Precautions when installing the Equipment
8. Never operate in an atmosphere where flammable or explosive gas is present.
Never operate this Equipment in an atmosphere where flammable or explosive gas is present.
This Equipment is not explosion-proof. Spark may be discharged by switching Earth Leakage
Breaker (ELB) “ON(
|
)” and “OFF(○)” and also relay during operation, and then it may cause
fire or explosion.
See Chapter 13. “List of Dangerous Substances” for flammable and explosive gases on
page .76
9. Connect Power Cord/Power Cable to receptacle or switch board of facilities.
Connect Power Cord/Power Cable to suitable receptacle/switch board of facilities according to
electrical requirements as follows.
Electrical
requirements:
DNF811
AC220V single phase 50/60Hz 15.5A or more
(
ELB capacity
;
20A
)
DNF911
AC220V single phase 50/60Hz 18.5A or more
(
ELB capacity
;
20A
)
The operational voltage range is ±10%, the voltage range where the specified performance is
guaranteed is rating±5%, the frequency is rating±1%.
※
Check line voltage of its receptacle/switch board of facilities and/or whether utilize the same
line with other equipments or not, if this Equipment does not start up/operate even to turn
Earth Leakage Breaker(ELB) On(
|
). Take correct action for the solution, such as changing its
power source away from other equipment.
10. Must connect grounding wire properly.
・
Must connect grounding wire properly to grounding line or terminal in order to avoid electrical
shock due to electrical leakage.
・
Never connect grounding wire to gas line pipe or water line pipe due to fire or electrical
shock.
・
Never connect grounding wire to telephone grounding line or to lightening conductor due to
fire or electrical shock.
・
Require to ground by Electrical Equipment Technical Standards Section 19-calss
D(Grounding Resistance Max. 100Ω) in Japan, if grounding terminal is not provided. Please
contact with local dealer, local electrician, or Yamato Customer Service Center.
・
Connect the terminals firmly to switch board of facilities or appropriate power plug.
・
Power plug itself will not be included as an accessory of this Equipment. Connect to the
power supply facilities that meet the electric capacity.
