Notes:
These relays contain bias magnets. Correct coil polarity must be observed. 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.
