MAXIMUM VOLTAGE/CURRENT: The maximum voltage
that may be applied to any connector on the E2273A is
200 VDC, 141 VAC rms, or 200 VAC peak. These limits
apply only if the product is installed in a humidity-con-
trolled (<60% RH) environment where airborne contami-
nants and transients are controlled, and there is NOT a
relay connection made to power mains. If these condi-
tions CANNOT be maintained, then the maximum volt-
age is 60 VDC, 48 VAC rms or 68 VAC peak.
The maximum current (non-inductive) that may be
applied to the E2273A is 1 ADC, 1 AACpeak per switch.
Maximum power is 40W DC, 40VA AC per switch; 100W
DC, 100VA AC per M-Module.
