3. How to Install
NOTE
To install the indicator, select a location where:
(1) no one may accidentally touch the terminals,
(2) mechanical vibrations are minimal,
(3) corrosive gas is minimal,
(4) temperature can be maintained at about 23°C and the fluctuation is minimal,
(5) no direct radiant heat is present,
(6) no magnetic disturbances are caused,
(7) no wind blows against the terminal board (reference junction compensation
element),
(8) no water is splashed,
(9) no flammable materials are around,
Never place the indicator directly on flammable items or equipment.
If the indicator has to be installed close to flammable items or equipment, be sure to provide shielding panels all
around the indicator, at least 150mm away from every side; the panels should be made of either 1.43mm-thick
metal-plated steel plates or 1.6mm-thick uncoated steel plates.
NOTE
Never touch the opening at the bottom of the case. It is to be used in the factory at shipping.
●Installation Position
Install the indicator at an angle within 30°from horizontal with
the front panel facing upward. Do not install it facing down-
ward. The position of right and left sides should be horizontal.

After opening the mounting hole on the
panel, follow the procedures below to in-
stall the indicator:
1. Insert the indicator into the opening
from the front of the panel so that the
terminal board on the rear is at the far
side.
2. Set the brackets in place on the top and
bottom of the indicator as shown in the
figureonthe left, then tighten the screws
of the brackets. Take care not to over-
tighten them.
Note: Right and left mounting for UM330.
4. How to Connect Wires
CAUTION
1) Before carrying out wiring, turn off the power to the indicator and check that the cables to be connected are not
alive with a tester or the like because there is a possibility of electric shock.
2) For the protection and safe use of the indicator, be sure to place a circuit breaker (conforms with IEC60947,
5A, 100V or 220V AC) near the indicator where the breaker can easily be operated. In addition, be sure to
indicate that it is the instrument to cut the power supply of the indicator.
3) Wiring must be carried out by personnel who have basic electrical knowledge and practical experience.
NOTE
1) Provide power from a single-phase instrument power supply. If there is a lot of noise in the power line, insert an
insulating transformer into the primary side of the line and use a line filter (recommended part: ZAC2205-00U
from TDK) on the secondary side.
As a countermeasures against noise, do not place the primary and secondary power cables close to each other.
2) For thermocouple input, use shielded compensating lead wires for wiring. For RTD input, use shielded wires
that have low conductor resistance and cause no significant differences in resistance between the three wires.
The cables to be used for wiring, terminal specifications, and recommended parts are as shown below.
3) Alarm output relays have a life of 100,000 times that of the resistance load, use auxiliary relays to turn on/off
a load.
4) The use of inductance (L) loads such as auxiliary relays, motors and solenoid valves causes malfunction or
relay failure; always insert a CR filter for use with alternating current or a diode for use with direct current, as
a spark-removal surge suppression circuit, into the line in parallel with the load.
5) When there is possibility of being struck by external lightening surge, use the arrester to protect the instrument.

■How to Install
CAUTION
Turn off the power to the indicator before installing it on the panel because there is a possibility of electric shock.
Fold the cover in the direction
of the arrow.
Fit the cover hold
over the protrusion
on the mounting bracket.
Figure A
Figure B
1. Before attaching the terminal cover, bend the side with
the groove inward as shown in Fig.A. Be careful not to
bend it backwards. This not only makes it harder to
attach the cover but will also weaken its hold.
2. Fit the holes on the top and bottom (or left and right) of
the terminal cover over the projections on the brackets
(Fig. B) and lock in place. The figure right shows the
attachment of a terminal cover to UM indicator.
Note:Right and left mounting for UM330.

This manual describes examples of setting the types of PV input and alarm. Carrying out settings described herein allows
you to perform basic monitoring. Refer to examples of various settings to understand how to set parameters required. Refer
to “1. Parameter Map” in Parameters User’s Manual for an easy to understand explanation of setting various param-
eters. If you cannot remember how to carry out an operation during setting, press the
SET/ENT
key for more than 3 seconds.
This brings you to the display (operating display) that appears at power-on.

IMPORTANT
The indicator automatically returns to the display at the time of power-on (i.e., Operating display) if no key is
operated for at least one minute.
2. Setting PV Input Type (Setting First at Power-on)
NOTE
• The indicator displays the operating display when the power is turned on. However, if PV input type has not
been set, “IN” appears. In this case, first use the key to
display the input range code to use, then press the
SET/ENT
key
to register it.Then, set the maximum value (RH) and minimum
value (RL) of the PV input range (for voltage input, set the
maximum value (SH) and minimum value (SL) of the PV input
scale).
• The indicator is configured to the initial value of each param-
eter at the factory before shipment.
First check the initial values shown in 2. Lists of Parameters, in Parameters User’s Manual and change
parameter values as necessary.

■If a Power Failure Occurs during Operation
●Momentary power failures shorter than 20 ms
The indicator is not affected at all and continues normal operation.
●Momentary power failures of 20 ms or longer
• The alarm function of the indicator continues to work normally. (Alarms with the stand-by feature temporarily return to
their stand-by state, however.)
• Setting parameters that have already been configured retain their settings.

NOTE
Changing the registered value of a setup parameter
may cause the registered value of an operating pa-
rameter to be initialized automatically. Thus, when
you have changed a setup parameter, always check
that the registered value of the operating parameter
is appropriate. If it is initialized to default, reset it to
the required value.
