SMART TRAC AC1
Technical Manual TM 3554-000 Smart Trac AC1 Installation
••
4-3
Consider the following when planning the installation and installing your Smart
Trac AC1:
•
Always lift your Smart Trac AC1 by its base, never by the front cover.
•
Install the Smart Trac AC1 on a flat, non-flammable vertical surface
(wall or panel) using mounting screws specified (See "Smart Trac AC1
Dimensions" for screw specifications).
•
Provide a minimum 4.7" (26.1cm) clearance above and below the
Smart Trac AC1. This allows for proper air circulation over the heat
sink fins.
•
Provide a minimum 1.2" (3.05cm) clearance on each side of the Smart
Trac AC1.
•
Mount your Smart Trac AC1 in a freestanding floor-mount cabinet.
Sufficient clearance must be obtained to permit the door to be opened.
•
Add a fan or cooling device as necessary to ensure air entering the
Smart Trac AC1 is below 113° F. (45° C) for protected chassis or
below 104° F. (40° C) for NEMA 1.
See "Table 1. Smart Trac AC1
Specifications".
Complete wire interconnections per information Table 2 and Table 3, Table 4 or
Table 5 , depending on the voltage of your Smart Trac AC1. Always adhere to
the following:
WARNING WARNING
Wiring should be performed only by qualified personnel.
Disconnect all power to Smart Trac AC1. Do not remove the front
cover while input power is ON.
Never connect the main circuit output terminals T1, T2 and T3 to
the AC main circuit power supply.
Failure to comply with this warning may result in damage to the
Smart Trac AC1 and connected equipment along with personal
injury and/or death.
•
Use 600V vinyl-sheathed wire or equivalent.
•
Determine wire size to consider voltage drop of leads.
•
Wire size must be suitable for NEC Class I Circuits.
•
Use UL approved closed loop connectors or CSA certified ring
connectors sized for the selected wire gauge. Install connectors using
only the connector manufacturer's recommended crimp tool.
See Table
2.
•
Motor lead length should not exceed 164 feet (50 meters). Motor
wiring should be run in a separate conduit from the power wiring. If
lead length must exceed this distance, reduce the carrier frequency and
consult the motor manufacturer for proper installation procedures.
•
Never connect AC main power to drive output terminals T1(U), T2(V),
T3(W).
