Grounding Procedure and Regulatory Information
Note:
All bullets must be followed for regulatory compliance.
•
All cables connected to the IPSDC must be shielded with
shield terminated as shown in
. Use #8-32 SEMS
screws provided.
•
When wiring readers, ground the shields of the cable at the
IPSDC enclosure grounding studs to avoid electrical noise.
•
The IPSDC enclosure must be connected to the nearest
earth ground. (See
•
A convenient earth ground, such as an electrical box or a
ground bus, must be provided to the IPSDC enclosure.
•
The earth ground connection must be made to the terminal
lug provided. Mount the terminal lug to the PEM nut on the
bottom of enclosure using the #8-32 SEMS screw provided,
as shown in
. Use #14-18 AWG wire.
•
Before connecting the network cable to connector J10, loop
the cable through ferrite provided as shown in
Note:
Ferrite must be installed inside of the enclosure.

Connecting the Power
The IPSDC provides two methods of connecting power, both of
which are sold separately:
•
Network connector J10 as PoE. (See
).
•
Auxiliary power connector J8 with network hub POE device or
24 VDC supply with battery backup (

Using PoE
Not evaluated by UL.
1.
Install a PoE supply (IEEE802.3af 16 watt Class 0 Mode A or
B PoE Power Sourcing Equipment (PSE)) in accordance with
the manufacturer's instructions.
2.
By Ethernet standards, the maximum cable length is limited
to 328 ft. (100 m) between the PoE source and the IPSDC.
3.
Attach supplied ferrite to the network cable by looping the
network cable through the ferrite as shown in
4.
Connect the network cable to connector J10 on the IPSDC.
5.
Connect the other end of the network cable to the PoE supply
per the manufacturer’s instructions.
