STEP 2. Installing guide rails and wiring connectors Guide rails Positions of guide rails and wiring connectors are indicated in Figure 3, page 6. Centers of guide rails should be 27 HP (27 TE) apart, for example, at 1 HP (TE) and 28 HP (TE). Wiring connectors The applications platform is shipped with a solder-tail or screw-type connector for input/output wiring, a keyed solder-tail or screw-type connector for sensor wiring (Model 3500 only), and a plug-in connector for power supply wiring.
Figure 3. Positions of guide rails and wiring connectors Guide rail centers should be 27 HP (27 TE) apart; for example, 1 HP (1 TE) and 28 HP (28 TE) Install screws and connectors from front of rack. • Model 3500 has six M2.5x8 screws and three connectors. • Model 3300 has four M2.5x8 screws and two connectors. Back Keys on sensor wiring connector Front M2.
STEP 4. Connecting input and output wiring Connect input and output wiring to the appropriate terminals on the input/output wiring connector, which is the far right connector. Refer to Table 1 and to the card that is inserted into the sleeve on the top panel (shown in Figure 4). • Use 24 to 16 AWG (0,25 to 1,5 mm2) twisted-pair shielded wire. • Ground the shields at a single point only. Table 1.
