Installation
ACE969TP and ACE969FO
Multi-Protocol Interfaces
Connection
DE52078
Two-Wire RS485 Communication Ports
(S-LAN or E-LAN)
1 Connect the RS485 twisted pair (S-LAN or E-LAN) to black terminals A and B.
2 Connect the twisted pair for the distributed power supply to green terminals V+
and V-.
3 The interfaces are fitted with clamps to hold the network cable in place and to
recover shielding at the incoming and outgoing points of the network cable:
b The network cable must be stripped
b The cable shielding must be around and in contact with the clamp
b Shielding continuity of incoming and outgoing cables is ensured by the
electrical continuity of the clamps
4 An internal connection links all cable clamps to the ACE969 Interface grounding
terminals (protective and functional grounding), with the shielding of the RS485
cables is grounded as well.
5 On the ACE969TP interface, the cable clamps for the S-LAN and E-LAN
RS485 networks are grounded.
Note : The cable shielding shown at left should only be done at one point, preferably at one end
of the daisy chain.
DE52165
Fiber Optic Communication Port
(S-LAN)
CAUTION
HAZARD OF BLINDING
Never look directly into the fiber optic.
Failure to follow this instruction can cause serious injury.
The fiber optic connection can be made:
b point-to-point to an optic star system
b in a ring system (active echo)
The transmitting and receiving fiber optic fibers must have male ST type connectors.
The fiber optics screw-lock to Rx and Tx connectors.
