Power Supply Connection

The main power supply is connected to the terminal block at the lower left of the rear panel.
If a DC supply is being used, the polarity must be observed. The actual voltage specified
will be indicated in the System Drawings located in Appendix V of this manual. The
specified voltage must be used, and damage may occur if an incorrect voltage is applied.
The maximum wire size that the terminals will accept is 4 mm
There is one 6 mm earth stud at the rear of the TR-2100. The stud must be connected to a
main system earth with a suitable braided ground cable. This is required to ensure the safe
operation of the TR-2100.
Analogue & Digital Input Connections
The analogue input cables are connected to the orange strip connectors at the rear of the TR-
2100. The sequence of voltage and current transformer inputs must follow the User
Specification sheet. The maximum wire size for all analogue and digital inputs is 1.5 mm
(14 AWG). Smaller wire sizes can be accommodated using crimp terminations.
Voltage Inputs
The voltage inputs are connected directly to the standard 57 – 120V secondary windings of
protection or metering VTs. The actual nominal and full-scale voltages are given in the
System Drawings in Appendix V.
Figure 5 VT Wiring Options
Since all inputs are isolated from each other, either phase-to-phase or phase-to- neutral
windings can be connected.
