Armstrong Emech G12 User Manual

3.2.2 Power Supply Wire Specification
Consider the minimum cross sectional area and length of the supply cable such that the voltage drop across the total
cable length remains within the permissible voltage tolerance of the actuator. For example when using a 0.75mm
2
cable,
the voltage drop will be a 1.2V at 3A and 10m length, which is 5% of the 24V supply. Use the table 3.1 below as a guide to
determine cable size and maximum length.
Table 3.1 Cable length (depending on cable area and actuator model)
3.2.3 Wiring of Actuator mA Loop Receiver
To comply with EMC (Electro Magnetic Compatibility) standards, the wiring must be placed in the conduit (must be
connected to earth ground) and shielded twisted pair cable (0.25mm
2
) should be used (see Figure 3.3 below).
