INSTALLATION
WARNING !
See Special Conditions of Safe Use in the folllowing section regarding
ATEX, UKEX & IECEx Certification Information before installation
The 12V/24V supply to the module connects via screw terminals 1 + 2 as shown
above.
As the 9478 Ethernet Isolator supports Auto MDI/MDI-X, a straight connected RJ45
Cat5e cable is used to connect to any device on both the Safe and Hazardous Area
ports.
Both the Safe and Hazardous RJ45 ports have integrated Ethernet switches sothat
each side will auto-negotiate speed and link independantly of each other.
It is recommended that Cat5e cables for Hazardous Area Zone 1 use are ‘Blue’ in
colour and are of good quality (see accessories section), the Safe Area cables being a
colour other than blue to aid identification.
The operating parameters must not exceed those as detailed on the certificate.
This apparatus must only be installed or replaced by a competent person who must
ensure that existing IS segregation is maintained.
