Nomenclature
Note: 1. The fuse is located on the (L) side. It is NOT user-replace-
able.
2. If mounting is performed using a DIN Rail, the protective
earthing connection is the panel mounting hole shown in the
figure below.
(A protective earthing connection stipulated in safety stan-
dards is used. Connect the ground completely (S8VM-
@@@@@
D only)).

only. Housing and terminals of the connector
for undervoltage detection output are also provided. For de-
tails, refer to Undervoltage Alarm Output Connector Har-
ness Manufacture Method on page 33 under Safety
Precautions.
5. When not using the remote sensing function, leave the short
bar in the same state as when shipped.

Connect the ground line to this
terminal. (See note 2.)
3
DC output terminals (-V), (+V)
Connect the load lines to these
terminals.
4
Output indicator (DC ON: Green)
Lights (green) while a direct
current (DC) output is ON.
5
Output voltage adjuster (V. ADJ)
Use to adjust the voltage.
6
Undervoltage alarm indicator 1
(DC LOW1: Yellow) (See note 3.)
Lights only when a momentary
drop in output voltage is de-
tected. This status is main-
tained.
7
Undervoltage alarm indicator 2
(DC LOW2: Red) (See note 3.)
Lights only when the output
voltage drops to approximately
20 V or lower.
8
Undervoltage alarm output terminal 1:
(DC LOW1) (See note 4.)
Outputs only when a momen-
tary drop in output voltage is
detected. This status is main-
tained.
(The transistor turns OFF
when a voltage drop occurs.)
9
Undervoltage alarm output terminal 2:
(DC LOW2) (See note 4.)
Outputs only when the output
voltage drops to approximately
20 V or lower.
(The transistor turns OFF
when a voltage drop occurs.)
10
Common terminal for undervoltage alarm
output (See note 4.)
Common terminal (See note
6.) for terminals 8 and 9
11
Remote sensing terminals (See note 5.)
Correct the voltage drop in the
load lines.
