ISOTROL CONTROL BOX WIRING PRECAUTIONS
WARNING! This device is intended to provide electrical isolation between the dispenser pump enable (Hook) signal and the
submersible turbine pump (STP) control relay. Other energized sources of power can still exist within the dispenser even
with this device. The neutral connection to the N terminal of TB1 and N terminal of TB2 must be from the service panel and be
a permanently connected, unswitched connection.
The N connection on TB1 and the eight N connections on TB2 may be spliced to a common neutral wire from the service panel
described above.
Make only one "wire" connection on each N terminal on TB2.
CAUTION! The phase of L1 (TB1) must match the phase of the power supplying the ATG device in order to prevent cross phasing
which may damage the input on some ATG equipment.
GENERAL WIRING PRECAUTIONS
Wiring must be rated 90°C minimum.
Make ground connection in accordance with local codes.
