3.2 Electrical Installation
Warning:
Electrical installation must be done by skilled personnel. Wiring must
meet all applicable codes and standards.
Refer to appropriate wiring and terminal descriptions for external connections.
Be sure that the voltage selector on the regulator PCB is in the correct position for the
voltage supplied.
Select the PCB fuse size according to the input voltage selected. The maximum
external fuse on the input is 10 A.
Note:
0VDC and PE are internally connected.
Note:
Double-check accuracy of all wiring connections before applying power to the
controller. Damage caused by improper wiring is not covered under warranty.
EMC Requirements
Connect protective ground wire to terminal marked PE. Ground wires should be as
short as possible. Connect PE, mounting plate, and cabinet to a common ground.
Use
only
shielded cable for all external connections. For analog signals, terminate
shield at controller end; for digital signals, terminate shield at both ends. For cabinet
versions, connect shield to the cabinet at the point where the cable enters, whether to
a buss bar or to the connector housing. Keep the shield as short as possible (not to
exceed 10 mm or 0.4 inches). For best results, clamp the uninsulated shield directly
to the buss bar with the strain reliefs provided.
Keep signal cables away from supply cables or any wires that conduct high current.
For best noise immunity, run signal cables close to the machine frame, mounting
plates, or other grounded structures.
