ST-3050D SUB. PUMP/CTRL. BOX — INSTALLATION (MCP102/104)

DANGER:

Remember this control box contains hazardous voltages. Disconnect all sources of power before installing or servicing. There exists the possibility of electrocution, electric shock or burn, which can cause severe bodily harm or even death!

Remember the MCP102 Control Box is to be used only for 230 VAC 3-phase applications and the MCP 104 Control Box is for 460 VAC 3-phase applications. Neither control box has float switch capability.

It is recommended that the power being supplied to the control box ALWAYS be connected to a circuit breaker or a quick disconnect switch.This safety feature allows for quick removal of power from the control box in the event of an emergency.

4.Connect the other end of the 3-phase input power cord to the voltage source. Remember to provide a means of disconnecting the power from the control box (circuit breaker or quick disconnect switch). Also make sure to provide a good earth ground to the control box.

POWER CORD REQUIREMENTS

When routing the three phase power via a power cord to the control box,ALWAYS use the correct wire size.Please reference Table 3 (Cord Length/Wire Size) to determine the correct wire size. Incorrect wire size can adversely affect the performance of the pump.

CONTROL BOX MOUNTING

Mountthecontrolboxinanuprightverticalposition.Makesure the control box is securely fastened to a flat surface, that is free of dust, dirt, moisture or any elements that may contaminate or erode the electronic components of the control box.

3-PHASE POWER CORD (INPUTTO BOX) INSTALLATION

1.The three phase input power cord should have four wires. Each wire is color coded. The colors are RED, WHITE, BLACK and GREEN.

2.Remove the 3-phase AC input connector housing from the control box, then route the three phase input power cable through the cable gland on the control box. Attach the wires to the terminal block on the electronic overload unit inside the control box as indicated by Table5andFigure15.

3.Tighten the connector housing to ensure a tight fit between the power cord and the connector body. This will prevent the cable from pulling out of the terminal block and also prevent moisture from entering the control box.

3-PHASE POWER INSTALLATION (OUTPUTTO PUMP)

1.The three phase output power cord should have four wires. Each wire is color coded. The colors are RED, WHITE, BLACK and GREEN.

2.Remove the 3-phase AC output power connector housing on the control box, then route the three phase output power cable through the cable gland on the control box. Attach the wires to the AC terminal blocks on the electronic overload unit as indicated by Table 6 and Figure 15.
