7/50D Plus or 7/50D Controller Chapter 3: Installation 28
Connecting Vacuum Receivers to the Network
Make sure that all previous installation steps have been done first before starting this task.
To connect a vacuum receiver to the network:
1. Attach one connector of the yellow patch cord to the terminal on the vacuum receiver
terminal box. Tighten the cord grip ring until snug.
2. Attach the other connector to the upper left terminal of the ArmorBlock. Tighten the
cord grip ring until snug.
Note: Retain the terminal caps from the ArmorBlock. They may be used
later.
*** The installation steps listed above also apply to the 7/50D 4-connector
ArmorBlock.
Note the following illustrations for 4 and 8-connector ArmorBlocks:

3. Dress the excess patch cord cable with cable ties so it does not interfere with
operation and gives a pleasing appearance.
