3.Voltage to compressor terminals during operation must be within voltage range indicated on unit nameplate (also see Tables 3A and 3B). On 3-phase units, voltages be- tween phases must be balanced within 2% and the cur- rent within 10%. Use the formula shown in Tables 3A and 3B, Note 2, to determine the percent voltage im- balance. Operation on improper line voltage or exces- sive phase imbalance constitutes abuse and may cause damage to electrical components. Such operation would invalidate any applicable warranty.

4.Insulate low-voltage wires for highest voltage con- tained within conduit when low-voltage control wires are run in same conduit as high-voltage wires.

5.Do not damage internal components when drilling through any panel to mount electrical hardware, conduit, etc.

NOTE: If accessory thru-the-bottom connections and roof curbs are used, refer the Thru-the-Bottom Installation Instruc- tions for information on power wiring.
