Appendix 5-2 Notes for AC servo system

Appendix 5-2-1 General Precaution

It takes 10 minutes to discharge the bus capacitor.
When starting wiring or inspection, shut the power off and wait for more
than 15 minutes to avoid a hazard of electrical shock.

Appendix 5-2-2 Installation

MDS-R Series have been approved as the products which have been
installed in the electrical enclosure.
The minimum enclosure size is based on 150 percent of each MDS-R
Series combination. And also, design the enclosure so that the ambient
temperature in the enclosure is 55C (131F) or less, refer to the
specifications manual.

Appendix 5-2-3 Short-circuit ratings

Suitable for use in a circuit capable of delivering not more than 100 kA
rms symmetrical amperes, 500 volts maximum.

Appendix 5-2-4 Peripheral devices

To comply with UL/c-UL Standard, use the peripheral devices which
conform to the corresponding standard.
- Circuit Breaker, Fuses, Magnetic Contactor and AC Reactor

Appendix 5-2-5 Field Wiring Reference Table for Input and Output

(MDS-R Series)
Use the Tyco Electronics Corporation "Dynamic Series" connectors to
wire the input and output terminals of MDS-R Series. Crimp the pins with
the crimping tool recommended by the manufacturer.
This wire size is each unit maximum rating. The selection method is
indicated in each specification manual. (See Manual: No. BNP-C3045)
