voltage llucruations and flicker in public low-voltage supply sys-
tems for equipment with rated current ≤ 75A
(2) European/International Technical Standard setting the limits for
harmonic currents produced by equipment connected to public
low-voltage systems with input current > 16A and ≤ 75A per
phase.
Warning, alarm, and operation output wiring connections
• Connect warning, alarm, and operation output wiring to the X2M
terminal block and clamp as indicated by the following diagram:

CAUTION
• Refer to the "7-1 Example of Wiring Entire System" by all means
when connecting the operation output wiring.
A compressor failure may result if the operating output wiring is
not connected.

CAUTION
• For Remote switch, use non-voltage contact for microcurrent (not
more than 1mA, 12VDC)
• If the remote operating switch will be used to start and stop the
unit, set the operating switch to "REMOTE".
〈Precautions for Terminal Connections〉
• Be sure to use ring-type crimp-style terminals provided with insu-
lation sleeves.
• Use specified electric wires for the wiring and secure the wiring so
that external force will not be imposed on the terminal block.
Crimp-style terminal
• Use an appropriate screwdriver to tighten the terminal screws.
Small-sized screwdriver will damage the screw heads and cannot
tighten the screws properly.
• Do not tighten the terminal screws in excess, otherwise the
screws may be damaged.
• Refer to the following table for the tightening torque values of the
terminal screws.
• Take out the earth wire from the notch of the cup washer and lay
the wire carefully so that other wires will not be caught by the
washer. Otherwise, the earth wire may not contact sufficiently and
the earthing effect of the wire may be lost.
• Do not finish strand wire with solder.

7-4 Procedure for Wiring Inside Units

• Referring to the following figure, secure and wire the power and
transmission wiring using the accessory clamp (1), (2), and (3).
• Lay the ground wire so that it will not come in contact with the lead
wires of the compressor. Other equipment will be adversely
affected if the ground wire comes in contact with the lead wires of
the compressor.
• Make sure all wiring do not contact to the pipes (hatching parts in
the figure).
• The transmission wiring must be at least 50 mm away from the
power wiring.
• After wiring work is completed, check to make sure there are no
loose connections among the electrical parts in the control box.
