Grounding and Power Connections
Ensure to ground.
This product uses a line filter. If the product is not grounded, an electric shock might occur.
Ensure to connect the protective conductor terminal of the power input terminal of this product
to an earth ground so that ground resistance is 100
Ω
or less. If the product is not certainly
grounded, an electric shock might occur.
For grounding, use the supplied power cable or an equivalent cable whose diameter is same or
greater (see Table 2-5).
Before connecting the product to power source, check the followings.
The power supply for this product must be taken from the distribution board.
Before connecting this product to the distribution board, be sure to cut the power to the
distribution board. Otherwise, an electric shock might occur.
Route the wire so that the distance between this product and the distribution board switch
(breaker) is 3 m or less. If the distance with the distribution board exceeds 3 m, install another
switch within 3 m from this product to connect. Use a switch that can cut the power from both L
and N (excluding protective grounding).
Condensation may form inside the product when the ambient temperature or humidity changes
suddenly, for example, after transportation in winter. In such case, leave the product in room
temperature enough time to evaporate the condensation, and then connect the product to the
power source.
Check the power source
For safety, use the product in the ranges of input voltage and frequency described below. Connect
the product to a distribution board which provides the power sufficiently higher than the maximum
input power of each model (see Table 2-5). For the models of which rated output is 6 kVA or more,
if the power input voltage is 170 V or less, the maximum output active power is restricted by the
wattage limiter function of this product. For details, see
Voltage range: Single-phase 100 to 230 V
Frequency range: 50 Hz/60 Hz
