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)).
Ground terminal: M3 (Depth: 8 mm max.)/Ground wire:
AWG 18

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.
