 Operation
WARNING
• When the door or cover of the pressurized enclosure is opened, use a gas detector to
check that the concentration of explosive gases in the ambient atmosphere is less than the
allowable limit.
• Before opening the door and cover of the electronics section, turn off the power and wait for
at least 25 minutes after obtaining the permission of the administrator.
• Electrostatic charge may cause an explosion hazard.
Avoid any actions that cause the generation of electrostatic charge, such as rubbing with a
dry cloth.
CAUTION
The isothermal oven is extremely hot after turning off the power immediately. Keep the protection
gas supplied for more than an hour after turning off the power. Keep hands away from the oven
components.
