Installation and safety instructions
for AC/DC built-in devices
Prerequisites
– Check that the data on the rating plate correspond to the connection data.
– Before connecting the device, make sure the power supply matches the
device voltage.
– Only use cables designed for the current level indicated on the rating plate.
Connect wires to terminals (only applies to devices with terminal connection).
WARNING
Terminals and connections may be live even with the device
switched off
Electric shock
Wait five minutes following all-pole disconnection of the
voltage before touching the device.
WARNING
Voltage at cable gland
Electric shock
Never use metal cable glands for plastic terminal boxes.
Residual current circuit breakers
It is strongly recommended to make exclusive use of universal
residual current devices (type B or B+). As is also the case with
frequency converters, the use of residual current devices of type
A does not provide protection for personnel during operation of
the device.
When the device power supply is switched on, charging current
pulses from the capacitors in the integrated EMC filter may cause
residual current devices to be instantly tripped. We recommend
the use of residual current circuit breakers with an activation
threshold of 300 mA and delayed tripping (super-resistant,
characteristic K).
Reactive currents
On account of the integrated EMC filter fitted to ensure compli-
ance with the EMC limits (interference emission and immunity),
reactive currents can be measured in the mains line even with
the motor not running and mains power switched on.

Plug connection
3.3.1.
Preparation of cable for connection
The cables, including the customer interface, are subject to the
specifications for internal wiring.
Ensure conformity with applicable standards and check the type
of protection in the end device after installing the ebm-papst
device.
3.3.2.
Making supply connections
WARNING
Voltage
The device is a built-in component with no isolating switch.
Connect the device to a suitable tripping device.
Only connect the device to circuits which can be de-energised
with an all-pole disconnection switch.
When working on the device, the system/machine in which
the device is installed must be secured so as to prevent renewed
switch-on.

Never reach into the opening - risk of injury. The protective
earth must be connected.
Caution - metallic parts may be live: Interrupt the power
supply.
Protection for the fan/motor must be provided in the device by
way of a fuse, thermal cut-out, overcurrent release or similar.
In accordance with DIN EN 60335-1, a fuse with a rating of
max. 16 A must be fitted in the supply line to protect the device.
– Check the pin assignment of your connector.
– Plug the built-in connector and mating connector together.
– Make sure the connector is properly engaged.
3.4.
Checking connections
– Ensure isolation from the supply (all phases). Secure against renewed
switch-on.
– Check that the mating connector is properly engaged in the built-in con-
nector.
– Check that the mating connector is properly attached to the connecting
cable.
3.5.
General – switching on device
WARNING
Hot housing
Risk of fire
Make sure there are no combustible and flammable sub-
stances in the vicinity of the device.
– Before switching on, check the device for any obvious external damage
and make sure the safety devices are functioning properly.
– Apply the nominal supply voltage.
– Start the device by altering the input signal.
– Check the air flow paths of the device for foreign matter and remove any
foreign matter found.
– Apply 0 VDC to the 0-10 V control input if this is being used.
– Apply 0 % PWM to the PWM control input if this is being used.
3.6.
General – switching off device
– Device switch-off during operation:
– Switch off the device by way of the control input.
– Do not switch the motor on and off at the mains (e.g. in cyclical operation).
– Device switch-off for maintenance:
– Switch off the device by way of the control input.
– Disconnect the device from the power supply.
– On disconnection, make sure the earth conductor connection is discon-
nected last.
