10.2.2 Precautions

∗1. Recommended surge absorber model: LT-C32G801WS (Soshin Electric Co., Ltd.)
∗2. For more information on this noise filter, refer to 5.4 Noise Filter.
∗3. For more information on this AC reactor, refer to 5.2 AC Reactor.
∗4. Install the following surge absorber on the power line between the single-phase 200 V power supply and the 24 VDC
power supply.
Surge absorber model: LT-C12G801WS (Soshin Electric Co., Ltd.)
∗5. Install the following noise filter on the power line between the single-phase 200 V power supply and the 24 VDC
power supply.
Noise filter model: HF2005A-UP (Soshin Electric Co., Ltd.)
∗6. Use a 24-VDC control power supply with double insulation against primary or reinforced insulation.

For details, refer to diagrams in 10.2.1 EMC Installation Conditions.
(3) Fixing the Cable
Fix and ground the cable shield using a piece of conductive metal.
• Example of Cable Clamp
(4) Shield Box
A shield box, which is a closed metallic enclosure, is effective as reinforced shielding against electromagnetic
interference (EMI) from SERVOPACKs. The structure of the box should allow the main body, door, and cool-
ing unit to be attached to the ground. The box opening should be as small as possible.
Note: Do not connect the analog monitor cable to the SERVOPACK during operations.
Connect them only when the machinery is stopped during maintenance.
