Procedure 2-9
Mounting the Chassis and Installing Supplemental
Ground in a Wall Mount Installation
Note:
A supplemental ground connection is required for 3916 DC
Standard installations. The supplemental ground connection is optional for
3916 AC Standard and 3916 Dual AC Standard installations. A
supplemental ground connection is not required or available for mini
chassis systems. For systems that do not require a supplemental ground
connection see
“Mounting the Chassis (Supplemental Ground not
required) in a Wall Mount Installation” on page 2-27
for a procedure.
The following procedure explains how to mount the chassis and connect the
3916 to supplemental ground when the 3916 is installed on a wall. Standard
chassis systems must be positioned on the wall so that the air outflow and
power supply are at the bottom and the air intake is at the top.
Note:
The systems cannot be mounted with the faceplate facing up or
down.
Step
Action
1
Position the standard chassis on the wall so that the air outflow and power
supply are at the bottom and the air intake is at the top.
Note:
For a standard chassis system, when left facing mounting is required
for cable routing and faceplate access, the bracket will need to be mounted
so that the unpainted underside of the unit faces outward when installed.
2
Mark the locations of the mounting holes on the wall.
3
Set the chassis aside and install customer supplied fasteners/anchors to the
wall in the marked locations as required.
4
Reposition the chassis on the wall and use four customer supplied screws to
secure the mounting brackets and chassis to the wall.
5
Route the supplemental ground cable through the cabinet or installation site.
6
Insert the ground wire into the customer supplied ground lug. Using a ratchet
crimper, crimp the ground lug.
Note:
The ground lug should be a 2 hole lug @ 5//8 centers and with hole
size for #10 or 1/4” screw.
7
Using a Phillips screwdriver, remove the two screws on the left side of the
chassis.
8
Position the ground lug over this space and use the two screws to secure the
ground lug to the left side of the chassis.
