ISOTROL CONTROL BOX WIRING PRECAUTIONS
The Isotrol Control Box 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.
The phase of L1 (TB1) must match the phase of the power supplying the ATG device 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.
