GROUNDING
To ensure proper operation of the equipment and provide the necessary safety factors, this unit
must be grounded. A ground wire (preferably green) must be connected between the ground
terminal position of a remotely-mounted Electric Keytrol, and the main electrical service panel.
When the Keytrol is factory-mounted to a pump or dispenser, the pump or dispenser must be
properly grounded. One (1) earth ground connection is required per unit. The ground rod is to be
a solid, corrosion-resistant conductor and must be installed at the main electrical panel in
accordance with the National Electrical Code. It should be properly tied into the ground bus strip
of the panel. We recommend the neutral and ground bus strips be bonded together (unless
prohibited by local codes).
CIRCUIT BREAKERS
Power to the unit should be supplied from a dedicated breaker. No other equipment should be
powered from this breaker. Units directly driving pumps (suction or submersible) should be
supplied power from a separate breaker. A tag on the motor identifies the maximum current draw
of the motor. If two (2) pumps are supplied from one breaker, that breaker must be capable of
handling the load of both motors. In cases where multiple remote dispensers supply power to a
single submersible pump, all breakers controlling the remote dispenser must be on the same
phase of power. Failure to do this will damage the equipment. Provisions must be made to break
both legs of any AC circuit.
VOLTAGE REQUIREMENTS
This unit must be supplied with at least 105VAC (210VAC for 230VAC units) to ensure proper
operation. Power should be checked between positions 7 and 8 (H and N or L1 and L2) of the
main terminal block in the Keytrol housing while the pump is idle and running in bypass. If the
power drops below the minimum allowable levels during either of these operation modes, the
Keytrol controls may not function properly.
