8) Wiring Installation
Upon installation maximum cable lengths must be adhered to, use the following table to calculate the
maximum cable lengths, taking in to account the cross section of the cables.

If the above table does not correspond to your system design the following calculations can be used for
cable length:
The cable length from the actuator to junction box should not exceed 10m,
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.
