2.4 Grounding
The Output Terminal can be grounded by the following two methods. One of or
both of the methods can be employed to ground the Output Terminal. However, we
recommend the method in which power connection cables are employed.
1. Use the supplied power connection cables to connect the Output Termi-
nal to the PCR-LA AC power supplies. This enables grounding to be
provided for the Output Terminal. For the cable connection method,
“2.5.2 Connection of Power Connection Cables”.
Connecting a power connection cable to the terminals marked “G” provides
grounding for the Output Terminal.
2. Connect the protective conductor terminal of the Output Terminal
to an electrical ground (safety ground) directly.
• Failure to ground the Output Terminal may cause electric shock.
• There is a possibility of physical injury or death. Be sure to provide ground-
ing.
• Connect the ground terminal to an electrical ground (safety ground).
For grounding of the PCR-LA AC power supplies, see the PCR-LA AC Power Sup-
ply Operation Manual.
2.5 Connections for a Single-phase/
Single-phase, Three-wire Switching System
Connecting cables between the Output Terminal and the two PCR-LA AC power
supplies completes the system connections. The main cabling work consists of the
following
fi ve items:
1. PCR-LA power supplies’ input power
2. Power connection cables (to the outputs of the PCR-LA power supplies)
3. Signal connection cables
4. Parallel Operation Driver
5. Single-phase, Three-wire Output Driver
Always use the cables provided with the expansion kit.
• The Output Terminal has no input power cables. Completing the system connec-
tions allows power to be supplied to the Output Terminal.
