Installation 

Intellijel

 

Eurorack

 

modules

 

are

 

designed

 

to

 

be

 

used

 

with

 

a

 

Eurorack-compatible

 

case

 

and

 

power 

supply. 
 

Before​ ​Your​ ​Start 

Before

 

installing

 

a

 

new

 

module

 

in

 

your

 

case

 

you

 

must

 

ensure

 

your

 

case’s

 

power

 

supply

 

has 

sufficient

 

available

 

capacity

 

to

 

power

 

the

 

module: 

 

● Sum

 

up

 

the

 

specified

 

+12V

 

current

 

draw

 

for

 

all

 

modules,

 

including

 

the

 

new

 

one.

 

Do

 

the 

same

 

for

 

the

 

-12

 

V

 

and

 

+5V

 

current

 

draw.

 

The

 

current

 

draw

 

will

 

be

 

specified

 

in

 

the 

manufacturer's

 

technical

 

specifications

 

for

 

each

 

module. 

● Compare

 

each

 

of

 

the

 

sums

 

to

 

specifications

 

for

 

your

 

case’s

 

power

 

supply. 

● Only

 

proceed

 

with

 

installation

 

if

 

none

 

of

 

the

 

values

 

exceeds

 

the

 

power

 

supply’s 

specifications.

 

Otherwise

 

you

 

must

 

remove

 

modules

 

to

 

free

 

up

 

capacity

 

or

 

upgrade

 

your 

power

 

supply. 

 
You

 

will

 

also

 

need

 

to

 

ensure

 

you

 

have

 

enough

 

free

 

space

 

(hp)

 

​​

 

as

 

well

 

as

 

free

 

power

 

headers

 

in 

your

 

case

 

to

 

fit

 

the

 

new

 

module. 

 
You

 

can

 

use

 

a

 

tool

 

like

 

​​

ModularGrid

 

to

 

assist

 

in

 

your

 

planning.

 

Failure

 

to

 

adequately

 

power

 

your 

modules

 

may

 

result

 

in

 

damage

 

to

 

your

 

modules

 

or

 

power

 

supply.

 

If

 

you

 

are

 

unsure,

 

please 

contact

 

us

 

before

 

proceeding. 

Installing​ ​Your​ ​Module 

When

 

installing

 

or

 

removing

 

a

 

module

 

from

 

your

 

case

 

always

 

turn

 

off

 

the

 

power

 

to

 

the

 

case

 

and 

disconnect

 

the

 

power

 

cable.

 

Failure

 

to

 

do

 

so

 

may

 

result

 

in

 

serious

 

injury

 

or

 

equipment

 

damage. 

 
Ensure

 

the

 

10-pin

 

connector

 

on

 

the

 

power

 

cable

 

is

 

connected

 

correctly

 

to

 

the

 

module

 

before 

proceeding.

 

The

 

red

 

stripe

 

on

 

the

 

cable

 

must

 

line

 

up

 

with

 

the

 

-12V

 

pins

 

on

 

the

 

module’s

 

power 

connector.

 

The

 

pins

 

are

 

indicated

 

with

 

the

 

label

 

-12V,

 

a

 

white

 

stripe

 

next

 

to

 

the

 

connector,

 

the 

words

 

“red

 

stripe”,

 

or

 

some

 

combination

 

of

 

those

 

indicators.
