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

which 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 RENs of all equipment on a line should not exceed five

(5).

In the unlikely event that this equipment causes harm to the telephone network, the telephone company can

temporarily disconnect your service. The telephone company will try to warn you in advance of any such

disconnection, but if advance notice isn’t practical, it may disconnect the service first and notify you as soon as

possible afterwards. In the event such a disconnection is deemed necessary, you will be advised of your right to

file a complaint with the FCC.

From time to time, the telephone company may make changes in its facilities, equipment, or operations which

could affect the operation of connected equipment. If this occurs, the telephone company is required to provide

you with advance notice so you can make the modifications necessary to maintain uninterrupted service. This

product is not serviceable by the user.

Classification

UL 497A recognized, FCC

APC’s Modular Data Line Surge Protection System consists of the PRM24 Chassis, mounting hardware, ground wire, and

associated data line modules (PNETR5 for Network Protection, PTEL2R for Analog Telephone Protection, P232R for RS232
Protection,and PDIGTR for Digital Telephone Protection). The chassis was designed for use in any EIA-standard 19-inch (48.2

cm) wide equipment rack or enclosure.

This manual provides basic information necessary to install the chassis and associated modules in a rack or enclosure.

Procedures provided in this document are not intended to supercede local standards or codes. Reference the
Telecommunications Industries Association and Electronic Industries Alliance publication “Commercial Building,

Telecommunications Cabling Standard, General Requirements” (document number TIA/EIA-568-B.1-2001) to ensure proper

installation of system wiring.

The PNETR5 module will protect the port of a Network Interface Card, hub or other local area network

(LAN) equipment from damage caused by lightning-generated electrical transients. This module provides

surge protection for 10Base-T, 100Base-T4, 100Base-TX, 100VG or Token Ring Type 3 UTP port (RJ-45),

and VOIP applications. PNETR5 complies with applicable ISO/IEC Standard 8802-3 (IEEE 802.3) or 8802-

5 (IEEE 802.5) requirements. 
In applications where the network data transmission rate is high, insertion loss introduced by in-line devices

becomes a significant consideration where cable lengths are particularly long. At the 100 Mbp/s data

transmission rate, there is a small insertion loss introduced by the PNETR5. Use Table 1 to approximate the

insertion loss based on cable length effectively introduced by the PNETR5 by installed cable Category level

or type. The ISO/IEC 8802-3 standard specifies a maximum UTP cable length of 100 meters per segment at

10/100 Mbp/s. For Thinnet, the maximum cable length is 185 meters (607 feet).

The PTEL2R module protects analog telephones, ADSL, ISDN2, voice mail and

automated answering systems, fax machines and modems from damage caused by

lightning-generated electrical transients. Each PTEL2R protects up to 2 lines.

Warning:  Disconnect module wires before removing any module. Do not put fingers

or any object inside the chassis.
Model P232R (RS232 Protection)

The P232R module is for use with RS232 communication equipment (RS232

multiports, asynchronous multiplexers, asynchronous printer spoolers, etc.)

comprised of unshielded, twisted-pair wiring with RJ-45 connectors. It protects up to

four ports per unit. 
Model PDIGTR (Digital Telephone Protection)

The PDIGTR module is only for use in T1, CSU, DSU, ISDN, DDS and Digital

Leased Line telecommunication equipment, TNV-1 or SELV circuits only.

Safety
Caution: This equipment is intended to be used in a restricted access area and should only be

Chassis Installation and Grounding
APC recommends that the ProtectNET

TM

 Data Line Surge Protection chassis ( , 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   is provided on
the back of the chassis. Ensure the mounting rack or enclosure   is connected to a proper ground.
Install the chassis and modules   as shown in the illustration below.
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   by pulling it straight out from the 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 

, connect the input RJ-45 connector   to the signal source and then

to the upper connector on the module. Connect a data line cable 

 from the lower connector on

the module to the equipment to be protected. Note: To accomodate 24 modules, the four-wide
center blank panel   must be removed.
