Rear Panel

) AC IN connectors

Use these sockets to connect the supplied power

cords. First connect the AC power cords to this unit,

and then insert the power cord plugs into AC outlets.

Insert the cord plugs all the way until they lock in

place securely. The supplied AC power cords feature a

Vlock mechanism via a latch, which prevents the

power cords from disconnecting accidentally.

NOTE

Be sure to connect the power cords to power supply units

A and B. In this way, if one of the power supply units

malfunctions, the other unit will supply power to continue

the operation.

CAUTION

Be sure to turn off the power to the unit before connecting

or disconnecting the power cord.

To disconnect the power

cord, remove it while

pressing the latch on the

plug.

! Vent

This unit is equipped with cooling fans. These vents

let warm air out from the unit. Please make sure that

you do not block the vents with any object.

@ [FAULT OUTPUT] connectors

This Euroblock connector is used to send an

indication of abnormality to the outside of the unit.

Connect a lamp or buzzer here. The NC and C

terminals will short-circuit if the unit is operating

normally. The NO and C terminals will short-circuit

if an abnormality is detected.

NOTE

The NO and C terminals will also short-circuit if you

intentionally turn off the power to the unit, just as they will if

a problem with power occurs.
