2.4.2 Connection to the Ethernet Network
Figure 8:
Ethernet connections
The AGLAS Master is to be connected via a shielded CAT5 network cable,
with RJ45 plugs to the ETH-0 port and the hub or switch
of the Ethernet network. The cable is to be run as a 1:1 connection or Eth-1.
The usual segment length restrictions for Ethernet networks apply.
(For the location of the Ethernet connectors: refer to “Front View with Control Unit” on page 9).
2.4.3 Earth Grounding
To protect the devices against surges that could be caused by a lightning strike, each AGLAS Master is to be earth ground
separately via the earth ground screw, with minimum induction or resistance. For this an earth ground cable with a suitable cable
lug is to be fixed to the earth ground screw on the AGLAS Master (M6 screw thread). The cross-sectional area of the cable should
be at least AWG 8 (6mm
2)
with a maximum cable length of 39” (1m).
All masters ground terminals must be connected to a common earth grounded bar in the vault or substation.
(For the location of the earth ground screw: refer to “Rear View with Connections” on page 11.)
