A licensed electrician must supervise the electrical connections. The dimension drawings show the area suitable for
incoming power and motor connections. No other location shall be used. Only watertight hub fittings shall be used
when entering the cabinet to preserve the NEMA rating of the cabinet. The installer is responsible for adequate
protection of the fire pump controller components against metallic debris or drilling chips. Failure to do so may
cause injuries to personnel, damage the controller and subsequently void warranty.
Incoming power terminals on the controller are suitable to accept wire based on that selection with insulation not
less than 60°C. (Refer to terminal diagram for terminal sizes.)
The electrical wiring between the fire pump controller and the pump motor shall be in rigid, intermediate, or liquid
tight flexible metal conduit or Type MI cable and meet the requirements of NFPA 70 National Electrical Code or
C22.1 Canadian Electrical Code or other local codes.
The number of conductors required varies depending on the model of starter:
3-wires plus ground sized at 125% of full load current for models MPA, MFA.
Incoming Power Connections
Incoming normal power is to be connected to terminals located on the disconnecting means IS.
- For 3 phases motor: identified L1-L2 and L3.
- For single phase motor: identified L1 and L3
Motor wires shall be connected to terminals identified by:
- T1-T2 and T3 located on main contactor (1M) for models MPA,MFA.
It is the responsibility of the installer to obtain connection information on the motor and to assure that the motor is
connected as per motor manufacturer recommendations. Failure to do so may cause injuries to personnel, damage
the motor and/or the controller and subsequently void warranty on both items.
