Selection of Electricity meter, CT, and VT
Select the electricity meter, CT, and VT by considering the following items.
(1) Install electricity meters for each refrigerant system, if circumstances allow.
(2) Select VT/CT with a small VT/CT ratio.
(3) When using an electricity meter which is specied in pulse units (kWh/pulse), usually select
a meter with a 1kWh/pulse output.
z
Outdoor unit connection interface (CN135) or touch panel controller
connection interface (TM201 CH1) to electricity meter
Item Specications Remarks
Interface Dry contact “a” contacts “a” contacts: ON when shorted *1
Pulse Speci-
cations
Width: 50ms or more
Interval: 50ms or more
Units 1kWh/pulse (pulse units) recommended
Constant Considering the electricity meters available in some
countries, use of electricity meters with 3200 pulse/kWh
(pulse constant) or less pulses are possible.
Line length restriction 492ft. (150m) or less Between Electricity meter to
Outdoor unit
Wiring specications Control and instrumentation cable CVV-S (Control-use
Vinyl insulated Vinyl sheathed cable – Shielding) *2
2-conductor 16AWG (1.25mm
2
)
Line length restriction 25m or less Between Electricity meter to
Touch panel controller
Wiring specications 2 core, twisted pair, 0.33mm2 (22AWG) *3
*1: Pulse signal: normally OFF (open), ON (closed) when shorted
*2: When aected by interference by induction, select shielded CVV cable (CVV-S cable).
This is because copper shielding tape is wrapped around CVV cable and induction
interference from adjacent power cables is alleviated and normal communication is
maintained.
In addition, when the wiring is outdoors, select weather resistance cable.
*3: Use cable in accordance with local rules for cable.
