Startup and Operation of the TwisTorr 305-ICQ & 305-IC SF
To turn on the TwisTorr 305-ICQ & 305-IC SF via the on board controllers, supply
the pump with the proper supply voltage and then act on the "START"and
"INTERLOCK" signals. Once these signals are recognized the controller will start the
pump.
WARNING
Never connect the user cable to the DB15 connector on the IC system or
disconnect it from said DB15 connector with the user cable powered.
Before carrying out any operation to connect to or disconnect from the DB15
connector on the IC system, you must first make sure that the user cable is
not powered (power unit must be switched off).
When disconnecting after switching off the IC system, wait until all the LEDs
are switched off before disconnecting the user cable from the system.
If this warning is not respected the IC system, or devices connected to it,
could be damaged.
The user cable can be disconnected from the IC system while the user cable
powered exclusively in the case of an emergency stop.

4 The TwisTorr 305-ICQ & 305-IC SF is provided with a DB15 mating connector,
not pre-wired. This DB15 mating connector is suitable to withstand to the
current level needed to supply the controller and it is fully compatible with the
DB15 connector which is mounted on the control unit. It can be used, after
properly wiring, both to connect the TwisTorr 305-ICQ & 305-IC SF to the
supply source as well as to the accessory parts (cooling fan, vent valves) and
