Bus Cable Length and Wiring Details
IMPORTANT: The maximum distance between the last module
or device and the webmanager is always 60 m (196 ft), (C) + (E) , (C) + (D) + (E) or (C) + ((D) * 2) + (E), depending on the number of splitting boxes.
A splitting box does not increase the maximum distance.
NOTE: If the maximum distance needs to be increased a
repeater can increase it up to 100 m (328 ft). A repeater can increase
the distance between, for example, the webmanager and a splitting
box. The maximum distances are then calculated from the repeater instead
of the webmanager.
| Indication | Description | Max Length |
|---|---|---|
| (A) | (Optional) Cable between webmanager and any external sensor connected to COM2. | 15 m (49 ft) |
| (B) | Power supply cable. Always use a stabilized power source. The standard power supply delivers 12V/2A DC, if more than 300 modules are connected a 12V/3A DC power supply is used instead. | — |
| (C) | Maximum cable length between the webmanager and the splitting boxes. | 10 m (32 ft) |
| (D) | Maximum cable length between splitting boxes.* | 2 m (6.5 ft) |
| (E) | Maximum cable length between the splitting box and the last module in the line. | 50 m (164 ft) |
| (F) | Cable length between modules in a line. The values of (C), (D) and (E) are calculated with 40 cm (16 in). The max length will depend on the number of modules and cables used between the webmanager and splitting boxes. | 40 cm (16 in) |
| (G) | Maximum number of modules is 512. | — |
| (H) | Maximum distance from the webmanager to the last current sensor. | 10 m (32 ft) |
| (I) | Maximum distance between the dry-contacts and the last GX_R_AUX. | 50 m (164 ft) |
