charger and replacing with a new control board.
•  Part  numbers: TCB-MEXXXX, TCB-RDXXXX, 

TCB-MSXXXX or TCB-MSXXXXPAE

Note:

 

This document is part of a series of Service Instructions 

to help qualifi ed personnel replace components that have 

failed or have been damaged.

2.0 Installation 

Preparation

Before removing or replacing the control board, read this 

entire document and follow all instructions.

2.1 Safety 

Precautions

Follow all electrical safety precautions and the ESD 

prevention guidelines below, and in the 

Electrical Safety 

Precautions and Electrostatic Discharge Prevention: 

Service Instructions: 64-1000

.

Warning:

 Hazardous voltages are present within 

the inverter when power is applied. Do not remove 

the inverter’s top cover without 

fi

 rst turning off 

and disconnecting all AC and DC power to the 

inverter. Always replace the top cover before 

reconnecting power.

Warning:

 The capacitors inside the inverter 

store electric energy even after all AC and DC 

power is removed. After disconnecting all AC 

and DC power to the inverter, wait 5 minutes for 

the energy in the capacitors to dissipate before 

working on the unit.

Caution:

 Observe all ESD safety precautions 

when working with the control and FET boards, 

and within the inverter. Failure to follow ESD 

safety precautions could result in damage to 

internal components and the inverter.

2.2 Included 

Materials

Before dismantling the inverter, inspect the new control 

board to ensure there is no obvious physical damage. Look 

at the Model ID label on the new control board (see Figure 

1 or 2, Item A)

*

 and verify that the model number on this 

label corresponds to the model number of the inverter that 

is being repaired. Contact Sensata if any item appears to 

be damaged, missing or incorrect.

* - The Model ID label for each inverter/charger may 

appear anywhere on top of the board’s RJ connectors.

Note:

 

All removed items must be returned if repair is for 

warranty consideration. Save the packing material and 

shipping container to use when returning the removed items.

2.3 

Required Tools and Equipment

Before disassembling the inverter, ensure you have the 

following tools and equipment to remove and replace the 

control board:

•  T15 Torx head screwdriver (

6” shaft required) 

– for #6-32 screws

MS/MS-PAE Series Inverter/Chargers also require:

•  T25 Torx head screwdriver – for #10-32 screws
•  7/16” socket, socket wrench and 

6” extension 

– for ¼-20 bolts

•  Torque wrench (130 in-lbs torque required) 

– for ¼-20 bolts with 7/16” head

• Pliers 

(

1” jaw opening required)
