Unpacking And Inspection; Mounting Procedure - ADC Digivance User Manual

The following materials are required in order to complete the procedures in this section:
• Wall-mount fasteners (wall-mount applications only)
• #22 AWG (0.40 mm) category 3 or 5 cable (for external alarm connections)
• #18 AWG (1.00 mm) insulated stranded copper wire (for chassis grounding wire)
• Ring terminal for #18 wire (for chassis ground wire connection)
• High performance, flexible, low loss 50-ohm coaxial cable
• N-type male connectors
• Wire ties

2.2 Unpacking and Inspection

This sub-section provides instructions for opening the shipping boxes, verifying that all parts
have been received, and verifying that no shipping damage has occurred. Use the following
procedure to unpack and inspect the RIU:
1. Open the shipping carton and carefully unpack the RIU from the protective packing
material.
2. Check the RIU for broken or missing parts. If there are any damages, contact ADC (see
Section 5 at the end of this manual) for an RMA (Return Material Authorization) and to
reorder if replacement is required.

2.3 Mounting Procedure

The RIU may be either rack-mounted or wall-mounted. Of the procedures that follow, use
whichever procedure is appropriate for the installation.
2.3.1 Rack-Mount Installation
The RIU may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. Both
US standard and metric machine screws are included for rack mounting the RIU. When
loading the RIU in a rack, make sure the mechanical loading of the rack is even to avoid a
hazardous condition such as a severely unbalanced rack. The rack should safely support the
combined weight of all the equipment it holds. In addition, the maximum recommended
ambient temperature for the RIU is 50º C (122º F). Allow sufficient air circulation or space
between units when the RIU is installed in a multi-unit rack assembly because the operating
ambient temperature of the rack environment might be greater than room ambient.
Warning: Wet conditions increase the potential for receiving an electrical shock when
installing or using electrically-powered equipment. To prevent electrical shock, never install
or use electrical equipment in a wet location or during a lightning storm.
Use the following procedure to install the RIU in the equipment rack:
1. The RIU is shipped with the mounting brackets installed for 19-inch rack installations. If
mounting the RIU in a 19-inch rack, proceed to step 4. If mounting the RIU in a 23-inch
rack, proceed to step 2.
