Safety Protection

Mains Input

.......................................................

IEC 61010-1, Overvoltage Category II, Pollution Degree 2

Measurement Front Panel

................................

IEC 61010-2-030: CAT II 300 V

Measurement Rear Panel

.................................

IEC 61010-2-030: CAT II 150 V CAT II, 250 V rms with maximum

transient voltage of 1000 V peak. These terminals are not intended for

connection to mains voltage above 150 V without external transient

suppression. The maximum input that can be applied between rear-

module terminals or between any rear-module terminal and earth

ground is 250 V dc or ac rms.

Electromagnetic Compatibility (EMC)

International

........................................................

IEC 61326-1: Basic Electromagnetic Environment

CISPR 11: Group 1, Class A

Group 1: Equipment has intentionally generated and/or uses

conductively-coupled radio frequency energy that is necessary for

the internal function of the equipment itself.

Class A: Equipment is suitable for use in all establishments other

than domestic and those directly connected to a low-voltage power

supply network that supplies buildings used for domestic purposes.

There may be potential difficulties in ensuring electromagnetic

compatibility in other environments due to conducted and radiated

disturbances.

Emissions that exceed the levels required by CISPR 11 can occur

when the equipment is connected to a test object.
