SAFETY INSTRUCTIONS
IMPORTANT!
Safety instructions showed in this manual are useful to teach user
how to use the product in a correct and safety way with the purpose
of preventing possible personal injuries or property damages.
Safety messages included here are classified as it follows:
WARNING
Do not remove the cover while the power is applied or the unit is in
operation.
Otherwise, electric shock could occur.
Do not run the braking unit with the front cover removed.
Otherwise, you may get an electric shock due to the high voltage terminals
or exposure of charged capacitors.
Do not remove the cover except for periodic inspections or wiring,
even if the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
Wiring and periodic inspections should be performed at least 10
minutes after disconnecting the input power of the equipment which
is going to be connected with this braking unit and after checking the
DC Link voltage is discharged with a meter (below 30VDC).
Otherwise, you may get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use cables with damaged insulation.
Otherwise, you may get an electric shock.
Do not subject the cables to the abrasions, excessive stress, heavy
loads or pinching.
Otherwise, you may get an electric shock.

DB SERIES POWER ELECTRONICS
CAUTION
Install the braking unit on a non-flammable surface. Do not place
flammable material nearby.
Otherwise, fire could occur.
Disconnect the input power if the drive or the braking unit gets
damaged.
Otherwise, it could result in a secondary accident or fire.
Do not connect the braking resistor directly to the DC terminal (P/B1,
N) of the braking unit.
Otherwise, fire could occur.
Do not touch the braking unit, drive and the resistor right after the
power is turn off.
The resistor is still hot.
Do not apply power to a damaged drive or braking unit, or to a drive
or braking unit with parts missing even if the installation is
complete.
Otherwise, fire or accident could occur.
Do not allow lint, paper, wood chips, dust, metallic chips or other
foreign matter into the braking unit.
Otherwise, fire or accident could occur.
