Wiring the Power Supply

Overview

To distribute current for the 24 Vdc I/O power segment(s) and TM5 power bus according to the power distribution description, the following modules are connected to an external source:

Interface Power Distribution Module (IPDM)
Receiver module (TM5SBER2)
Power Distribution Module (PDM) TM5SPS1•
Power Distribution Module (PDM) TM5SPS2•

Source power for these can come from one or more supplies. Your requirements are dictated by:

voltage and current needs
isolation requirements

DANGER
	HAZARD OF ELECTRIC SHOCK, EXPLOSION, OVERHEATING AND FIRE Do not connect the modules directly to line voltage. Use only isolating PELV systems according to IEC 61140 to supply power to the modules. Connect the 0 Vdc of the external power supplies to FE (Functional Earth/ground). Failure to follow these instructions will result in death or serious injury.

Wiring the Interface Power Distribution Module (TM5SPS3)

The IPDM (TM5SPS3) is the first connection of the distributed configuration to the external 24 Vdc power supplies. Power is supplied by two external isolated power supplies.

There are two power connections to be made to the IPDM (IPDM TM5SPS3) from your source power supplies:

Connections	2 Power Supplies
24 Vdc Main power that generates power for TM5 power bus	PS1
24 Vdc I/O power segment	PS2

(2) External fuse, Type T slow-blow, 1 A, 250 V

(3) External fuse, Type T slow-blow, 10 A maximum, 250 V

PS1/PS2 External isolated power supply 24 Vdc

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system to meet the EMC requirements.

DANGER
	HAZARD OF ELECTRIC SHOCK, EXPLOSION, OVERHEATING AND FIRE Do not connect the modules directly to line voltage. Use only isolating PELV systems according to IEC 61140 to supply power to the modules. Connect the 0 Vdc of the external power supplies to FE (Functional Earth/ground). Failure to follow these instructions will result in death or serious injury.

Wiring the Receiver Module (TM5SBER2)

The receiver module (TM5SBER2) is the first connection of the remote configuration to the external 24 Vdc power supplies. Power is supplied by two external isolated power supplies.

There are two power connections to be made to the receiver module (TM5SBER2) from your source power supplies:

Connections	2 Power Supplies
24 Vdc Main power that generates power for TM5 power bus	PS1
24 Vdc I/O power segment	PS2

(2) External fuse, Type T slow-blow, 1 A, 250 V

(3) External fuse, Type T slow-blow, 10 A maximum, 250 V

PS1/PS2 External isolated power supply 24 Vdc

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system to meet the EMC requirements.

DANGER
	HAZARD OF ELECTRIC SHOCK, EXPLOSION, OVERHEATING AND FIRE Do not connect the modules directly to line voltage. Use only isolating PELV systems according to IEC 61140 to supply power to the modules. Connect the 0 Vdc of the external power supplies to FE (Functional Earth/ground). Failure to follow these instructions will result in death or serious injury.

Wiring the Power Distribution Module TM5SPS1•

The TM5SPS1• (PDM) divides the 24 Vdc I/O power segment into several separated 24 Vdc I/O power segments. Each separated 24 Vdc I/O power segment is supplied by one external isolated power supply depending on current needs and capabilities.

There is one power connection to be made to each TM5SPS1• (PDM) from your source power supplies:

Segment Begin	Connection	Power Supplies
IPDM for the distributed configuration	24 Vdc Main power that generates power for TM5 power bus	PS1
IPDM for the distributed configuration	24 Vdc I/O power segment 1	PS2
First PDM (from left to right) of the configuration	24 Vdc I/O power segment 2	PS3
Second PDM (from left to right) of the configuration	24 Vdc I/O power segment 3	PS4
...	...	...

The following figure shows the wiring to supply the 24 Vdc I/O power segments:

1 External fuse, Type T slow-blow, 1 A, 250 V

2 External fuse, Type T slow-blow, 10 A, 250 V

3 External fuse, Type T slow-blow, 10 A maximum, 250 V

4 Approved emergency stop device

PS1/PS2/PS3/PS4 External isolated power supply 24 Vdc

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system to meet the EMC requirements.

DANGER
	HAZARD OF ELECTRIC SHOCK, EXPLOSION, OVERHEATING AND FIRE Do not connect the modules directly to line voltage. Use only isolating PELV systems according to IEC 61140 to supply power to the modules. Connect the 0 Vdc of the external power supplies to FE (Functional Earth/ground). Failure to follow these instructions will result in death or serious injury.

NOTE: The requirements for the power supply are different for the input and the output slices. An emergency stop is generally used with the power supply providing power for output slices.

Wiring the Power Distribution Module TM5SPS2•

The TM5SPS2• (PDM) divides the 24 Vdc I/O power segment into several separated 24 Vdc I/O power segments and reinforces the TM5 power bus.

Selecting a 24 Vdc power supply should be based on current needs and capabilities.

Each separated 24 Vdc I/O power segment is supplied by one external isolated power supply depending on current needs and capabilities.

There are two power connections to be made to each TM5SPS2• (PDM) from your source power supplies:

Segment Begin	Connection	Power Supplies
IPDM for the distributed configuration	24 Vdc Main power that generates power for TM5 power bus	PS1
IPDM for the distributed configuration	24 Vdc I/O power segment 1	PS2
First PDM (from left to right) of the configuration	24 Vdc Main power that generates power to reinforce the TM5 power bus	PS1
First PDM (from left to right) of the configuration	24 Vdc I/O power segment 2	PS3
Second PDM (from left to right) of the configuration	24 Vdc Main power that generates power to reinforce the TM5 power bus	PS1
Second PDM (from left to right) of the configuration	24 Vdc I/O power segment 3	PS4
...	...	...

In the following example, the PS1 is connected to the Main power. In this case the 2 TM5SPS2• PDMs are connected to PS1 to supply the TM5 power bus:

(1) External fuse, Type T slow-blow, 1 A, 250 V

(2) External fuse, Type T slow-blow, 10 A, 250 V

(3) External fuse, Type T slow-blow, 1 A, 250 V

(4) External fuse, Type T slow-blow, 10 A maximum, 250 V

(5) Approved emergency stop device

PS1/PS2/PS3/PS4 External isolated power supply 24 Vdc

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system to meet the EMC requirements.

DANGER
	HAZARD OF ELECTRIC SHOCK, EXPLOSION, OVERHEATING AND FIRE Do not connect the modules directly to line voltage. Use only isolating PELV systems according to IEC 61140 to supply power to the modules. Connect the 0 Vdc of the external power supplies to FE (Functional Earth/ground). Failure to follow these instructions will result in death or serious injury.

NOTE: The requirements for the power supply are different for the input and the output slices. An emergency stop is generally used with the power supply providing power for output slices.
