Step 4B - Bond ac ground and dc output to telecom ground electrode (if required)
Ignore this Step if the DC common bar must be connected directly to the telecom
ground electrode (see Step 4A on page
1
Connect a telecom ground link cable to the chassis of the APS as shown in the
following diagram. Use:
Wire:
Multi-strand, copper conductor, 3/0 AWG* with
green/yellow insulation
Strip length:
5/8" (16mm)
Crimp lug:
FCI-Burndy type YAV27L-TC12-FX, or
YAV27L-TC12-45, or YAV27L-TC12-90
Crimp tool:
FCI-Burndy type MY29-11
* If 3/0 AWG cable is not available, use 2/0 AWG cable and appropriate UL-Listed
Crimp Lug.
2
Tighten terminal to 18.7 - 21.9Nm (166 - 194 inch-pounds).
3
Terminate the cable at the site's telecom ground electrode directly or via the site's
telecom ground bus bar, if provided.
Telecom ground link
cable to site's
telecom ground
electrode (3/0 AWG*)

Task 4 - Connect External Input/Output Cabling (if required)
The APS is fitted with an input/output (I/O) board. This provides a number of digital inputs
and digital outputs (relays). See Input/Output Board on page
board can control and monitor external devices.
If no external devices are to be connected then ignore this task.
Step 1 - Access the I/O terminals
Remove the Input/Output cover (see the diagram on page
) and partly withdraw the
I/O board.
