Utility connection work
W a r n i n g
For connection of piping and wiring, contact our office, your dealer or
equipment installation company.
Connection of piping and wiring must be performed by a person who has
special knowledge and skills. If performed by an incompetent person,
leakage of water or gas, electric shock or fire may be caused.
Electric wiring work
Electric wiring works as shown below must be performed on the power distribution panel.
(the distribution board is attached to the right side plate in the case of the desk-top type)
C a u ti o n
Make sure that the electric power is disconnected from the product before
starting the wiring work.
①
Arrange the terminal block wiring for the exhaust blower in the power distribution panel as
shown in Fig.2-5. The grounding wire must be connected to the grounding terminal block. For
the power outlet and the inverter type ballast the wires go through the hole on the left side
plate, on the other hand, the wires for SW circuit board go through the hole on the right side
plate, into the frame for connection. The inverter type ballast and SW circuit board are
connected through connectors.

Connect the primary power wiring, that is rising from the floor, to each circuit breaker.
Required power supply is AC single-phase 115V or AC tree-phase 220V.
● Always connect the grounding wire properly to prevent electric shock accidents due to
ground leakage.
If there are no applicable grounding terminals in your site, the grounding work [D class
grounding work (ex. Class 3 grounding, up to 100 Ω)] should be performed. This
grounding work must be performed by an authorized electric work specialist. Contact
your dealer, us or an electric work shop, if no appropriate person is available. Operation
without grounding may cause electric shock accidents.
● Do not connect the grounding wire to gas plumbing, grounding wire of telephone, or
lighting conductor. Otherwise, fire or electric shock may be caused.
● Do not connect the grounding wire to water plumbing. The grounding may be
insufficient, if vinyl chloride piping exists.
