Any online modifications to parameters done prior to restoring a configuration that were not committed to the device are lost, if those parameters are in the stored
configuration.
Serious injury or death may result from explosions. Before making electrical connections to an Intrinsically Safe model at the HART
®
jacks, verify the HART
®
instrument of interest is installed in accordance with intrinsically safe field wiring practices.
Note: Restrictions apply to the use of Intrinsically Safe units in hazardous areas. Refer to the Intrinsic Safety Control Drawing in the Instruction Manual IM 01R01A30-01EN
Yokogawa reserves the right to revise the Intrinsic Safety Control Drawing
in the Instruction Manual
IM 01R01A30-01EN without notice.
Contact Yokogawa (phone 800.888.6400) for the current Intrinsic Safety Control Drawing.
For Intrinsically Safe model YHC5150X, consult the Intrinsic Safety Control Drawing in the Instruction Manual IM 01R01A30-01EN for restrictions, for special instructions in use, and
for electrical connections allowed.
For Intrinsically Safe model YHC5150X, verify the instruments in the loop are installed in accordance with intrinsically safe field wiring practices before making
connection from the field device to the Unit’s loop communication jack. See the Hazardous Area Use Section of this manual and the Intrinsic Safety Control
Drawing in the Instruction Manual IM 01R01A30-01EN.
Note the following WARNINGS and REQUIREMENTS for YHC5150X models
:
•
Substitution of components may impair Intrinsic Safety
•
To prevent ignition of flammable or explosive atmospheres;
Disconnect power before servicing
Do not use battery charger in a hazardous atmosphere.
DO NOT
attempt to open the battery pack and replace the batteries.
SAFETY NOTICES
If an electric shock is felt when touching the charger or YHC5150X docked in the charger, unplug charger immediately from outlet. Remove the YHC5150X
from the charger immediately after you determine it is safe.
If there is any deformation, cracks or other damage to the charger base, power cord, or power adapter, unplug the charger and discontinue use.
Do not disassemble or modify any component. This could cause failure or injury, invalidate certification and void the warranty.
Plug power adapter directly into an outlet. Do not use power adapter with an extension cord.
Do not subject the batteries to intense heat. This could cause overheating, fire, rupture or explosion.
