1 Mechanical Installation
1.1 Visual Check
After unpacking the frequency converter, perform a thorough visual check.
Check the following:
●The right device has been supplied
●The device has no damage
●No transport damage such as scratches, cracks or dents
If you find any deviation from one of the above points, please contact your
Bosch Rexroth sales partner.
1.2 Ambient Conditions
If it is to function perfectly, the frequency converter must be installed in an envi-
ronment matching the data provided below.
Rated ambient temperature -10...40 °C
Derating / ambient temperature 1.5 % / 1 °C (40...50 °C)
Rated altitude ≤ 1,000 m
Derating / altitude 1 % / 100 m (1,000...2,000 m)
Relative humidity ≤ 90 % (No condensation)
Degrees of protection IP 20 (Control cabinet mounting)
Degrees of pollution 2 (EN 50178)

1.3 Installation Conditions
To avoid overheating, the device must be ventilated. The recommended mini-
mum top and bottom distance between frequency converter and adjacent items
(may prevent air flow)are shown as figure below:
Fig. 1-1: Frequency converter mounting
●VFC 3210 must be vertically installed on the metal wall.
●Without heat dissipation holes on both sides of the housing, VFC
3210 can be installed side by side.
●If one frequency converter is arranged above another, make sure
the air temperature into the inlet can not exceed 40℃.
●An air guide is recommended between the frequency converters
to prevent the rising hot air being drawn into the upper frequency
converter if the upper limit of air temperature is exceeded.

2.2.2 Control Signal Connection
The following requirements are applicable to signal connection:
●Flexible cables with wire end sleeves
●Cable cross-section: 0.5...1.0 mm2
●Cable cross-section for connectors with insulation sleeves: 0.75 mm2
●Analog inputs AI, +10 V and GND: use shielded cables
●Digital inputs X1...X4, SC, +24 V and COM: use shielded cables
●Analog outputs AO and GND: use shielded cables
●RS485 communication: use shielded twisted pair cables
Recommendations on cable insulation stripping:
Please strip the insulation of control cables according to the dimensions given
below. Too long stripping may cause short circuit of adjacent cables; too short
stripping may lead to cables becoming loose.
Fig. 2-2: Cable insulation stripping length
Please follow the steps below for wiring of control terminals.
Step 1: Switch off the frequency converter before performing wiring.
Step 2: Deactivate the control signals in the wiring process.
Step 3: Switch on the frequency converter.
Step 4: Set respective parameters.
Step 5: Activate respective control signals.

As the brake resistor is not supported for VFC 3210 to connect, the
excessive energy produced in the process of braking can not be
eliminated. The outside plastic housing is not allowed to remove.

CAUTION
Please make sure that the power supply of the frequency converter has been
switched off before plugging or unplugging the connector.
Control terminals and the order are shown as the figure above. The
terminal block is ONLY for wiring convenience, which CANNOT be

Relay output terminals
When relay output terminals are connected with inductive loads (relays, contac-
tors, solenoid valves, motors, etc.), following noise suppression circuits need to
be applied at the coils of the inductive loads, as close as possible to the induc-
tive loads, in order to reduce the electromagnetic interference generated from
inductive load action.
