CHAPTER 3 INSTALLATION
3.1 GENERAL
This Chapter contains instructions for initial inspection, preparation for use and repackaging for ship-
ment. Connection to PC, setting the communication port and linking GenesysTM power supplies are de-
scribed in Chapter 7.
3.2 PREPARATION FOR USE
In order to be operational the power supply must be connected to an appropriate AC source. The AC
source voltage should be within the power supply specification. Do not apply power before reading
Section 3.6 and 3.7.
Table 3-1 below, describes the basic setup procedure. Follow the instructions in Table 3-1 in the se-
quence given to prepare the power supply for use.

3.3 INITIAL INSPECTIONS
Prior to shipment this power supply was inspected and found free of mechanical or electrical defects.
Upon unpacking of the power supply, inspect for any damage, which may have occurred in transit.
The inspection should confirm that there is no exterior damage to the power supply such as broken
knobs or connectors and that the front panel and meters face are not scratched or cracked. Keep all
packing material until the inspection has been completed. If damage is detected, file a claim with carrier
immediately and notify the Lambda sales or authorized service facility nearest you.
3.4 RACK MOUNTING
The GenesysTM power supply series is designed to fit in a standard 19” equipment rack.
3.4.1 To install the Power Supply in a rack:
1. Use the front panel rack-mount brackets to install the power supply in the rack.
2. Use a support bar to provide adequate support for the rear of the power supply. Do not obstruct the
air exhaust at the rear panel of the unit.
GenesysTM power supplies generate magnetic fields, which
might affect the operation of other instruments. If your equip-
ment is susceptible to magnetic fields, do not position it adja-
cent to the power supply.

83-530-000 Rev. B
15
Some components inside the power supply are at AC/DC
voltage even when the On/Off switch is in the “Off” position. To
avoid electric shock hazard, disconnect the line and load and
wait 15 minutes before removing cover.
There is a potential shock hazard if the power supply chassis
(with cover in place) is not connected to an electrical safety
ground via the safety ground in the AC input stud terminals.
3.5 LOCATON, MOUNTING AND COOLING
This power supply is 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 ventilation inlets. Unrestricted air space at
the front and the rear of the unit is necessary for proper cooling of power supply.
3.6 AC SOURCE REQUIREMENTS
The GenesysTM series can be operated from a nominal 208V, 400V or 480V three phase, 4 wire, 47i63
Hz. The input voltage range and current required for each model is specified in Chapter 2. Ensure that
under heavy load, the AC voltage supplied to the power supply does not fall below the specifications
described in Chapter 2.
3.7 AC INPUT POWER CONNECTION
The customers AC line connects to the power supply through four stud type terminals. Only use a
power cable with the correct voltage and current ratings. The recommended wire gauge is listed in the
table in section 3.7.1. The ground wire must be equal to or larger than the recommended gauge for
phase. The power supply must be permanently connected to an approved AC distribution box with
suitably rated overcurrent protection (60Amp UL Listed fuse for 208V input, and 40 Amp UL listed fuse
for 400/480 input).
Connection of this power supply to an AC power source should
be made by an electrician or other qualified personnel. Do not
exceed the torque specified on input stud terminals.

WARNING
Turn Off the AC input power before making or changing any rear panel
connection. Ensure all live circuits are discharged and 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.
When local sensing, a short from +LS or +S to -V or -S or -LS,
will cause damage to the power supply. Reversing the sense
wires might cause damage to the power supply in local and
remote sensing. (Do not connect -S to +V or +S to -V).
3.9 CONNECTING THE LOAD
The load cables between the power supply outputs and the load must be a specified. The cable con-
nections must be secured to required torque spec. Failure to meet these requirements could cause
substantial voltage losses, terminal over-heating, and insulation degradation.
