3600 Modem Hardware Update
DC Power Connector
Overview
This document contains instructions for installing the 3600 modem
equipped with DC input supply voltage. This information should be used for the
3600 DCV version and replaces the power supply installation section in the
standard 3600 modem user's guide.
DC Power Connection
The 3600 modem is available with an optional DC power connector on
the back panel. This connector accepts a DC voltage source from 10 to 53 VDC and
provides 500 Volts isolation. Figure 1 shows this connector.

DC Power Supply Specifications
3600 modems equipped with a DC power connector come with a grounded power
cable for attaching the modem to an acceptable DC power source. To attach this
cable to the DC power connector on the back panel of the 3600 modem:
§
Connect the positive wire from the supplied cable to the positive terminal
block (labeled +) on the DC power connector. Facing the back of the modem,
this is the left terminal block.
§
Connect the negative wire from the supplied cable to the negative terminal
block (labeled –) on the DC power connector. Facing the back of the modem,
this is the middle terminal block.
§
Connect the ground wire from the supplied cable to the earth ground terminal
block (labeled with earth ground symbol) on the DC power connector. Facing the
back of the modem, this is the right terminal block.
Note: Connecting the ground wire to earth ground is optional for operation.
However, it is strongly recommended that you make this connection because doing
so provides surge protection for the modem.
