Warnings
• Obey local regulations if they are stricter than the regulations mentioned in this
document.
• Obey the applicable electrical directives when installing and connecting the
compressor to the power circuit:
• CSA/UL
• UL: UL508A
• CSA: C22.2
• Do not allow voltage drops that exceed 10% of the nominal supply voltage to allow
safe shutdown of the installation within 0.4 s
• Apply the listed cable sections on main supply cables AND earth cable.
• Do not exceed the ambient temperature listed in the Limits section to avoid cable
damage.
• Mount all cables on a horizontally ventilated cable tray.
• Do not stack or group cables as this avoids heat dissipation.
• Connect the power cable with the correct (CSA certified) cable lugs on the
terminals in the electrical cabinet.
• Respect a minimum distance of 10 mm (0.4") between stripped cable ends.
• Use only the prescribed cable types:
• CSA-UL: (R, RW, T) multicore 110 °C (230 °F)
