Notes:
1
Consult factory for life expectancy at other switching loads. Resistance >0.5Ω denes end of life or failure to open.
2
Break-before-make action on Form C Model 2341 is not guaranteed. Consult factory if break-before-make is required.
3
Electrostatic shield (2332 & 2341 only) is connected to pin #6. Coaxial shield is connected to pins #6 and #7.
4
is relay is polarity sensitive. Pin #3 MUST be positive.
