Page 2: General Safety Guidelines
General safety guidelines Important: Read before proceeding. This equipment is a relatively complicated apparatus. During rigging, installation, operation, maintenance, or service, individuals may be exposed to certain components or conditions including, but not limited to: heavy objects, refrigerants, materials under pressure, rotating components, and both high and low voltage. - Page 3 All wiring must be in accordance with Johnson Controls’ published specifications and must be performed only by a qualified electrician. Johnson Controls will not be responsible for damage/problems resulting from improper connections to the controls or application of improper control signals.
- Page 4 Conduit is not an acceptable means for grounding. See Table for auxiliary panel ground lug sizing. Johnson Controls does not provide wiring, electrical conduit, junction boxes, fused disconnect switches (FDS) or circuit breakers, starters (M), pushbutton stations (PB), manual-off- automatic switch (S), flow switch (FLS), and control relays, unless otherwise specified.
- Page 5 Figure shows the location of the removable conduit plate. Do not penetrate the auxiliary panel, except to the conduit plate when it is removed from the auxiliary panel enclosure. No other customer connections are provided in the auxiliary panel enclosure. DANGER Failure to correctly make conduit openings, cut power wire, or any method of making additional holes in the enclosure may result in an arc flash event, damage to equipment, injury of...

- Page 7 16. The maximum line voltage imbalance is 5%. The voltage imbalance is calculated as the difference between any of the three line voltages and the average of the three line voltages, and multiplied by 100%. The maximum line voltage total harmonic distortion (THD) is 5% for each phase, from n=2nd to n=50th harmonic, when line impedance is specified as follows: The minimum value of line impedance is determined by the case where the chiller's power is provided from a transformer with a kVA rating equal to five times the rated...
- Page 8 WARNING Removable conduit plate where power conduit must be installed. The plate must be removed before cutting conduit holes. Failure to remove the plate when cutting the conduit holes requires replacement of the auxiliary panel at a cost outside of warranty.
