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 inverter 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 the equipment that is going to be connected to this
gateway is disconnected from the input power 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.

PROFIPOWER POWER ELECTRONICS

3. INSTALLATION AND CONNECTION
3.1.Installation of Profipower Gateway
The Profipower gateway of Power Electronics is a module to connect
the inverters and soft starters of Power Electronics to a PROFIBUS
network directly. It is necessary to use one gateway for each
equipment to connect it to the network.
Note: Gateway installation does not involve that the inverter or soft
starter and/or the power is configured or connected in a correct way
respectively. Make sure the peripheral installation is well done to
guarantee a correct operation of the system.
CAUTION
Motor controllers of Power Electronics operate with a high electric
energy.
Make sure the power supply has been disconnected and wait for at least
10 minutes to guarantee that DC Link voltage is discharged, before
installing the interface module of Profibus. Otherwise, you may get
personal injuries or an accident could occur.
The gateway should be installed near to the motor controller. The
maximum distance between the motor controller and the gateway
should be of 3 meters, but only if it is necessary.
