Power connection 

 

The device only supports the voltage outlined in the type plate. Do not use any other power compo-

nents except those specifically designated for the switch device. 

 

Properly ground the device before connecting. Lack of a proper grounding setup may result in a safety 

risk and could be hazardous. 

 

Do not service equipment or cables during periods of lightning activity. 

 

Do not service any components unless qualified and authorized to do so. 

 

Do not block air ventilation holes. 

 

5.7.1

 

Grounding the device 

Electromagnetic Interference (EMI) affects the transmis-
sion performance of a device. By properly grounding the 
device to earth ground through a drain wire, you can 
setup the best possible noise immunity and emissions. 

 
 
 

5.7.2

 

Overview 

The switch can be powered by using the same DC 

source used to power other devices. A DC voltage range 
of 24 V or 48 

V DC

 must be applied between the V1+ ter-

minal and the V1- terminal (PWR1), see the following il-
lustrations. A Class 2 power supply is required to main-
tain a UL60950 panel listing. The chassis ground screw 

terminal should be tied to the panel or chassis ground.  

 

 

A redundant power configuration is supported through a 
secondary power supply unit to reduce network down 

time as a result of power loss. 

The switch supports 24 and 48 

V DC

. Dual power inputs 

are supported and allow you to connect a backup power 
source. 

 

 

 

 

 

The Terminal Block (CN1) is suitable for 14-22 AWG (0.35 - 2.5 mm

2

). Torque value 5,6 lb-in. 

 

The cross sectional area of the earthing conductors shall be at least 3.31 mm

2

 

Calculate the maximum possible current for each power and common wire. Make sure the power 
draw is within limits of local electrical code regulations. 

 

For best practices, route wiring for power and devices on separate paths. 

 

Do not bundle together wiring with similar electrical characteristics. 

 

Make sure to separate input and output wiring. 

 

Label all wiring and cabling to the various devices for more effective management and servicing.
