General Information
Other Considerations
• Do not install this device in an environment where the operating temperature exceeds 0 to 40oC (32 to 104oF).
• Do not install this device where the relative humidity exceeds 95%, non-condensing.
• Do not store this device in an environment that exceeds 0 to 45oC (32 to 113oF).
Chassis Installation and Grounding
APC recommends that the ProtectNet Data Line Surge Protection chassis ( 1 , Figure 1) PRM24, be installed using the mounting hardware provided with the chassis.
Additionally, the chassis must be connected to a proper protective earth ground. A ground stud 2 is provided on the back of the chassis. Ensure the mounting rack or
enclosure 3 is connected to a proper ground. Install the chassis and modules 4 as shown in Figure 1.
Module Installation
The system chassis is designed to accomodate up to 24 data line modules.To install a module, remove one of the blank panels
chassis.Align the module with the groove in the chassis, and slide the module fully into the chassis.

Cable Installation
To install a data line cable 6 , connect the input RJ-45 connector 7 to the signal source and then to the upper connector on the module. Connect a data line cable
lower connector on the module to the equipment to be protected.
Note: To accomodate 24 modules, the four-wide center blank panel 9 must be removed.

Module Information
Model PNETR5 and PNETR6 (Cat5 and Cat6 Network Protection)
The PNETR5 and PNETR6 modules protect the ports of a network interface cards, hubs or other local area network (LAN) equipment from damage caused by electrical transients over a Cat5 or Cat6 data line. These modules provide surge protection for 10Base-T, 100Base-T4, 100Base-TX, 100VG or Token Ring Type 3 UTP port (RJ-45), and
VOIP standards and applications. Both modules comply with IEEE 802.3 and IEEE 802.5. PNETR6 is also compatible with 1000Base-T/Cat6 and IEEE 802.12 Ethernet
standard, Cat5 and Cat6. PNETR5 and PNETR6 key specifications are listed below.

Module Information - Continued
Module Information - Continued
Model PNETR5 - In applications where the network data transmission rate is high and cable lengths are long,
insertion loss introduced by in-line devices is a major consideration. At the 100 Mbp/s data transmission rate
there is a small insertion loss introduced by the PNETR5. Use Table 1 below to approximate the insertion loss
introduced by the PNETR5 based on your installed cable type. The ISO/IEC 8802-3 standard specifies a
maximum UTP cable length of 150 meters per segment at 10 and 100 Mbp/s. For Thinnet, maximum cable
length is 185 meters (607 ft.).
Model P232R (RS232 Protection)
Federal Communications Commission (FCC) Notice
The P232R module is used for RS232 communications (RS232 multiports, asynchronous multiplexers,
asynchronous printer spoolers) using unshielded, twisted-pair wiring with RJ-45 connectors. It protects up to
four ports per unit.
This equipment contains an FCC compliant RJ-45 modular jack. It is designed to be connected to the telephone
network or premises wiring using compatible modular plugs and cabling, which comply with the requirements of
FCC Part 68 rules. The Ringer Equivalence Number (REN) is used to determine the number of devices that may be
connected to the telephone line. An excessive REN may cause the equipment to not ring in response to an incoming
call. In most areas, the sum of the RENs of all equipment on a line should not exceed five (5).
Model PNETR6 - Applications where the network data transmission rate is high and cable lengths are long,
an insertion loss is introduced by in-line devices. At 250 Mbp/s there is a small insertion loss introduced by
the PNETR6. Use Table 1 below to approximate the insertion loss based on the installed cable type. The ISO/
IEC 8802-3 standard specifies a 150 meter maximum UTP cable length per segment at 250 Mbp/s.
