Equipment Grounding 
General Description 
1.5 Redundant and independent equipment grounding conductors (see Note 1) are to be 
installed between the product and the wiring system ground. 
One of the equipment’s grounding conductors shall be an insulated grounding 
conductor (see Note 2) that is not smaller in size and is equivalent in insulation material 
and thickness to the grounded and ungrounded branch circuit supply conductor, except 
that it is green with or without...

SX-ZULU SG Grounding 
Table 1-I and Table 1-2 detail the grounding cables for control and peripheral 
cabinets. Refer to Figure 14, Figure l-7, and Figure 1-8 when using the tables. 
Safety ground cables are connected to the chassis of the cabinet and units within the 
cabinet via ground studs which are located at relevant points on the equipment. 
Cables which terminate on shelf converters have sufficient length to prevent 
unnecessary cable strain when the door is opened. Care should be exercised to...

*The requirement for this cable is dependent on which configuration options are employed. 
Notes: 1. Cable length must not exceed 50 feet. 
2. This cable should be a continuous conductor which has a total resistance of less than 0.5 ohms when 
measured between its point of origin;...

SX-2000 S Grounding 
Two separate grounding paths must be provided to the SX-2000 S system. 
l Building (approved) ground 
l Electrical (safety) ground 
Figure l-9 shows the grounding arrangements for the SX-2000 S system. 
The building (approved) ground path is completed by a customer-supplied conductor 
which terminates on the Power Distribution Unit system ground terminal, located on the 
rear of the cabinet. The system ground is distributed within the cabinet to provide a-48
