Pre-installation procedure (site planning)
Procedure
1.
Verify the received shipment contains the TGP and is identified with ABB6AGC106969.
2.
Refer to the required parts for installation in section 8.3 to prepare and order these items.
3.
Make sure all components meet the requirements for the electrical installation. Refer to
section 4.2.
4.
Design the local network architecture meeting the network requirements for the TGP. Re-
fer to section 4.2.
5.
Refer to the cable specifications in section 8.4 to prepare and order these items.
6.
Make sure that the cable slack for each cable is sufficient to guide the cables in the cabi-

Prepare place for installation
4.2.1
Ambient conditions
The use of the Terra Gateway Pro in dusty environments must be avoided. This can otherwise lead
to dust deposits that affect the functionality of the device, especially in systems with active cooling
(fans), which may no longer ensure sufficient cooling.
The presence of aggressive gases in the environment can also result in malfunctions. In combina-
tion with high temperature and relative humidity, aggressive gases – for example with sulfur, nitro-
gen and chlorine components trigger chemical processes that can very quickly impair or damage
electronic components. Blackened copper surfaces and cable ends in existing installations are indi-
cators of aggressive gases.
When operated in rooms with dust and condensation that can endanger functionality the Terra
gateway pro is protected on the front against the ingress of dust and moisture when installed cor-
rectly (e.g. cutout installation). The back of the device must be protected against the ingress of
dust and moisture, however, or the dust deposits must be removed at suitable intervals.
4.2.2
Mechanical requirements
The TGP is installed using two M5 screws, which are not included in delivery. The TGP offers two
different installation options (see appendix 1 for mechanical dimension). Torx screws (T20) are used
to connect the mounting bracket to the chassis.
