Use sheathed vinyl cord or wire.
Wire type ......... Wire should not be lighter than ordinary PVC sheathed flexible cord IEC 60227
(designation 60227 IEC 53)
Wire size ......... 0.75mm
Use the sheathed vinyl cord or wire.
Wire type ......... CPEVS, CVVS or equivalent"
Wire size ......... Solid wire : ø1.2mm to ø1.6mm
Twist type : 1.25mm
Use the wire which is recommended by Echelon Corporation.
For details, refer to "FT3120/FT3150 Smart Transceiver Data Book".
For reference, Cable Types and Typical Parameters.
Cable type
Belden 85102, single twisted pair,
standed 19/29, unshielded, 150˚C
Belden 8471, single twisted pair,
standed 19/29, unshielded, 60˚C
Level IV 22AWG, twisted pair,
typically solid & unshielded
JY(St) Y 2X2X0.8, 4-wire herical twist,
solid, shielded
TIA568A category 5 24AWG, twisted pair
If a shielded cable is used, the shield should be connected to earth ground via a single 470kΩ,
1/4 W, ≤10%, metal film resistor to prevent static charge build-up.
To install the main body, prepare four M4 screws which are suitable for the installation area.
Breaker for wiring
3A
Use a breaker with a contact distance of 3mm or more.
