Installation and Connection
NOTE!
To use the analog inputs and/or outputs with signal in current, you must set
„
switch S1 and related parameters as per
information, refer to the MW500 programming manual.
To modify the digital inputs from active low to active high, check the use of
„
parameter P0271 in the MW500 programming manual.

NOTE!
Configuration to connect the RS-485:
S1.3 = ON and S1.4 = ON: terminal RS-485 ON.
„
S1.3 = OFF and S1.4 = OFF: terminal RS-485 OFF.
„
Any other combination of the switches is not allowed.
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 cables separated from the other wiring
(power, command in 110 V / 220 Vac, etc.), according to
on page 17. If those cables must cross other cables, it must be done perpendicularly,
keeping the minimum separation distance of 5 cm (1.97 in) at the crossing point.
Connect the shield according to the figure below:
