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.

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.

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 install

a

tion 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 Genesys

TM

series can be operated from a nominal 208V, 400V or 480V thr

ee phase, 4 wire, 47



63

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 pr

o

tection (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 shou

ldbe made by an electrician or

other

qualified personnel. Do not

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

3.9.2

Noise and Impedance E

f

fects

To minimize the noise pickup or r

a

diation, the load wires and remote sense wires should be twisted

pairs to the shortest possible length. Shielding of sense leads may be necessary in high noise

env

i-

ronments. Where shielding is used, co

n

nect the shield to the chassis via a rear panel Ground screw.

Even if noise is not a concern, the load and remote sense wires should be twisted

-

pairs to reduce co

u-

pling, which might impact the stability of power su

pply. The sense leads should be sep

a

rated from the

power leads.

Twisting the load wires reduces the parasitic inductance of the cable, which could produce high fr

e-

quency voltage spikes at the load and the output of power supply, because of current variati

on in the

load itself.

The impedance introduced between the power supply output and the load could make the ripple and

noise at the load worse than the noise at the power supply rear panel output. Additional filtering with

bypass capacitors at the load te

r

minals may be required to bypass the high frequency load current.

3.9.3

Inductive loads

Inductive loads can produce voltage spikes that may be harmful to the power supply. A diode should

be connected across the output. The diode voltage and current ratin

g should be greater than the power

supply maximum output voltage and current rating. Connect the cathode to the positive output and the

anode to the negative output of the power supply.

Where positive load transients such as back EMF from a motor may occur

, connect a surge suppre

s-

sor across the output to protect the power supply. The breakdown voltage rating of the suppressor

must be a

p

proximately 10% higher than the maximum output voltage of the power supply.

Connecting single loads, local sensing (defaul

t).

Connecting single loads, remote sensing

Fig.3

-

11 shows recommended remote sensing connection for single loads. Remote sensing is used

when, in Co

n

stant Voltage mode, the load regulation is important at t

he load terminals. Use twisted or

shielded wires to minimize noise pick

-

up. If shielded wires are used, the shield should be connected to

the ground at one point, either at the power supply chassis or the load ground. The optimal point for

the shield groun

d should be determined by experime

n

tation.
