INSTRUCTION MANUAL

Checking Transformer

1. Turn off power.

2. Locate the leads to be tested.

3. S e p a r ate the remaining leads in the primary so they do not
short out.

4. Obtain an AC volt meter or multi-tester than can measure at
least 30 volts.

5. Apply the correct voltage to the primary side of the transformer.

6. With the AC volt meter, measure the voltage across the
secondary leads using the following table.

NOTE: No-load voltage reading may be slightly higher than the above
stated voltages.

7. If incorrect readings are measured, immediately disconnect the
voltage to the primary and recheck all connections.

8. Check the fuse in line with the blue lead in the secondary making
sure it is good. If not, replace only with a 3.15 Amp/250 Volt
slow blow fuse.

9. Reapply the voltage to the primary. If incorrect readings continue
to be measured, obtain a new transformer.

10. If correct readings are measured, disconnect power to the
primary and proceed to install the transformer.

Mounting

The UET175 is designed for foot mounting. Four mounting screws are
provided (Fig 2).

Introduction

The UET 175 is used for 24V control circuits to protect equipment or
minimize shock hazard. Rating not to exceed 75 VA .

Features include

• Primary and secondary wires are color coded for easy hookup

• Includes: Fuse, 6 wire nuts, and 4 mounting screws

Safety Notes

CAUTION!

1. Transformer should be installed by a trained, experienced
serviceman.

2. Power should be disconnected before beginning installation
to prevent electrical shock or equipment damage.

3. Wiring must comply with local codes and ordinances.

4. All unused exposed leadwires should be taped or insulated.

5. Check thoroughly after installing.
