MDE-4319A TopKAT Fuel Managment System Installation Manual · November 2005
Suction Pumps
The TopKAT System, with Mechanical Interface or Mechanical PCU options, is capable of
directly driving pump motors up to 3/4 HP at 115 VAC or 1-1/2 HP at 230 VAC. A starter
relay must be used with pump motors exceeding this limitation. A separate circuit breaker
should be supplied for each pump to meet the current requirements and to allow for isolated
control with the circuit breaker panel in case of problems.
Dispensers
The TopKAT System with Mechanical Interface option is capable of directly driving
submersible pumps up to 3/4 HP at 115 VAC or 1-1/2 HP at 230 VAC. A dispenser with a
submersible pump exceeding this limitation requires the use of a submersible starter relay. A
separate circuit breaker should be supplied for each dispenser in cases where it will directly
drive the submersible pump. Dispensers may be grouped together on a single breaker when
the submersible pump has its own breaker. It is recommended that no more than two
dispensers be powered from one breaker to maintain isolated control with the circuit breaker
panel in case of problems.
