Output Connections - Ametek 2003RP User And Programming Manual

3.6 Output Connections

All load connections must be made at the terminal block on the rear panel. The remote
sense inputs allow the power source output voltages to be monitored directly at the load and
must be connected for all three phases. The remote sense wires are connected to adjacent
pins for each phase on the rear panel output terminal strip.
Because of the possibility of hazardous voltages on the output terminals, insulation of wiring
on the output must be rated for the maximum output voltage of the source, at least 270
volts. There must be no accessible live part connected to the 2003RP output terminals. See
Figure 3-6.
The output power cables must be large enough to prevent a voltage difference greater than
7% of the programmed value from the power output pins to the sense input pins. Table 3-1
shows the maximum length of the output wires allowing 1 per cent voltage drop. The table
assumes the Remote Sense input is connected at the load. For 2003RP models with lower
voltage ranges than 135 V , the wires may have to be made larger. Numbers shown in
RMS
Table 3-1 are for standard a 2003RP model with 135 V range.
