Installing HiPath 3800 (Standalone) 
 
This section contains information on how to install the HiPath 3800 communication system. This chapter describes the standard installation procedures for the basic system. Refer to Chapter 9 "Expanding and Upgrading HiPath 3000" for information about supplementary equipment or expansions.

4.1.3.1  
Selecting the Installation Site 

Selecting a site  
The customer usually has a preferred installation site in mind.
Make sure that the customer's site meets the following guidelines:
 •   To guarantee sufficient system ventilation, allow a minimum of 50 mm clearance between the base of the cabinet and the ground and between stacked cabinets.
 •   When cabinets are stacked, the basic cabinet must always be at the bottom of the stack.
 •   Allow a minimum clearance of 10 cm both at the rear and the front of the cabinets for maintaining boards and for wiring.
 •   Do not expose the systems to direct sources of heat (for example sunlight and heaters).
 •   Do not expose the systems to extremely dusty environments.
 •   Avoid contact with chemicals.
 •   Take every precaution to prevent the formation of condensation on the system during operation. Systems covered with condensation must be dried before being used.
 •   Observe the environmental conditions specified in Section 2.11 "Environmental Conditions".
 •   Install additional primary protection.
 •   Avoid standard carpeting, as it tends to produce electrostatic charges.
 •   Ensure the availability of a power source that meets the requirements described in Section 4.1.3.1 "For U.S. only: Power plug".
 •   Ensure that a distance of at least 40 in. (101.6 cm) is left between Siemens Enterprise Communications GmbH & Co. KG equipment and other electrical equipment. The National Electrical Code (NEC) requires 36 in. (91.44 cm) of clearance in front of electrical equipment and 40 in. (101.6 cm) of clearance from other electrical service equipment.
Information on the design of the HiPath 3800 can be found in Section 2.1.4.1 "Design and Dimensions of HiPath 3800".

4.1.3.1.1  
For U.S. only: Power plug

WARNING  
Never connect a HiPath 3800 system or a combination of HiPath 3800 systems directly to a wall socket. Use a UL-listed or CSA-certified surge protector for every two cabinets.  

AC Outlet Requirements  
 •   A UL-listed or CSA-certified surge protector must be connected between the socket and the system. Two cabinets can be connected to each surge protector. Never connect a HiPath 3800 system or a combination of systems directly to a wall socket.
 •   The power source may not be more than 2.4 m (8 ft.) from the system.
 •   The power source must provide 120 V AC (single-phase, fused) power at 50-60 Hz and 20 A.
 •   A warning should be attached to the circuit breaker to prevent accidental removal of power.
 •   An independent electric circuit with an isolated ground conductor should be used.
The system must be properly grounded before startup (see description in Section 4.1.3.4 "Grounding the System").

4.1.3.4  
Grounding the System 
Ground the system as described.

4.1.3.4.1  
Not for U.S.: Grounding the System 

Grounding: Grounding options  
Implementation guidelines in accordance with IEC 60364 and IEC 60950-1 must be adhered to during installation.
Danger  
Each HiPath 3800 system cabinet and all external main distribution frames (for example, MDFU-E) must be grounded as shown in Figure 4-5 by a separate ground conductor (minimum cross-section = 2.5 mm2). Make sure that the ground conductor is securely installed and strain-relieved.  
If external factors can impact on the ground conductor and if protected installation is not possible, the ground conductor must have a minimum cross-section of 4 mm2.  
Failure to follow these instructions can result in electrical shock.  
The illustrations starting with Figure 4-6 show different grounding options.
Danger  
If your personnel are not qualified to work on the low-voltage network (230 Vac), you must hire a licensed electrician to ground the system separately using option 1b (Figure 4-7). The Section 1.6.1 "Connection to the Power Circuit" is to be adhered to.  

Note on possible ground loops  
To avoid ground loops from remotely operated devices (V.24 system peripherals), the devices should be connected to the same low-voltage network (sub-distribution board) if possible.
If the building floor plan does not permit this, you may need a line driver to isolate the external devices in the event of a malfunction.

4.1.3.4.2  
For U.S. only: Grounding the System 
Implementation guidelines in accordance with NEC (National Electrical Code), UL 60950-1 and IEC 60364 must be adhered to during installation.
A connecting cable is used for grounding the system cabinets. The system must also be grounded by a separate ground conductor. Choose a ground connection with less than 2 ohms of resistance, such as:
 •   Master ground busbar
 •   Ground field
 •   Copper ground rod
Run a separate earth ground conductor from the earth ground to the cabinet frame ground (located in the lower right corner of the backplane). The minimum cross-section required is 12 AWG.
Figure 4-8 shows the safety conductor connectors for the basic cabinet. An expansion cabinet requires a separate earth ground.
 Figure 4-8   HiPath 3800 - Earth ground connection (for U.S. only)
 
DANGER  
This wire installation must be completed by a qualified electrician and must comply with the national and local electrical codes. The Section 1.6.1 "Connection to the Power Circuit" is to be adhered to.  

Grounding the Main Distribution Frame  
Mount and ground the MDF in accordance with the manufacturer's instructions.
