SmartSwitch 2200 DC POWER SUPPLY INSTRUCTION SHEET
This document provides additional information to the SmartSwitch 2200 user’s guide shipped with your device. This
document describes how to connect the dc version of a SmartSwitch 2200 device to 48 or 60 Vdc (48/60 Vdc) power
sources. Except for special grounding considerations for a particular type of rack installation and the two dc power
supplies, the device is installed and functions the same as the ac version. The two dc power supplies in the device have
their own on/off switch and input power strip, and are each rated at 125 watts. The on/off power switches and input
power strips are similar to the ones shown in Figure 1.

DC POWER SUPPLY REQUIREMENT
Input power can be 48 or 60 Vdc with a maximum current drain of 4.9 A for each power supply.
INSTALLATION REQUIREMENT
Each dc power supply input requires either a 48 Vdc or 60 Vdc power source supplied by three 18 AWG (American
Wire Gauge) copper wires. These wires must be terminated with either ring or spade terminals that accept a #6 screw.
ONLY QUALIFIED PERSONNEL SHOULD PERFORM THESE INSTALLATION PROCEDURES.
TO REDUCE THE RISK OF ELECTRIC SHOCK OR ENERGY HAZARDS:
•
CONNECT TO A RELIABLY GROUNDED 48/60 VDC SELV SOURCE.
•
ENSURE THE BRANCH CIRCUIT OVERCURRENT PROTECTION IS RATED AT A MINIMUM
OF 15 A.
•
USE 12 or 14 AWG SOLID COPPER CONDUCTORS ONLY.
•
ENSURE THAT A READILY ACCESSIBLE DISCONNECT DEVICE THAT IS SUITABLY APPROVED
AND RATED, IS INCORPORATED IN THE FIELD WIRING.
TO BE INSTALLED IN A RESTRICTED ACCESS AREA IN ACCORDANCE WITH THE NEC OR THE
AUTHORITY HAVING JURISDICTION.
