4.2.3 Selecting the Installation Site

Selecting a Site

Determine the installation site ahead of time in coordination with the customer. Be sure to observe the following guidelines when selecting the site:

Do not expose the systems to direct sources of heat (such as sunlight or heaters).
Do not expose the systems to extremely dusty environments such as home workshops.
Avoid contact with chemicals, including fuels such as gasoline and household cleaners such as bleach.
Take every precaution to prevent the formation of condensation on the system during operation. If condensation forms on the system, make sure the system has time to dry completely before starting it up.
Observe the environmental conditions specified in Section 2.10.4.

For U.S. Only

Ensure that the installation site is in the immediate vicinity of an electrical outlet
Allow space for a main distribution frame or other additional equipment
Install lightning and surge arrester equipment
Avoid standard carpeting, as it tends to produce electrostatic charges
Ensure that Siemens equipment is 40 in. (101.6 cm) from 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.
Ensure that the equipment room for the system provides adequate space for installation and maintenance activities, including removing and replacing the cover. See Figure 4-40 on page 4-72 for space requirements on the sides of the system. We recommend using a plywood backboard at least 0.5 in. (127 mm) thick and measuring at least 4 ft. (122 cm) by 4 ft. (122 cm).

OfficeCom and OfficePoint Space Requirements (for U.S. Only)

Figure 4-40 OfficeCom and OfficePoint Space Requirements (for U.S. Only)

For U.S. only: The system measures 18 by 17.7 inches (460 x 450 mm). It requires 18 in. (460 mm) of clearance on the left, and at least 8 in. (203 mm) of clearance on the top and right. Allow 20 in. (508 mm) of clearance on the bottom (for cords). Observe also the NEC requirements on page 4-71.

AC Power Outlet Requirements (for U.S. Only)

Must not be located more than 6 feet (2 m) from the system
Must provide fused 120 Vac (single-phase) power at 60 Hz
Should be on a dedicated circuit with an isolated ground

4.2.5 Mounting the OfficeCom Main Distribution Frame Unit (Not for U.S.)

Introduction

The main distribution frame unit (MDFU) (see Figure 4-41 on page 4-75) is the main distribution frame used.

Installation Notes

The main distribution frame unit (MDFU) should be mounted at eye level close to the system (note the connecting cable length). Attach the unit to the wall as described in the instructions shipped with it. A bag attached to the cover contains a drill template as well as screws and wall anchors for attaching the unit to the wall.

The MDFU must be grounded. Refer to Section 4.2.7 for an explanation of the procedure.

Procedure for Mounting the MDFU on the Wall

4.2.7 Grounding the External Main Distribution Frame (Not for U.S.)

 
Because of their protection class, the OfficeCom and OfficePoint systems do not have to be grounded.  

Grounding the System (for U.S. and Canada Only)

The system power cord on the OfficeCom and OfficePoint system is grounded, but the systems also require an earth ground, as do all digital switching systems. The earth ground must meet the requirements of the U.S. National Electrical Code or Canadian Electrical Code. The earth ground must be connected between the lug provided on the OfficeCom or OfficePoint rear panel and the electrical service panel that supplies the OfficeCom or OfficePoint with power, using wire no smaller than 14 AWG.

External Main Distribution Frame

For U.S. Only

The customer supplies a main distribution frame (MDF) to complete the communications system. Mount and ground the MDF in accordance with the manufacturer's instructions.

Not for U.S.

Hicom 150 E OfficeCom: Shipments of Release 2.0 and later always include an MDFU and two grounding cables (Germany only). Use one of the cables to ground the MDFU. It is not necessary to ground the connection between the MDFU and OfficeCom (see Figure 4-44).
Hicom 150 E OfficePoint: This system type does not require an external main distribution frame. The connecting cables to the peripherals are attached directly to the boards and routed to the outside via a cable duct inside the housing.
 
Danger 
An external main distribution frame which requires grounding (if the existing ground connection is marked " ") must be grounded by a separate ground wire (minimum cross section= 2.5 mm2).  
Failure to observe this requirement may cause irreversible damage to the system.  

Refer to Figure 4-44 on page 4-79 when replacing a customer system using the existing external main distribution frame.

Route 16 TW to the MDFU via SU_X8 and 8 TW via SU_X9 (see Figure 4-45), using a standard cable (with 16 TW) for each connection. Connect both cables (1 CABLU with SU connectors labeled 8 and 9) to the same jumper strip (25 TW).  
Slot with any other peripheral board 
Without an external main distribution frame (MDFU):
You can attach cables for the peripheral boards directly to the boards (see Figure 4-47 on page 4-83 for the slip-on connectors) and route them to the MDFU through the cable duct inside the housing.
With an external main distribution frame (MDFU):
Use CABLU S30269-Z41-A30 (Figure 4-46 on page 4-82) to connect the peripheral boards to the customer's line network. As shown in Figure 4-47 on page 4-83, you can connect the eight-pin slip-on connectors to the boards directly. The line network connects directly to the jumper strip.

Figure 4-46 Layout of CABLU S30269-Z41-A30 ( 3 m long)

Hicom 150 E OfficePoint (Not for U.S.)

The integrated distribution frame of the OfficePoint system allows you to connect the cable network to the strunk and the stations using screw connections on slip-on connectors that can be easily removed for easy system connection and disconnection.

The peripheral boards and optional boards contain a distribution frame component in the form of edge connectors on the boards; the slip-on connectors for these edge connectors are supplied with the boards. You insert the wires into the screw connections on the slip-on connectors, tighten, and then slide the slip-on connectors onto the board edge connectors.

Figure 4-47 Integrated Distribution Frame-Slip-on Connector Screw Connections

If you have an external main distribution frame (MDFU), use CABLU S30269-Z41-A30 (Figure 4-46 on page 4-82) to connect the peripheral boards to the customer's line network. As shown in Figure 4-47 on page 4-83, you can connect the 8-pin slip-on connectors directly to the boards. The line network connects to the jumper strip.

4.2.10 Connecting the Cabling (For U.S. Only)

If the boards are not already connected to the appropriate cables leaving the system, you need to connect them.

The TST1 Module (OfficeCom) connects to a customer-supplied channel service unit (CSU) using the supplied cable. The CSU provides the required secondary protection.
Each port on the STLS4 Module connects to an S0 bus using the supplied, silver-satin connector cord and a surface-mounted RJ45X jack (a biscuit block). The surface-mounted RJ45X jack is not supplied.
The signals must be reversed in the RJ45X jack; see Figure 3-41 on page 3-112.
The board in Slot 10 of OfficeCom connects using a special cable from the backplane to the main distribution frame (MDF).
The remaining peripheral boards and options connect to a customer-supplied main distribution frame (MDF) or similar equipment using the supplied MDF cables (octopus cables terminated in Amphenol connectors). You select the output pattern on the Amphenol connector by which slip-on connector you use on each board edge connector.
Note that the MDF cables reverse the order of the signals from the boards, so that R/T at the board interface becomes T/R at the Amphenol connector.

Refer to the Installation Guide, OfficeCom and OfficePoint, for Hicom 150 E (G281-0582-00) for connection details.
