QE81WH4W
*1. This indicates the assumed area of electric distribution to which the device is connected, the area
ranging from public distribution to factory machinery. The category II applies to the device
power-supplied from fixed facility. The surge voltage of this product is 2500 V up to the rated voltage of
300 V.
*2. The index indicates the level of conductive substance at the device’s operating environment.
Contamination level 2 means only non-conductive substance. However, occasional condensation may
lead to temporary conduction.
*3. At the connection between the secondary terminal of current sensor (k, l) and the main module terminal
(1k, 1l, 2k, 2l, 3k, 3l), use
twisted pair cable
.
*4. If stranded wire is used for current input terminals, a bar terminal must be used.
Recommended bar terminal: TGV TC-1.25-11T (Made by Nichifu)
*5. The module can be fixed easily to the base unit, using the hook on top of the module. However, if it is
used under a vibrating environment, we strongly recommend that the module be fixed with screws.
*6.
