Thank you for purchasing APC’s Line-R Automatic Voltage Regulator! Please fill out and mail the
product warranty registration form, or fill out an online form at www.apc.com.
Chronically abnormal line voltage is often the result of adjustments made to the power station to conserve
energy, or to compensate for low voltages in other areas. Locally, the operation of heavy loads such as air
conditioners, office copiers, and laser printers may cause temporary voltage fluctuations.
The Line-R is a high-performance, microprocessor-controlled tap changing device which automatically
corrects brownouts (by boosting low voltage) and overvoltages (by stepping down high voltage) from the
power utility service to levels that are safe for computers, as well as other sensitive equipment. APC’s
Line-R provides the highest degree of protection from line voltage sags and swells, and has been designed
for many years of reliable, maintenance-free service.
Please Read This Manual
This manual provides safety, installation and operation instructions that, when followed, will ensure the
fullest performance and service life that the Line-R can provide. Please save this manual. It includes
important instructions for the safe use of this product, as well as information necessary to obtain factory
service, if necessary.
Applications
CAUTION: The total power consumption of all equipment plugged into the Line-R must not exceed 300
W or 300VA. A total load in excess of 300 W or 300 VA will cause the fuse to fault (blow).
The Line-R is designed for use with voltage sensitive equipment such as: a home computer, monitor,
inkjet printer, scanner or fax. It is also designed for use with home electronics equipment such as
televisions, stereos, CD players, VCRs, and DVD players, data processing equipment, modems,
typewriters, calculators, and telephone equipment.
Appliances not suitable for use with the Line-R are items such as refrigerators, freezers, power tools, air
conditioners, dehumidifiers, blenders, or any device that employs an AC motor for operation.
Not for use
with small fuel generators.
Also excluded are life sustaining equipment and any device with a power
requirement of 300 W or 300 VA.
When using the Line-R with an Uninterruptible Power Supply (UPS), connect the UPS to the Line-R’s
output, then connect the Line-R to the wall outlet.

• Connect Your Equipment
Plug equipment into the Line-R rear-panel outlets and switch the equipment ON. The equipment will not
be powered until the Line-R is switched ON.
CAUTION: The total power consumption of all equipment plugged into the Line-R must not exceed
300 W or 300 VA. A total load in excess of 300 W or 300 VA will cause the fuse to fault (blow).
CAUTION: Do not plug an LE300 into a 220 volt outlet as this may damage the unit or the connected
equipment.
Switch ON the Line-R
Switch the Line-R ON by pressing the front panel ON/OFF switch to the ON (l) position. This switch
may be used as the master ON/OFF switch for all equipment connected to the unit.

Installation
• Inspection
Remove the Line-R from the shipping container and inspect it for damage that may have occurred in
transit. Notify the carrier and place of purchase if any damage is found. The packing materials are made of
recyclable materials and should be saved for reuse or be disposed of properly.
•Placement
Please install the Line-R in a protected environment.
Do not block the top or side air vents on the unit. Allow 2.5 cm (1 inch) minimum vent clearance.
Do not operate the Line-R in an environment where the ambient temperature or humidity is outside the
limits listed in the Specifications section of this manual. Operate the Line-R in an environment free of
excessive dust, mechanical vibration, inflammable gases and explosive or corrosive atmospheres.
• Plug the Line-R into Wall Outlet
Plug the Line-R (LE300) into a 115 volt AC wall outlet.

Fuse Replacement
For safety purposes, the Line-R provides a user-
replaceable fuse to protect the unit from being
overloaded. See the Specifications table for
replacement fuse rating. Replace a faulted fuse
with a fuse of the same exact type and rating.
CAUTION: Unplug the Line-R from the wall
outlet before replacing the fuse.
Polarization Standard
In order to comply with all installation practices
and standards, as well as to avoid the risk of
electrical shock, the Line-R must be connected
in places having proper grounding. The network
phase conductors where your equipment will be
connected must be protected by fuses or circuit
breakers, and it must be bipolar if used in a
biphase network.
