Point for attention regarding quality of the public electric power
supply
This equipment complies with respectively:

EN/IEC61000-3-11
(1)
provided that the system impedance Z
sys
is
less than or equal to Z
max
and

EN/IEC61000-3-12
(2)
provided that the short-circuit power S
sc
is
greater than or equal to the minimum S
sc
value
at the interface point between the user’s supply and the public system.
It is the responsibility of the installer or user of the equipment to
ensure. by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply with
respectively:

Z
sys
less than or equal to Z
max
and

S
sc
greater than or equal to the minimum S
sc
value.
(1) European/International Technical Standard setting the limits for
voltage changes, voltage fluctuations and flicker in public
low-voltage supply systems for equipment with rated current
≤ 75 A
(2) European/International Technical Standard setting the limits for
harmonic currents produced by equipment connected to public
low-voltage systems with input current >16 A and
≤ 75 A per
phase.
Warning, alarm, run output and operation output wiring
connections
• Connect warning, alarm, run output and operation output wiring to
the X2M terminal block and clamp as indicated by the following
diagram:
This connection is only required for the master unit.
X2M wire specifications
Note: Be sure to insulate the connecting equipment.
• Refer to the "7-1 Example of wiring entire system" on page 13 by
all means when connecting the operation output wiring.
A compressor failure may result if the operating output wiring is not
connected.
Remote switch wiring connections
• When installing a remote switch, clamp as indicated by the
following diagram:
This connection is only required for the master unit.
X3M wire specifications
Wiring connection for low noise mode
• Wiring connection for low-noise mode: clamp as indicated by the
following diagram:
This connection is only required for the master unit.
X1M (A5P) wire specifications
Wiring connection for multi-transmission
• When connecting the wiring between the master unit and the slave
unit: clamp as indicated by the following diagram:
X1M (A1P) wire specifications
CAUTION
If the multi-transmission wiring is not connected, the system will not
work and a malfunction code will be displayed.
CAUTION
• For Remote switch, use non-voltage contact for microcurrent (not
more than 1 mA, 12 V DC)
• If the remote switch will be used to start and stop the unit, set the
operating switch to “REMOTE”.
