4. PUMP MODULE POWER SUPPLY
After all water and plumbing connections have been completed, a licensed, qualified electrician should connect the power
supply to the pump. It is important to follow the National Electrical Code (NEC), as well as any local codes to ensure a
safe installation.
CAUTION !
If the pump unit will be powerd by a generator at any time, a properly sized line reactor needs to be installed prior to
the pump unit to eliminate voltage spikes. If this is not done, the Variable Frequency Drive (VFD) & procesor could
be damaged and warranty may be voided.
INSURE ELECTRICAL SPECIFICATION
Establish that the circuit to be used to power the pump module is of the same electrical specification as the pump
module. The IBEX electrical specification can be found on the serial number label or from the electrical wiring
diagram adhered to the inside cover of the electrical enclosure on the pump module.
4.2.1 The circuit to the pump module must be dedicated and properly sized to carry the electrical load placed upon
it by the pump motor. Please refer to the MicroCool

Engineering Manual or electrical data plate on the
motor to determine the amperage draw of the Ibex pump module.
4.2.2 The power supply to the pump module must be hard wired directly to a fused disconnect box. If the power
supply cannot be directly wired to a disconnect box, then it should be hard wired, using a junction box, into a
suitable circuit with a disconnect box located elsewhere. This applies to either single phase or three phase
applications.
4.2.3 After verifying all of the above, power should be taken from the disconnect box/junction box to the terminal
strip located inside the electrical enclosure mounted on the pump module. We recommended that the correct
sized wiring be in conduit (preferably liquid tight); make the final connection to the high voltage terminal strip.
ELECTRICAL CONTROLS
The high voltage motor electrical supply must be connected to the pump module inside the control box. The low
voltage control wiring must also be connected inside the control box. We recommend that a LICENSED
ELECTRICIAN IS USED FOR ELECTRICAL CONNECTIONS.
ELECTRICAL CONNECTIONS/ HIGH VOLTAGE
Open front cover to connect the high voltage wiring to pump controls. Connect high voltage to TB1(terminal block
1) electrical strip in the control box. There is a conduit connector provided for connecting conduit to the side of the
control box.
