Connecting to a Voltage Source

The back panel of the modem provides a 2-position screw terminal power interface

connector. For your convenience, the DC voltage of the input power is non-polarized. To

meet your specific application, the modems can be powered from the following power

sources:

y Model DSP19.2 (with AC-DC power converter): 90 to 265 Volts AC, 50 to 60 Hz,

single phase or 100 to 400 VDC. The output of the converter is a 12 VDC source

that will power the modem.

y Model DSP19.2-LV (DC version): 10 to 60 Volts DC. The model DSP19.2-LV

comes with a power cord for making this connection.

Figure 2-2 on page 10 shows the connection to the Model DSP19.2FP’s power interface

shows the connection to the Model DSP19.2-LV’s power interface.

WARNING:

Before you connect a voltage source, observe the following power supply

voltage guidelines. Otherwise, you will void your warranty if the wrong voltage

is applied.

y Be sure the voltage source is within the permitted ranges shown

above. Otherwise, your modem and any attached devices may be

damaged.

y Customer-supplied cables must be suitable for the site

environmental conditions.

y Screw terminals on the power interface accept 24 to 16 AWG.

However, surge protection is effective only if there is a solidly

earthed ground connection greater than 18 AWG.

y Be sure the power source is not controlled by a wall switch, which

can be inadvertently turned off, shutting off power to the modem.
