Specifications and Application
•
Specifications and ordering information are in the Power Express Class 2 Distribution Brochure available at
•
External Surge Protective Devices (SPD)
•
Evaluated surge withstand
-
1000V, 10/1000 µs pulse.
•
Primary protection or other surge protection devices are required on each input where the transient over voltage due to
atmospheric discharge and faults in power distribution systems exceeds these levels.
•
For example, external SPDs are required when the product is used with outdoor overhead wiring.
•
Equipment and subassembly ports:
are suitable for connection to intra
-
building or unexposed wiring or cabling;
can be connected to shielded intra
-
building cabling grounded at both ends.
•
Grounding / Bonding Network –
Connect to an Isolated Ground Plane (Isolated Bonding Network) or an Integrated
Ground Plane (Mesh Bonding Network or Common Bonding Network).
•
Installation Environment
-
Install in Network Telecommunication Facilities, OSP, or Restricted Access location.
•
Equipment must be permanently connected.
•
DC return may be either Isolated DC return (DC
-
I) or Common DC return (DC
-
C).
•
Either DC Output polarity (Out+ or OUT
-
) must be externally connected to DC Reference Ground (CO Ground).
