sources. In addition the cabinet grounding system helps to prevent electronic noise
from entering or radiating from the cabinet.
Before applying power to the CR, the enclosure must be connected to an earth
ground. A grounding connector is provided at the base of the cabinet for this purpose
(see Figure 3-14). This connector is capable of terminating 3 2-AWG grounding
wires. In most areas two 8-foot grounding rods are sufficient. In areas of high
lightning activity or low ground conductivity, additional grounding rods or a
grounding ring should be used to increase the effectiveness of the grounding system.
You must verify that the connections to the grounding rods are in accordance with
NEC, UL, and any local safety codes that apply. The resistance of these grounding
connections must be no more than 25 Ohms.

Inspecting and replacing the door gasket
The enclosure is equipped with a gasket that is located on a flange surrounding the
opening for the door. If this gasket is damaged, excessive moisture may enter the
cabinet and damage the Stinger Compact Remote components.
Examine the gasket for any cuts, cracks, tears, or deformations. If any of these
conditions are observed, the gasket must be replaced to insure a proper seal around
the door.
Note
The gasket is manufactured with two small round holes located on either side
of the gasket glue joint near the center of the bottom horizontal flange. These are
gasket vent holes, and do not indicate that replacement of the gasket is required.
Use the following procedure to replace the door gasket.
1
Order a factory prepared replacement door gasket (comcode 408925634), and
have it available for installation.
2
Remove the old gasket material from the door flange by pulling it away from the
flange. To do this, pull one portion of the gasket away from the flange (i.e. one
corner), and work around the door opening until the entire gasket is removed.
3
Remove as much residual caulking material as possible from the perimeter of the
door flange.
4
Position the replacement gasket so that the vent holes and the gasket glue joint
are located in the center of the bottom horizontal door flange (see Figure 3-15).
