(For ambient temperatures of 25 ° C) If the above table does not correspond to your system design the following calculations can be used for cable length: Maximum permissible voltage drop in the cable: 2.5V Max. cable length = permissible voltage drop (2.5) x conductivity of copper (56) x Cable cross-sectional area (A) Max. Actuator current total (I) x2

The cable length from the actuator to junction box should not exceed 10m,
