fulll all the 120 Vac and 24 Vac*(Class 2) power require-
ments needed inside a building automation (BAS) panel,
industrial enclosure, or other general purpose electrical
enclosure, in addition to on/o control, equipment over-
current protection, power indication, high/low voltage
separation, and convenience receptacles. They are also
useful for many applications outside of BAS.

Mounting
1. Remove the entire front cover (PSC versions) by extracting 2 screws on top front.
2. Attach uncovered power supply using 4 screw holes.
3. Make desired wire connections.
4. Reattach cover for PSC versions.
Wiring
All wiring must comply with local codes and ordinances. Disconnect power before making wiring connections to prevent
electrical shock or equipment damage.

1. Bring wiring into 1 of the 2 openings on the side of the power supply while cover is removed (PSC version).
2. Make appropriate connections to the terminal strips.
Note: All eld wire leads are intended for installation inside the enclosure.
Voltage Check
After installation is complete, turn on power supply and perform a voltage check:
1. Place controlled equipment in operation and observe through one complete cycle.
2. Using a voltmeter, check for proper primary and secondary voltages.
3. If voltage readings are incorrect, be sure primary voltage connections are made correctly.
4. Measure voltage again:
a. If correct primary voltage is measured and secondary voltage is signicantly less than the voltage shown on the
regulation curves, transformer winding is damaged. Replace transformer and repeat checkout procedures.
b. If primary voltage is 0V, be sure power supply is connected correctly or repair, if necessary. Repeat checkout
procedures.
