APPENDIX A: CONNECTORS

MAXIMUM VOLTAGE/CURRENT. The maximum voltage

that may be applied to any connector on the M220 is 200

VDC, 125 VAC rms, or 175 VAC peak--these limits apply

only if the product is installed in a humidity-controlled

(<60% RH) environment where airborne contaminants and

transients are controlled, and there is NOT a relay

connection made to power mains. If these conditions

CANNOT be maintained, then the maximum voltage is 60

VDC, 43 VAC-rms or 68 VAC-peak.

The maximum current (non-inductive) that may be applied to

the M221 is:

Per Switch: 1 ADC, 1 AAC peak, 40W DC, 40VA AC

Per Module: 100W DC, 100VA AC
