Meeting Electrical and Environmental Requirements
Environment
The signal generator is designed for use in the following environmental conditions:
• indoor use
• <15,000 feet (4,572 meters) altitude
•0 to 55° C temperature, unless otherwise specified
• 80% relative humidity (maximum) for temperatures up to 31° C, decreasing linearly to 50%
relative humidity at 40° C
CAUTION This product is designed for use in INSTALLATION CATEGORY II and POLLUTION
DEGREE 2, per IEC 61010 and 664, respectively.
Ventilation
Ventilation holes are located on the left side of the signal generator cover and the rear of the signal
generator chassis. Do not allow these holes to be obstructed, as they allow air flow through the signal
generator.
When installing the signal generator in a cabinet, the convection into and out of the signal generator
must not be restricted. The ambient temperature outside the cabinet must be less than the maximum
operating temperature of the signal generator by 4° C for every 100 watts dissipated within the
cabinet.
CAUTION Damage to the signal generator may result when the total power dissipated in the
cabinet is greater than 800 watts. When this condition exists, forced convection must be
applied.
Line Settings
The signal generator has an autoranging line voltage input. The available ac power source must meet
the following conditions:
Voltage: 100/115 volts nominal (100- 120 volts)
230/240 volts nominal (220- 240 volts)
Frequency: for 100/115 volts: 50/60 (400 Hz nominal E8257D and E8663D only)
for 230/240 volts: 50/60 Hz nominal
Power: E8257D and E8663D PSG analog models: 350 watts maximum
E8267D PSG vector models: 450 watts maximum
CAUTION Damage to the signal generator may result if the supply voltage is not within the
specified range.
