From: 208/230 Volt, Three Phase, Electrical Power Source,
utilizing two lines to power a Single Phase load.
(See Note 1)
NOTES:
1) Only use phases L1 & L2, or L3 & L2. DO NOT use
phase L1 & L3.
2) Install the 1uF Line Filter Capacitor (INCON PN 020-0028)
between AC input line terminals at the Relay Box.
3) The TS-LLD is installed at the submersible pump housing
(see Chapter 2.2 for details).
4) Follow your local and National Electrical Codes for
electrical grounding requirements.
5) 230 VAC must not enter the Control Unit! All Control Unit
AC wiring must be 110 volts (110V power = TB 1-1, dispenser
switch [ S2 ] on signal = TB 1-4, and pickup coil [ M2 ] sense
lead all must be derived from the same phase [ L2 ] ).
