Electric connections
1. Always consult the unit's identification nameplate to verify MCA and MOP requirements.
2. Fuse is located in the main terminal board.
3. Since the indoor unit is energized from the outdoor unit and, depending upon local coding, it may be
required to install a main disconnect switch to an independent power supply for the indoor unit.
4. Install an independent disconnect for the outdoor unit. Power supply, wiring and grounding of the
equipment must comply with national, state and/or local coding. Power supply must comply with
indications located on the unit's identification nameplate.
5. Inappropriate field wiring installation and grounding leads to dangers of fire and electrocution. In the
case of high voltage connections, it is recommended to use flexible conduit when the transmission of
vibrations could create noise problems to the structure of the building. To avoid such dangers, wiring
installation and grounding requirements MUST comply with those stipulated by NEC (National Electric
Code) as well as by local and state electric codes. All field wiring must be performed by qualified and
authorized personnel. Failure to follow these requirements could lead to death or to serious injury.
6. Communication wiring between outdoor and indoor units must be of at least 14 AWG, stranded
wiring, with a maximum absolute length of 230 ft. (70m). Shorter lines could provide a more robust
communication between the indoor unit and the outdoor unit. Select the appropriate length in
accordance with the installation's actual conditions. Communication cables MUST NOT be cut or
spliced.
7. For wired controller: The communication distance between the main board and the wired controller can
be of up to 65 ft. (Standard distance is of 25 ft.)

Electric requirements
Note:
When connecting the power cable, verify that voltage, frequency and cable phase is
equatable to the voltage, frequency and phase indicated on the unit's identification nameplate.
Otherwise, the compressor will not be able to perform appropriately and therefore lead to
equipment damage.
