1). Operation temperature range of this unit is −10 to +40℃.
Please install this unit in a place not exposed to direct sunlight and condensation.
2). This unit has basic dustproof and drip-proof structure, but not waterproof.
Please install this unit in a place not exposed to direct water.
3). The power supplied voltage is AC85 to 264V.
Please make twist of AC wire.
4). This unit is designed to fix by wall mount.
Please make use of holes 4-Φ9.0 of attached bracket and fix with M8 bolt screw.

５－２) Connection
First remove a drip-proof cover at underneath of this unit and wire on the terminal asbelow. Terminal is 7.62mm pitch crimped terminal.
TerminalACESHLINOUT

Applicable crimp#1 #2 #3 #4#5 #6 #7 #8: Wide range of AC85 to 264V is supplied: Earth (Grounding) of AC: Shield line of current loop serial signal: Input of current loop serial signal. No polarity.
: Output of current loop serial signal. No polarity.
For connecting TOYO external equipment as cascade: Use a crimp terminal for M3 up to 6mm.

The shield line of each cable shall be grounded by either this unit or each connected
instrument, so that there is no ground loop.
Terminal #3(E) and #4(SHL) are connected inside.
