1.2 How to Install
NOTE
To install the indicator, select a location where:
1. no one may accidentally touch the terminals,
150 mm150 mm
150 mm
150 mm
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 pro-
vide shielding panels all around the indicator, at least 150 mm away from every side; the
panels should be made of either 1.43 mm-thick metal-plated steel plates or 1.6 mm-thick
uncoated steel plates.
NOTE
Never touch the opening at the bottom of the case. It is to be used in the factory at ship-
ping.
●Installation Position
Install the indicator at an angle within 30from horizontal with the front panel facing up-
ward. Do not install it facing downward. The position of right and left sides should be hori-
zontal.
Front panel

■How to Install
CAUTION
Turn off the power to the indicator before installing it on the panel because there is a possi-
bility of electric shock.
After opening the mounting hole on the panel, follow the procedures below to install 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 figure
below, then tighten the screws of the brackets. Take care not to overtighten them.

Direction to insert the
indicator

the front of the panel.
Note: Right and left mounting for UM330.

1.3 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) 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.

CAUTION
Before carrying out wiring, turn off the power
to the indicator and check that cables to be
connected are not alive with a tester or the like
because there is a possibility of electric shock.
