3.1 Caution for Wiring
1) Do not lay signal cable near to either high voltage power cabling or cabinet housing along
the same trunking duct. Effects of noise or surge induction may occur. Keep signal cables of
more than 100 mm (3.94") from these power cables.
2) Ground the shield wire or the shield of a cable at one point on the module. Do not, however,
ground at the same point as high voltage lines.
3) Cut off all phases of power source before installation or performing wiring work in order to
avoid electric shock or damage to the product.
4) Replace the provided terminal cover before supplying power and operating the unit after
installation or wiring work, in order to avoid electric shock.
5) To connect the 32DP-IF to a Profibus-DP network should be used only the Profibus
connectors and shielded twisted-pair cable complying with EN50170.
6) The power supply of the extension units/blocks and the special function units/blocks should
be starting-up at the same time or earlier than it with 32DP-IF.
7) DO NOT use “
●
” terminal in 32DP-IF.
8) “24+” and “24-” terminal are not reversible.
If “24+” and “24-” terminal are reversed, the units/block may be serious damaged.
9) The terminal tightening torque is 0.5 to 0.8 N•m. Tighten securely to avoid malfunction.
