3-3 Electrical Connections

When making electrical connections to your additive feeder, ensure that you take into consideration and make arrangements for the following:

•A qualified electrician should make all electrical connections.

•Fulfill all national, state, and local safety and electrical code requirements.

•The serial tag lists voltage, phase, and amp draw information

•Line voltage must be within plus or minus ten percent (±10%) of the voltage listed on the serial tag, or damage may occur.

•Install a fused disconnect with a lockout feature in the power main leading to the additive feeder if the unit will be wired directly to a power main.

•Make sure all electrical connections are tight.

Main Power Connection

The control is shipped pre-wired and attached to the additive feeder. Standard controls are supplied with a power cord with the plug wired to the control unit, ready to plug into an appropriately grounded three-prong receptacle.

Control Relay Connection

To interlock the additive feeder operation to an injection molding machine, extruder, etc., remove jumper (J1) from the terminal block in the control enclosure and wire in the control relay signal from the processing machine. For injection applications the additive feeder will automatically operate at the specified rate while the screw is turning.(see 4-3, Injection Mode Application), for extrusion processes the additive feeder will run proportional to the speed of the extruder. (See 4-4, Extrusion Mode Application)

Please refer to the schematics enclosed in the information packet for the latest electrical drawings.
