Start Up - Trane TR200 Operating Instructions Manual

Start Up

Pre-start Procedure
1. Input power to unit must be OFF and locked out per OSHA requirements. Do not rely on panel disconnect
switches.
HIGH VOLTAGE! IF INPUT AND OUTPUT CONNECTIONS HAVE BEEN CONNECTED IMPROPERLY, THERE IS
POTENTIAL FOR HIGH VOLTAGE ON THESE TERMINALS. IF POWER LEADS FOR MULTIPLE MOTORS ARE
IMPROPERLY RUN IN SAME CONDUIT, THERE IS POTENTIAL FOR LEAKAGE CURRENT TO CHARGE CAPAC-
ITORS WITHIN OPTION PANEL, EVEN WHEN DISCONNECTED FROM LINE INPUT. FOR INITIAL START UP,
MAKE NO ASSUMPTIONS ABOUT POWER COMPONENTS. FOLLOW PRE-START PROCEDURES DESCRIBED
BELOW. FAILURE TO FOLLOW PRE-START PROCEDURES DESCRIBED BELOW COULD RESULT IN PERSONAL
INJURY OR DAMAGE TO EQUIPMENT.
1. Use AC voltmeter to verify there is no voltage on input terminals L1, L2, and L3, phase-to-phase and phase-
to-ground, and output terminals T1, T2, and T3, phase-tophase and phase-to-ground.
2. Use ohmmeter to confirm continuity of motor by measuring T1-T2, T2-T3, and T3-T1.
3. Use ohmmeter to confirm open on input by measuring L1-L2, L2-L3, and L3-L1. Note that if an isolation
transformer is between the power source and panel, continuity will be present. In this case, visually confirm
that motor and power leads are not reversed.
4. Inspect the panel for loose connections on terminals.
5. Check for proper ground: option panel to main building distribution ground, and option panel to motor
ground. See label inside panel cover for proper wire size.
6. Confirm control connections terminated per connection diagrams supplied with the equipment.
7. Check for external devices between drive option panel output and motor. It is recommended that no devices
be installed between motor and drive.
8. Record motor nameplate data; hp, voltage, full load amps (FLA), and RPM. It will be needed to match motor
and drive later on.
9. Confirm that incoming power voltage matches drive label voltage and motor nameplate voltage.
10. For multiple winding motors, motor must be wired on run winding, not start winding.
CAUTION EQUIPMENT DAMAGE! IF MOTOR FLA (FULL LOAD AMPERAGE) IS GREATER THAN UNIT MAXIMUM
AMPS, DRIVE AND OPTION PANEL MUST BE REPLACED WITH ONE OF APPROPRIATE RATING. DO NOT ATTEMPT
TO RUN UNIT. FAILURE TO MATCH FLA TO UNIT MAXIMUM AMP RATING MAY RESULT IN EQUIPMENT DAMAGE.
1. Confirm motor FLA is equal to or less than maximum option panel output current. Some motors have higher
then normal NEMA currents.
2. Check that overload relay(s) is set for FLA of connected motor. Service factor is built into overload relay.
3. For drive start up procedures, see drive instruction manual.
Inspection Prior to Start Up
Before applying power to the unit, inspect the entire installation as detailed in table below.
