Figure 30: PU Port Connections
•
For 700-series drives, the gateway can connect to the ASD via either the
PU (panel) connector as indicated in Figure 30, or via the on-board RS-485
terminals. Because both of these ports externally present a 4-wire RS-485
network, connecting them to the gateway requires jumpering the network
wires for 2-wire format (i.e. connecting SDA-RDA and SDB-RDB). When
using the on-board RS-485 terminals, connect as shown in Figure 31.
