Prepare the Laboratory
The following sections describe requirements for your Thermal Analysis System. Make sure
your laboratory meets all of the requirements before you try to install the system. You should
step through the topics in the order presented below.
Before starting installation, please read the Safety and Regulatory Information.

Electrical Requirements
Power Source
An independent power source should be provided for the system, including the computer.
The power source should not be associated with heavy-duty equipment such as large motors,
or with possible sources of high-frequency interference such as photocopying systems,
discharge lamps, or radio transmitters. The power supply should be fused at a maximum of
20 A (120 V systems) or 16 A (200–240 V systems).
Line Voltage
PerkinElmer analyzers and their associated instruments are designed to operate within a line
voltage range of 10% of the nameplate voltage or other such voltage selected at installation
to suit the particular country or region. (The range for 240 V systems is +6%, –10%.) The
supply must be smooth, clean, earthed and free of transient voltages over 40 V.
The frequency range is ±1% for 50 Hz and 60 Hz systems.
Instrument Maximum Power Requirements
Refer to the Safety Precautions for the instrument.
Environmental Requirements
You must provide the following laboratory conditions for your Thermal Analysis System:
• A clean area, free from vibration and strong magnetic fields.
• An adequate and stable power source for all system components.
•
The area must have a relative humidity of 20–75% (without condensation).
•
For optimum performance, the temperature of the area should be between 10 °C and
35 °C (50 °F and 95 °F).
• The instrument will operate safely between 5 °C and 40 °C.
• Place the system components in an area that is not in direct sunlight or direct contact
with heating and cooling ducts or units.
