Chapter 1: Safety Information

In order to achieve the optimum, safe operation of the PSS power supply, it is imperative
that you implement the safety procedures included in this user guide. This information is
provided to protect you and to keep your work area safe when operating the PSS and
accompanying equipment. Read this chapter carefully before you begin the installation
process.

Only qualified personnel may install, adjust, maintain and repair the power supply. A
“qualified person” has the knowledge and authorization to perform tasks such as
transporting, assembling, installing, commissioning and operating motors.

The PSS power supply contains electrostatic-sensitive components that can be damaged if
handled incorrectly. To prevent any electrostatic damage, avoid contact with highly
insulating materials, such as plastic film and synthetic fabrics. Place the product on a
conductive surface and ground yourself in order to discharge any possible static
electricity build-up.

1-1

To avoid any potential hazards that may cause severe personal injury or damage to the
product during operation, keep all covers and cabinet doors shut.

The following safety symbols are used in this manual:

Warning:
This information is needed to avoid a safety hazard, which might cause
bodily injury.

Caution:
This information is necessary for preventing damage to the product or to
other equipment.

Note:

This is auxiliary information that ensures the correct operation of the
equipment.

1.1 Warnings

To avoid electric arcing and hazards to personnel and electrical contacts,
never connect/disconnect the power supply while the power source is on.

Power cables can carry a high voltage, even when the motor is not in
motion. Disconnect the PSS from all voltage sources before it is
disassembled for servicing.

After shutting off the power and removing the power source from your
equipment, wait at least 5 minutes before touching or disconnecting parts
of the equipment that are normally loaded with electrical charges (such as
capacitors or contacts). Measuring the electrical contact points with a
meter before touching the equipment is recommended.

1.2 Cautions

The PSS contains hot surfaces and electrically-charged components during
operation.

The maximum AC power supply connected to the instrument must comply
with the parameters outlined in this guide.

1.3 Warranty Information

The products covered in this manual are warranted to be free of defects in material and
workmanship and conform to the specifications stated either within this document or in
the product catalog description. All Elmo products are warranted for a period of 12
months from the time of installation, or 18 months from time of shipment, whichever
comes first. No other warranties, expressed or implied — and including a warranty of
merchantability and fitness for a particular purpose — extend beyond this warranty.

Chapter 2: Product Description

The PSS and PSSF power supplies were designed to complement Elmo servo amplifiers
that do not include an integrated power supply. All PSS/PSSF models include shunt
regulators and feature high capacitance, a low profile and snap-in capacitors. The PSSF
supply requires fan cooling. The power supplies are built around two basic sizes: Eurocard
(3U) and double Eurocard (6U). Two mounting versions are available:

 Surface mount version - has 4 thru-holes for screw assembly

 Panel mount version - connects to 19-inch rack with drop-on slots and connects electrically

via DIN 41612 backplane connectors

All Eurocard (3U) power supplies are shipped for single-phase connections, although they
include a built-in three-phase option. The shunt regulator, included with the PSS and PSSF
supply, is designed for use with high-inertia loads. These supplies incorporate thermal and
duty-cycle protections.

Function Comment

AC-1 supply input (through
an isolated/floating
transformer)

In single-phase connections (of PSS type 3U),
this terminal is internally shorted to terminal
1 by W2. The power supply is modified for
three-phase connections by removing W2
and connecting the third phase to terminal 1.

AC-3 supply input (through
an isolated/floating

For DIN mounting, all four pins must be
connected.

5* 6a, 4c Inhibit indication return Internally connected to power output common.

6* 4a Inhibit indication output Whenever power supply is inhibited (e.g.

during thermal/duty cycle), this open
collector output goes into low state
(maximum sink current: 10 mA, 30 VDC).
