9 -  Lock down tab 

 

1.  Place the control panel over the inside back of the 

enclosure, aligning the large rectangular openings 
of the mounting skirt with the mounting hooks of 
the enclosure. Slide the control panel down so 
that it hangs on the hooks. Refer to Figure 2, Item 
2 on page 15.  

2.  Remove the tape from the #6 x 1/4-in. screw in 

the mounting tab on the control panel. The screw 
passes through the mounting tab and into the 
skirt mounting hole in the enclosure. Tighten the 
screw to secure the control panel in the 
enclosure. 

3.  Connect earth ground to the control panel before 

making any other connections. Refer to Section 
4.5 Connecting Earth Ground. 

To help prevent damage from electrostatic charges or 
other transient electrical surges, connect the system 
to earth ground at Terminal 10 before making other 
connections. Recommended earth ground references 
are a grounding rod or a cold water pipe. 

 

Caution: Do not use telephone or 
electrical ground for the earth ground 
connection. Use  
1.8 mm (14 AWG) to 1.5 mm (16 AWG) 
wire when making the connection.  

Do not connect other control panel 
terminals to earth ground. 

 

To meet UL 864 requirements, enable 
Ground Fault Detect. 

A ground fault is a circuit impedance to earth ground. 
The control panel has a ground fault detection circuit 
that, when enabled, detects ground faults on 
Terminals 1 to 9 and 11 to 32. The control panel also 
detects and annunciates ground faults on any device 
connected to it.
