Reference Description
(7) Service mode
To preserve the protection degree of the electric cubicle and to protect its components
from dust from the environment, it is mandatory to use a proper cable gland when
connecting the supply cable to the compressor.
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:
• IEC 60204-1
• IEC 60364-5-52
• CSA/UL
• UL: UL508A
• CSA: C22.2
• The voltage on the compressor terminals must not deviate more than 10% of the
nominal voltage. It is however highly recommended to keep the voltage drop over
the supply cables at nominal current below 5% of the nominal voltage (IEC
60204-1).
• Use the original cable entry.
• Full load (compressor) package currents are calculated and available on Technical
data sheet. For cable section selection purposes, we suggest to add 10% to
compensate for any under-voltages that might occur in the installation.
• Use copper wires only.
• Caution
• Always double-check the fuse size versus the calculated cable size. If
required, reduce the fuse size or enlarge the cable size.
• Cable length should not exceed the maximum length according to IEC 60204
(table.10).
• Display the fuse type information next to the fuse holder of the mains branch.
• Connect the power cable with the correct cable lugs on the terminals in the
electrical cabinet.
• Do not connect more than one (1) cable lug at one side of a contactor terminal or
copper bar, unless specified otherwise.
• Respect a minimum of 10 mm IEC (1/2” CSA/UL branch circuit) between stripped
cable ends for low voltage installations.
• Fuses are maximum allowed values to protect installed compressor electrical
panel.
• 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:
• IEC: XLPE 90 °C (194 °F)
• CSA-UL: (R, RW, T) multicore 110 °C (230 °F)
• Display the fuse type information next to the fuse holder of the mains branch.
