properly connected to its connector.

Moving an array

Observe the following when moving an array.

Before starting relocation/removal

Read and follow the safety instructions located in the Preface of this manual.
Note the following caution before starting installation or moving an array.
CAUTION! Generally, each part is equipped with high-precision
components. Remove and install the part gently to prevent
mechanical shock to the parts.
To prevent part failures caused by static electricity, wear an anti-
static wrist strap connected to the chassis before starting work
and do not take it off until you finish. This includes unpacking and
any time you handle static-sensitive parts.
When you install a disk drive, control unit, or ENC unit, support its metal
part with your hand that has the wrist strap. You can discharge static
electricity by touching the metal plate.
Support the part by touching its
metal part (metal plate) with your
fingers
