4.4 Installing the Control Panel
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.
4.5 Connecting Earth Ground
4.5.1 Terminal 10
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.
4.5.2 Ground Fault Detect Enable
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.
