DHS-E Installation
Installation Overview
1. Plan the installation, including the Key Service Unit (KSU) and main distribution frame 
(MDF) location, station locations, cable runs, ground location, and optional 
equipment.
2. Mount the Backboard, and sketch placement of all components.
3. Mount the KSU on the MDF backboard. Use the provided mounting template to aid in 
spacing the mounting screws.
4. Install optional 3 x 8 Modules inside the KSU as required.
5. Attach the punch-down...

General Site Considerations
The first step of DHS-E  installation is to locate an acceptable site for the common 
equipment (KSUs, boards, etc.). When locating a mounting site for the KSUs, the 
following points must be considered:
†KSUs are designed for wall mounting and should not be mounted directly to a 
masonry or plasterboard wall. It is recommended that a 1/2 in. plywood backboard 
be firmly mounted to the wall, and the KSU and MDF be mounted to the backboard.
†The location...

3-16DHS-E Installation
†Six conductor modular jack assemblies for all station instruments (recommended).
†Standard punch-down terminal block(s), 66M1-50 type, as required.
†Industry-standard, 25-pair cable(s) with a 50-pin male amphenol/AMP type 
connector for connection from each equipped 3 x 8 module to the MDF.
†AC voltage surge/spike protector.
Standard telephone hand tools and mounting hardware for the KSU, MDF backboard, 
punch-down terminal block(s), modular jack assemblies for CO lines, etc.
Some...

DHS-E Installation3-17
†Check that the type and quantity of boards received is correct. DO NOT unpack the 
individual boards at this time.
†Verify optional equipment is received and is in good condition.
†Verify that a Power Line Surge Protector is on-site.
DHS-E Installation
1. Backboard MDF Installation
A wooden backboard is recommended for all installations and must be installed when 
the location has masonry or plasterboard walls. A 1/2 in. plywood material is sufficient for 
most installations.

3-18DHS-E Installation
†Clamp voltage transients at 300V within 5 nsec. when exposed to wave-forms as 
described in the ANSI/IEEE Standard C62.41-1980 (IEEE 587).
†Reduce RFI/EMI noise by at least 20 dB at frequencies between 5 kHz and 30 MHz.
3. Battery Backup - System
External batteries may be connected to the KSU via the optional Starplus VC61101 
Battery Charging Unit (BCU). This unit may be equipped with batteries sized to meet the 
particular customer requirements. The approximate time, in back-up...
