. Each wire should be stripped before wiring the
Model S4000T Intelligent Sensor. To connect wiring to the terminal block, insert a
screwdriver into the orange tab and press down (Figure 15), opening the terminal.
Insert the wire into the terminal and release the orange tab, clamping the wire in the
terminal. Check the hold of the wire by GENTLY tugging it to ensure it is locked in.

NOTE -
Up to 14 AWG wire can be used if it is carefully stripped (Figure 16).
3.5.3 DC Power and Ground Connections
Primary DC power must be provided by the customer, unless one of the following
General Monitors Modules is being used with the Model S4000T:
•
DT210 Eight-Channel Readout/Relay Display Module with Power Supply & Relay
Module
•
DT230 Dual-Channel Readout/Relay Display Module
•
TA202A Trip Amplifier Module with a PS002
The following General Monitors Modules provide power connections for the Model
S4000T, but need a customer supplied DC source:
•
DT210 Eight-Channel Readout/Relay Display Module without a Power Supply &
Relay Module
•
DT220 Dual-Channel Display Module
•
TA202A Trip Amplifier Module without a PS002
Since the Model S4000T is designed to operate continuously, a power switch is not
included, in order to prevent accidental system shutdown.
NOTE -
Power must remain disconnected until all other wiring connections have
been made.
