Fiberplex WDM16, User Manual

Ambient

Temperature

Units

and

systems

by

FiberPlex

are

generally

designed

for

an

ambient

temperature

range

(i.e.

temperature

of

the

incoming

air)

of

5

°C

to

40

°C

(41

°F

to

104

°F).

When

rack

mounting

the

units,

the

following

facts

must

be

considered:



The

permissible

ambient

temperature

range

for

operation

of

the

semiconductor

components

is

0

°C

to

+70

°C

(32

°F

to

158

°F)

(commercial

temperature

range

for

operation).



The

airflow

through

the

installation

must

allow

exhaust

air

to

remain

cooler

than

70

°C

(158

°F)

at

all

times.



Average

temperature

increase

of

the

cooling

air

shall

be

about

20

°C

(68

°F),

allowing

for

an

additional

maximum

10

°C

increase

at

the

hottest

components.



In

order

to

dissipate

1

kW

with

this

permissible

average

temperature

increase,

an

air

flow

of

2.65

m³/min

is

required.

Example:

A

rack

dissipating

P

=

800

W

requires

an

air

flow

of

0.8

*

2.65

m³/min

which

corresponds

to

2.12

m³/min.



If

the

cooling

function

of

the

installation

must

be

monitored

(e.g.

for

fan

failure

or

illumination

with

spot

lamps),

the

exhaust

air

temperature

must

be

measured

directly

above

the

modules

at

several

places

within

the

enclosure.

Grounding

and

Power

Supply

Grounding

of

units

with

mains

supply

(Class

I

equipment)

is

performed

via

the

protective

earth

(PE)

conductor

integrated

in

three

‐

pin

Phoenix™

connector.

Units

with

battery

operation

(<

60

V,

Class

III

equipment)

must

be

earthed

separately.

Grounding

the

unit

is

one

of

the

measures

for

protection

against

electrical

shock

hazard

(dangerous

body

currents).

Hazardous

voltage

may

not

only

be

caused

by

defective

power

supply

insulation,

but

may

also

be

introduced

by

the

connected

audio

or

control

cables.

This

equipment

may

require

the

use

of

a

different

line

cord,

attachment

plug,

or

both,

depending

on

the

available

power

source

at

installation.

If

the

attachment

plug

needs

to

be

changed,

refer

servicing

to

qualified

personnel.

Class

I

Equipment

(Mains

Operation)

Should

the

equipment

be

delivered

without

a

matching

mains

cable,

the

latter

must

be

prepared

by

a

trained

person

using

the

attached

female

plug

(Neutrik™

powerCON

TRUE1)

with

respect

to

the

applicable

regulations

in

your

country.

Before

connecting

the

equipment

to

the

AC

power

outlet,

check

that

the

local

line

voltage

matches

the

equipment

rating

(voltage,

frequency)

within

the

admissible

tolerance.

The

equipment

fuses

must

be

rated

in

accordance

with

the

specifications

on

the

equipment.

Equipment

supplied

with

a

3

‐

pole

appliance

inlet

(protection

conforming

to

class

I

equipment)

must

be

connected

to

a

3

‐

pole

AC

power

outlet

so

that

the

equipment

cabinet

is

connected

to

the

protective

earth.

WARNING:

If

the

ground

is

defeated,

certain

fault

conditions

in

the

unit

or

in

the

system

to

which

it

is

connected

can

result

in

full

line

voltage

between

chassis

and

earth

ground.

Severe

injury

or

death

can

then

result

if

the

chassis

and

earth

ground

are

touched

simultaneously.
