Notes:
5
These relays contain bias magnets. Correct coil polarity must be observed.
6 Coil suppression diode is recommended for proper operation. Correct coil polarity must be observed.
7
Break before make not guaranteed.
8
Dot stamped on top of relay refers to pin #1 location. E-pin indicates Electrostatic shield pin. Unused pins omitted.
Pin numbers for reference only.
9
All models with Hg wet contacts are position sensitive, must be mounted within 30o of vertical plane. See schematic.
