should

 

be

 

transported

 

within

 

original

 

package

 (

packed

 

in

). 

The

 

product

 

should

 

be

 

handled

 

carefully

 

during

 

transportation

to

 

prevent

 

the

 

capacitor

 

body

 

from

due

 

to

The

should

 

be

 

placed

 

on

 

upper

 

level

 

when

 

loaded

 

onto

 

the

 

truck

The

 

capacitor

during

 

transportation

with

 

an

less

 

than
