AUX-ODU-INJ-G is an optional accessory, which may be used to connect third-party DC power sources to the ODU (for example, to power the unit from solar power or wind power sources).
AUX-ODU-INJ-G should be properly assembled, mounted and grounded.
AUX-ODU-INJ-G Mounting
AUX-ODU-INJ-G can be can be installed on a pole, using hose clamps (2). Attach the grounding cable (min cross-section 2.5 mm2) to the case, using grounding bolt (3).

CAUTION
Missing or bad grounding may leave the unit vulnerable to lightning damage.
AUX-ODU-INJ-G Cable Gland Assembly
In order to ensure that the cable gland remains sealed under any environmental conditions, please, follow the assembly sequence according to procedure below:
1) Put the cable gland nut (1), the split sealing grommet (2) and the cable gland threaded coupling (3) onto the cable FTP Cat5e
2) Crimp the connector onto the cable using the crimping tool:
CAUTION
Make sure that the connector is well crimped. A loose connector can damage the device. Please note that such damage is not coveded by the warranty.
- For connection to "ETH IN" terminate the cable with the unshielded RJ-45 connector (4) according to the EIA/TIA-568B
- For connection to "ETH OUT" terminate the cable with the shielded RJ45 connector (5) according to the EIA/TIA-568B (to provide grounding circuit)
- For connection to "PWR" terminate a cable with the power connector (6).
NOTE
Allowed to use a pre-crimped cable with RJ-45 connectors.
3) Insert the connector of the pre-terminated cable into the corresponding socket until you hear a click.
4) Screw the cable gland threaded coupling (3) into the port and tighten it. Do not apply excessive force.
5) Tighten the sealing grommet (2) by the cable gland nut (1). Do not apply excessive force.

Power connector scheme is below
Follow requirements:
- Press on these catchers (1) when the cable is terminated;
- Use the round cable with diameter from 5mm to 6mm with conductor cross-section from 0.5mm to 2.5mm;
- FTP Cat5e cable may be used.
AUX-ODU-INJ-G Grounding Scheme
The grounding and lightning protection initial procedures when using AUX-ODU-INJ-G are similar to those when using regular IDU.
