Mounting the Drive
You can mount your drive on the wide or the narrow side of the chassis using #6 screws. If
possible, the drive should be securely fastened to a smooth, flat metal surface that will help
conduct heat away from the chassis. If this is not possible, then forced airflow from a fan may
be required to prevent the drive from overheating. See page 40 for more details about drive
heating.
• Never use your drive in a space where there is no air flow or where other devices
cause the surrounding air to be more than 50°C.
• Never put the drive where it can get wet or where metal or other electrically con-
ductive particles can get on the circuitry.
• Always provide air flow around the drive. When mounting multiple drives near
each other, maintain at least one half inch of space between drives.
Connecting the Power Supply
If you need information about choosing a power supply, please read the section Choosing a
Power Supply.
• Connect the power supply “+” terminal to the connector terminal labeled “V+”.
• Connect power supply “-” to the connector terminal labeled “V-”.
• The green ground screw on the corner of the chassis should be connected to earth ground.
• Use 18 or 20 gauge wire.
The STR drives contain an internal fuse that connects to the power supply + terminal. This fuse
is not user replaceable. If you want to install a user serviceable fuse in your system install a fast
acting fuse in line with the + power supply lead. Use a 4 amp fuse for the STR4 and a 7 amp
fuse for the STR8. Some HT24 motors draw more than 4 amps, a 7 amp fuse is recommended
for all drives in this case.
Be careful not to reverse the wires. Reverse connection will destroy your
drive, void your warranty and generally wreck your day.
