User Manual for PTEL1-4

1. Introduction

Thank you for purchasing this American Power Conversion 4-

line telephone surge protector, model PTEL1-4. It protects tele-

phones, voice mail and automated answering systems, fax ma-

chines and modems from damage caused by lightning-generated

electrical transients. Each PTEL1-4 protects up to 4 lines. PTEL1-4

includes grounding cables and wall mount/stacking brackets. See

figure 1. Use as many PTEL1-4s as needed to protect your systems.

Up to 10 PTEL1-4s can be rack mounted using the APC rack mount-

ing kit, part number PRM, available from your dealer or from

APC at 1-800-800-4APC (or 1-401-789-5735). See Figure 2 for

optional rack mount configuration.

Please fill out and return the enclosed warranty registration card.

2. Safety

Please read and save these instructions, and take the following

safety precautions.

n Use the PTEL1-4 in a protected environment only.

n Never install telephone wiring during a lightning storm.

n Follow the installation instructions carefully. The current-

limiting feature in this product could be rendered inoperable

if the product is improperly installed.

n To fully protect the user and equipment, the product must be

connected to a proper ground, as described in section 3.

3. Installation

Setting up the ProtectNet

1. Refer to figure 3. Using telephone cords, connect the PTEL1-4

IN jacks to the nearest phone wall outlets ➀.

2. Connect the devices to be protected (e.g. modem or fax ma-

chine) to the PTEL1-4 OUT jacks ➁.

3. Connect the PTEL1-4 ground wire terminal to a proper ground

(protective earth) ➂ as described in the section on grounding

below.

4. The PTEL1-4 can be placed on a flat surface, mounted on a wall,

stacked, or mounted on the optional rack shelf. See figure 4 for a

typical rack mount installation. See figure 5 for a typical surface

installation.

Grounding the ProtectNet

1. Verify that the protected equipment is plugged into a three-wire

grounded outlet, if applicable. If your site has outlets with only

two holes (no center ground), a qualified electrician should be

called to upgrade your building wiring. Many APC UPS and surge

suppression products have a Site Wiring Fault Indicator that warns

of improper building wiring, including lack of a safety ground. An

outlet wiring tester can be purchased at most hardware stores,

though it is not as sensitive. Use of APC power protection equip-

ment is recommended.

2. For ganged, stacked, or rack mounted units connect the sup-

plied short grounding wire from PTEL1-4 to PTEL1-4 daisy chain

fashion. Then use the supplied long ground wire to make the ground

connection. Ground the PTEL1-4 by choosing one of the follow-

ing measures, listed in order of preference. Do not ground to the

rack mount shelf.

n Many APC UPSs provide a TVSS Ground screw for fasten-

ing the ground terminal. Use this screw wherever possible.

Again, verify that the UPS is plugged into a three-wire

grounded outlet.

n Fasten the ground wire to the phone system ground, if pos-

sible, or beneath the head of a metal screw on the chassis of

the protected equipment. Do not loosen chassis screws that

secure internal components.

n Fasten the ground terminal beneath the head of a wall outlet

cover plate (120V systems only). Where possible, this should

be the same outlet where your protected equipment is plugged

in.

CAUTION: Disconnect power to the outlet by removing the branch

fuse or switching off the circuit breaker before attempting to

loosen the cover plate screw. Do not overtighten the screw.

n Fasten the ground terminal beneath a clamp secured around

a cold water pipe.
