2. Installation and wiring
CAUTION
The following information is merely a guide for proper installation.
Mitsubishi Electric Co. cannot assume responsibility for the compliance or the noncompliance to any code,
national, local or otherwise for the proper installation of this equipment.
A hazard of personal injury and/or equipment damage exists if codes are ignored during installation.
CAUTION
Ensure the safety relay unit and the FR-D700 unit is mounted closely in enclosure meeting IP54 and all
interconnection wiring is short and protected against open and short circuit faults.
Refer EN/ISO13849-2.
Installation
Mitsubishi FR-D700 safety stop function should be used under following condition and environment.
Table.1 The condition and environment for using safety stop function
Item Condition
Operation -10°C to +50°C (non-freezing) Temperature
range
Storage -20°C to +65°C
Ambient humidity 90%RH maximum (non-condensing)
Vibration 5.9m/s
2
or less
Altitude maximum 1000m above sea level
Atmosphere Indoors (without corrosive gas, flammable gas, oil mist, dust and dirt etc.)
Over voltage category II or less
Pollution degree II or less
Mounting wall mounting / vertical orientation
CAUTION
In order to meet safety stop, an approved safety relay unit to ISO13849-1/EN954-1 safety category 3 or better shall be
used in conjunction with FR-D700 as shown in example1,2.
In addition, all other components with in the safety stop loop shall be ‘safety approved’ types.
WARNING
To avoid an electric shock hazard, insert the magnetic contactor (MC) between power source and drive.
Open the contact of MC and keep away from drive for discharging time (refer to your drive’s User Manual
for information) before performing any work on the drive.
And verify that the voltage on the bus capacitors has discharged before Measure the DC bus voltage at the
P(+) and N(-) terminals or test points (refer to your drive’s User Manual for locations). The voltage must be
zero.
CAUTION
To avoid systematic faults, a test even for faulty demands of the safety function has to be performed in order to check
the correct function of the monitor signal. This test shall be carried out at system installation, any software changes,
parameterization changes, and/or at least once per year.
Refer to ‘4. Test and checking failure’.
