CHAPTER 17 FPS-T1U RACK INSTALLATION
17.1 GENERAL
This chapter contains instructions for initial inspection, preparation for use and repackaging for shipment.
In some sections in this chapter, where the instructions for the FPS-T1U and the FPS1000 are identical,
a reference to a section describing the FPS1000 will be given.
17.2 PREPARATION FOR USE
Table 10-1 below describes the basic setup procedure. Follow the instructions in Table 17-1 in the sequence
given to prepare the FPS-T1U rack for use.
17.3 INITIAL INSPECTION
Refer to Sec. 3.3 for details.
17.4 FPS-T1U RACK MOUNTING
The FPS-T1U is designed to be mounted in a 19" rack. Use a support bars or surface to provide adequate
support for the rear of the power supply. Secure the FPS-T1U to its location using the front panel using
M6x12 screws via the mounting holes at its front side (Refer to the outline drawings in Chapter 18).
Do not obstruct the air exhaust at the rear panel of the unit.
17.5 LOCATION MOUNTING AND COOLING
The FPS1000 units installed in the FPS-T1U rack are fan cooled. The air intake is at the front panel and
the exhaust is at the rear panel. Upon installation allow cooling air to reach the front panel and allow
minimum 50mm of unrestricted air space at the rear of the unit for the air exhaust.
17.6 AC SOURCE REQUIREMENTS
Refer to Sect 3.6 for details.
17.7 CONNECTING THE LOAD
WARNING
Turn off the AC input power before making or changing any rear panel connection.
Ensure that all connections are securely tightened before applying power. There is a
potential shock hazard when using a power supply with a rated output greater than 40V.
17.7.1 Load Wiring
Refer to Sec. 3.7.1, 3.7.2 and 3.7.3 for details.
17.7.2 Inductive loads
To prevent damage to the power supply from inductive kickback, a diode should be connected across the
output. The diode voltage and current rating should be greater than the power supply maximum output
voltage and total current rating. Connect the cathode to the positive output and the anode to the negative
output. Where positive load transients such as back EMF from a motor may occur, connect a surge
suppressor across the output to protect the power supply. The breakdown voltage rating of the suppressor
must be approximately 10% higher than the maximum output voltage of the power supply.
