Safety Precautions

WARNING
!
Cover the terminal blocks with the Terminal Block Protection Covers.
Uncovered terminal blocks can result in electric shock.
! WARNING
Use DC power supplies with safe extra low-voltage circuits on the
secondary side for the main F400 power supply and power supplies for
the terminal blocks. Excessively high voltages can result in electric
shock.
! Caution
Do not touch fluorescent or halogen lights while the power is ON or
immediately after the power is turned OFF. These lights generate heat
and can cause burns.
! Caution
Do not use the F400 in environments with flammable or explosive gases.
! Caution
Install the F400 away from high-voltage equipment or motors to ensure safety during
operation and maintenance.
! Caution
Use the power supply cables and crimp terminals of specified sizes.
! Caution
Turn ON the power supply after confirming the wiring.
! Caution
Use at the power supply voltages specified in this manual.
! Caution
Be sure to securely tighten the screws when mounting F400 components.
! Caution
Do not dismantle, repair or modify any F400 components.
! Caution
Dispose of F400 components as industrial waste.
Caution
!
To prevent damage from static electricity, use a wrist strap or another device for pre-
venting electrostatic charges when touching terminals or connector signal lines.
! Caution
Do not turn OFF the power while a message is being displayed indicating that proces-
sing is being performed. Data in memory will be destroyed, and the F400 may not
operate correctly the next time it is started.
