Installation Procedure

MPC-PSF12/16

Adherence to these instructions will prevent

problems during initial installation of the MPC-PSF12/16.

The MPC-PSF12/16is a versatile modular power supply that is compatible with the MPS-12, MPC-12, and MPC-16mini-head- end systems. The difference between the three models is the wiring harness used.

System	Wiring Harness Used	Color Code
MPS-12	4 conductor harness	White
MPC-12	3 conductor harness	Blue
MPC-16	3 conductor harness	Blue

The hook-up configuration below illustrates the harness installa- tion for each model for a single module.

MPSM45

Modulator (4-pin dc plug)

White cable ties

MPS-12 Power Harness

MPCM45

Modulator (3-pin dc plug)

Blue cable ties

MPC-12 or MPC-16 Power Harness

MPS-12

1.If user prefers to retain currently installed DC power supply harness, disconnect the 12-pin connectors (4 pcs.) and the 110 volt AC power cord from the back of the MPC-PSF12/16.

2.Remove the power supply module by sliding module out from front of MPS-12 chassis.

3.If user prefers to install new DC power supply harness with replacement power supply, disconnect the harness from the mini- modules and the 110 volt AC power cord from the back of the MPC-PSF12/16. Remove the power supply module with DC har- nesses by sliding module out from front of MPS-12 chassis.

4.Insert the new MPC-PSF12/16 half-way into the chassis. CAUTION: Be sure that the PCB is properly aligned into the chassis PCB rail. Connect the green ground wire to the top of the module with one of the cover screws.

5.Connect the appropriate harness’ 12-pin dc connector (4 pieces) to the 12-pin jacks located on the power supply.

6.Connect the 4-pin connector to the power jack located on the back of the modulator,

7.Connect the power cord. Verify that the power lights on the front of the modulator are lit.

2.Remove the power supply module by sliding module out from front of MPC-12 chassis.

3.If user prefers to install new DC power supply harness with replacement power supply, disconnect the harness from the mini- modules and the 110 volt AC power cord from the back of the MPC-PSF12/16.

4.Remove the power supply module with DC harnesses by slid- ing module out from front of MPC-12 chassis.

5.Insert new MPC-PSF12/16 module with harness into chassis slot previously occupied by removed unit. CAUTION: Be sure that the PCB is inserted into the PCB slide guides. Connect power cord to MPC-PSF12/16.

6.Connect the appropriate harness’ 12-pin dc connector (4 pieces) to the 12-pin jacks located on the power supply.

7.Connect the 3-pin connector to the power jack located on the back of the modulator,

8.Connect the power cord. Verify that the power lights on the front of the modulator are lit.

MPC-16

1.Disconnect the 12-pin connectors (6 pcs.) and the 110 volt AC power cord from the back of the MPC-PSF12/16.

2.Remove the power supply module by sliding module out from back of MPC-16 chassis.

3.Insert new MPC-PSF12/16 module into chassis slot previ- ously occupied by removed unit. CAUTION: Be sure that the PCB is inserted into the PCB slide guides.

4.Connect the appropriate harness’ 12-pin dc connector (4 pieces) to the 12-pin jacks located on the power supply.

5.Connect the 3-pin connector to the power jack located on the back of the modulator,

6.Connect the power cord. Verify that the power lights on the front of the modulator are lit.
