Important Safety Instructions
• WHEN REPLACING BATTERIES, USE THE SAME QUANTITY AND TYPE OF BATTERIES:
SEALED LEAD-ACID MAINTENANCE FREE:
PTM280VA: 1 x 7AH/12V
PTM420VA: 1 x 7AH/12V
PTM650VA: 1 x 11AH/12V
PTM1KVA: 3 x 11AH/6V
• PROPER DISPOSAL OF BATTERIES IS REQUIRED. PLEASE REFER TO YOUR LOCAL CODES
FOR DISPOSAL REQUIREMENTS.
• THE UPS CONTAINS VOLTAGES WHICH ARE POTENTIALLY HAZARDOUS. ALL REPAIRS
SHOULD BE PERFORMED BY QUALIFIED SERVICE PERSONNEL.
• THE UPS HAS ITS OWN INTERNAL ENERGY SOURCE (BATTERY). THE OUTPUT
RECEPTACLES MAY BE LIVE EVEN WHEN THE UPS IS NOT CONNECTED TO AN AC
SUPPLY.
For safe and continuous operation of the UPS depends partially on the care taken by users. Please observe
the following precautions.
• Do not disassemble the UPS.
• Do not attempt to power the UPS from any supply, other than a 3-wire grounded source.
• Do not place the UPS near water or in environments of excessive humidity.
• Do not block the air vents on the side of the UPS.
• Do not plug appliances, such as hair dryers, into the UPS sockets.
• Do not place the UPS under direct sunshine or close to heat-emitting sources.
• This UPS is intended for installation in a temperature controlled, indoor area free of conductive
contaminants.

Installation and Operation Manual
1. Introduction
1.1 Overview
PC-Power is an advanced line-interactive Uninterruptible Power System (UPS), designed to protect sensitive
equipment, such items as computers, telecommunication systems, and computerized instruments, from
spikes, surges, saps, transients and blackouts.
When mains is present, the UPS filters small fluctuations continuously. When mains fails, the UPS uses its
internal battery to supply back-up power.
1.2 Smart Buck and Boost Line Conditioning
The standard European nominal mains voltage is 230V. The actual mains voltage can fluctuate above or
below this nominal value. To protect sensitive loads from such mains fluctuations, the UPS provides line
conditioning using both buck (step-down voltage) and boost (step-up voltage) functions.
The line conditioning feature allows the UPS to provide protection over a wider mains voltage range
without drawing power from its internal battery.
1.3 User Replaceable Battery Design
The internal battery is the most critical component in the UPS. It has a design life of between 3-5 years.
With a PC-Power UPS, the battery can be replaced by the user, even in hot mode.
1.4 Advanced Computer Interface
PC-Power UPS provide complete RS232 and volt-free contact interfacing.
Using the UPS monitoring and shutdown package, OptiSafe, a user can use a computer screen to determine
the input/output voltage and current, frequency and battery voltage, etc, and analyse power problems.
1.5 User Configurable Settings
The operating parameters of a PC-Power UPS can be adjusted to suit the characteristics of its site.
