Use solid or stranded wire. All wiring must meet the following specifications:
• Minimum insulating rating of 300V
• You are not allowed to solder the conductor
• Wire ferrules can be used with stranded conductors; copper ferrules
recommended
• Single wire per connection
Removable Connector Keyring
Each terminal block on each module is numbered with its corresponding pin
numbers, which match the pin numbers on its Removable Plug Connector
(RPC). Additionally, each terminal block on each module and base also
includes two keys that make sure that only its matching RPC can be plugged
into it. However, with sufficient force it is possible to defeat the keys. If the keys
are defeated, then when the RPC is later removed it is possible that the key
becomes dislodged from its pin location.
If a key is removed from its connector, it isn’t necessary to replace it as it only
serves to help match the RPC to its connector. However, the key can be readily
inserted back into its connector. When doing so, make sure that the key is
placed into the correct pin location as shown in Tabl e 5
.
