TOSHIBA TCB-PCIN4E Output Control Board Installation Guide

TOSHIBA TCB-PCIN4E Output Control Board

Product Information

The product is an Output Control Board with the model number TCB-PCIN4E. It is compatible with SMMS-u or SHRM-A systems. The board is used for controlling and monitoring the operation of the outdoor unit.

The installation manual provides important safety precautions, which should be read before proceeding with the installation.

External View

The board has a terminal block (M3) with 4-4 mm diameter mounting holes. It also includes various accessories such asconnection cables, wire clamps, binding bands, and clamp filters of  different diameters.

Optional PCB

There are two types of optional PCBs available, type A and type B. The number of optional PCBs that can be installed depends on the model. The optional PCBs are connected to the main interface PCB using connector cables.

Wiring

The output wiring should be connected to the board using clamp filters and binding bands. If multiple optional PCBs are installed, all the connection cables should be banded together and attached with one clamp filter. The redundant connection cables should also be banded together using a binding band.

The connection cable and output wiring should be fixed using wire clips and cable straps.

Product Usage Instructions

1. Before starting the installation, make sure to turn off the power supply.
2. Install the optional PCB at the specified position inside the electrical components box.
3. Use the fixing support to secure the optional PCB in place.
4. There are four mounting holes inside the electrical components box for attaching the fixing support.
5. Connect the connector (PJ20) on the optional PCB to the connector (CN511 or CN514) on the interface PCB using the provided connector cable.
6. Tie the cable using the binding band.

For detailed information on the operation and electrical wiring, refer to the product manual.

Wiring

1. Attach the clamp filter (8) to the connection cable ( 1 or 2 ) and attach the clamp filter (10) to the output wiring as shown in the figure.
   Use binding band B (9) to fix the clamp filter (8 or 10) to the wiring.

• When more than one optional PCBs are installed, band all the connection cables and attach one clamp filter. 2. Band the redundant connection cables ((1 or 2) as shown in the figure and tie them with binding band A (7). 3. Fix the connection cable ( 1 or 2 ) and the output wiring with wire clip and cable strap as shown in the figure.

CAUTION

Output Relay (K1, K2) Contact Specifications

• Output terminals (OUTPUT1, 2) must satisfy the following electrical rating.
• When connecting a conductive load (e.g. relay coil) to loads K1 and K2, insert a surge killer CR (for an AC power supply) or a diode for preventing back electromotive force (for a DC power supply) on the bypass circuit.
