equipment on page 38 for information about control. Refer to Connect the electrical
supply on page 38 for instructions on how to connect the electrical supply.
4.5.1 Ground the connections
We recommend you to install a separate ground conductor to ground the pump. Use the
braided wire that is not insulated or a separate insulated green / yellow connector with
a minimum 10 AWG (5.3 mm
2
) conductor (to comply with US and Canadian installation
codes), M5 x 10 screw and shake proof washer supplied (installed to the ground hole of
the pump) to inatall the ground conductor to the pump. The impedance between the
pump body and the earth connection point must be < 0. Ω.
4.5.2 Connect the logic interface to the TIC
If the manufacturer's TIC Turbo Instrument Controller or a TIC Turbo Controller is used to
power and control the pump, connect the pump logic interface cable into the back of
the TIC. Refer to the TIC Instruction Manual for more information.
If the TIC is to be used to control the pump, make sure that the RS485 / RS232 slide
switch is in RS232 position. Refer to Connect the serial interface to the customer control
equipment on page 41 . If the switch is in the RS485 position:
▪ the TIC will connect to the pump in parallel mode (that shows the pump type as
nEXTp)
▪ the serial connection is disabled
▪ start and stop is possible.
4.5.3 Connect the logic interface to the customer control equipment
If you operate the pump with the customer control system, use an applicable connector
mating half (not supplied) to connect the control equipment to the connector on the
logic interface cable (refer to Table: Logic interface technical data on page 27 ). Refer to
Table: Logic interface connector pins on page 28 for full details of the logic interface
connector pins when you do the electrical connections to the pump given in the sections
that follows.
You can control the pump with a hardware parallel control interface or through the
commands sent over a serial interface.
If you control the pump with the hardware parallel interface, refer to
Connect the
parallel control and monitoring on page 40 for more information. If the serial interface is
used, refer to Connection for serial control and monitoring on page 41 . The logic
interface gives the facility to work with a mixture of parallel and serial control. Refer to
Connection for mixed parallel and serial operation on page 50 .
4.5.4 Connect the electrical supply
WARNING: POWER SUPPLY
Risk of damage to equipment. A separate power supply (not included) is necessary
for the product. The power supply must be protected against a hazardous live
condition (for example, a short circuit).
