Pre-Installation Checklist
5. PRE-INSTALLATION CHECKLIST
5.1 To make installation easier, use the following checklist when preparing to install the
system. (Hardware specifications are included in the SPECIFICATIONS section.)
A. ESTABLISH SUITABLE ENVIRONMENTAL CONDITIONS FOR THE SYSTEM
• Locate the equipment chassis within 5 feet (1.5 meters) of an isolated, dedicated, 105-
125VAC, 57-63 Hz, 15A, single-phase commercial power source.
NOTE: This must be an isolated, dedicated AC circuit for proper operation. All three
wires (power, neutral, and ground) must be run separately from the outlet to the breaker
panel without being bonded to any other wire or circuit. DO NOT plug any other equip-
ment into this outlet. To maintain the protection provided by the isolated, dedicated cir-
cuit, the length of the AC power cord limits the distance between the power supply and
the outlet; DO NOT use an extension cord. DO NOT defeat (or leave floating) the
ground wire in the AC power cord. Also, to protect the system from AC voltage surges,
a surge/spike protector is recommended (see page 2-24 for specifications).
• Select the chassis location to minimize cable run length. Station instruments connected
to the system must not exceed the limits (using 24AWG, 24 gauge thickness or larger --
smaller number gauge = larger thickness) listed in the table on page 3-69. The resis-
tance values (in ohms) are loop measurements; the distance values (in feet/meters) are
the maximum one-way measurements from the chassis.
• Do not expose the equipment chassis to direct sunlight, high humidity, heat, dust, or
strong magnetic fields (such as those generated by heavy motors and large copy
machines).
• With a U.S. system, the MDF requires at least a 4 × 6-foot (1.2 × 1.8-meter), ¾-inch (2
cm) plywood backboard. This should provide sufficient room for all blocks and periph-
eral equipment.
NOTE: If installing a number of AC transformers and SLAs (along with their corre-
sponding modular jack assemblies) at the MDF, a larger backboard may be necessary.
• For cooling purposes, provide ample air space around the chassis assembly (minimum
one foot on all sides). Do not place or store items on top of the equipment chassis.
• The SMDR/error message output device(s) must not have cables longer than 50 feet (15
meters).
• Locate the equipment in a climate-controlled room with the following environmental
conditions.
