High Voltage: All M-2026 input terminals will withstand 1500 Vac RMS to

chassis or instrument ground for one minute with a leakage current not to

exceed 25 mA, for all terminals to ground. The M-2026 output terminals will

withstand 500 Vac RMS to chassis or instrument ground for one minute with

a leakage current not to exceed 25 mA, for terminals to ground.

Input and output circuits are electrically isolated from each other, from other

circuits and from ground.

Radiated Electromagnetic Withstand Capability: All units are protected against

electromagnetic radiated interference from portable communications transceivers.

Environmental
