Cable Separation Distance - WEG CFW501 Serie Manual Del Usuario

Installation and Connection
For the correct connection of the control, use:
1. Gauge of the cables: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
2. Maximum torque: 0.5 N.m (4.50 lbf.in).
3. Wiring of the plug-in module connector with shielded cable and separated from the
other wiring (power, command in 110 V / 220 Vac, etc), according to item
Separation Distance. If those cables must cross other cables, it must be done in
perpendicularly among them, keeping the minimum separation distance of 5 cm at
the crossing point.
Connect the shield according to the figure below:
4. Relays, contactors, solenoids or coils of electromechanical brake installed close
to the inverters may occasionally generate interference in the control circuitry. To
eliminate this effect, RC suppressors (with AC power supply) or freewheel diodes
(with DC power supply) must be connected in parallel to the coils of these devices.
5. When using the external HMI (refer to section
connects to the inverter must be separated from the other cables in the installation,
keeping a minimum distance of 10 cm.
6. When using analog reference (AI1) and the frequency oscillates (problem of
electromagnetic interference), interconnect the GND of the connector of the plug-in
module to the inverter grounding connection.
