4.2.2 Initial commissioning procedure
After a successful test run:
Connect the fan to the supply air/exhaust air pipe sys-
tem using flexible collars (see chapter 3.3 “Inlet pipe joint
connection”).
1)
Switch on the fan using the control unit (control sta-
tion). If the fan has a repair switch, this switch must
be set to “I”. If the fan has a terminal box, all terminals
must be wired.
2)
Once operating speed has been reached, measure the
power consumption and compare it with the rated
motor current stated on the motor or fan identification
plate. Switch off immediately if continuous excess cur-
rent is measured. Check extraction mode at all available
speeds. If a motor fitted with suitable full motor pro-
tection is operated with continuous excess current, the
thermal contact/PTC thermistor switches off the motor.
3)
Check that the fan and motor are running smoothly and
not making any unusual noises. No unusual oscillations
or vibrations must be present.
4)
Lock the control unit, fan and switch cabinet, if present,
according to specifications (locking mechanism).
5)
Hand over the system according to specifications. Ex-
cess grease may leak out of the labyrinth grease filling
during initial commissioning.
5 ELECTRICAL CONNECTION
MORTAL DANGER FROM ELECTRICAL CURRENT!
The electrical installation of the fan must only be conducted
by qualified electricians in compliance with these operating
instructions and the applicable regulations:
•
VDE regulations including the
safety regulations
•
Accident prevention regulations
•
Installation instructions
5.1 Terminal connection diagrams
Only connect FUNKEN fans in line with valid terminal dia-
grams. A plan of the terminal connection diagrams can be
found on the plate on the motor cover, and at other locations.
5.2 Cable connections
Cable routing is determined by local conditions and regula-
tions. The type of cable and wire sizes are specified by the
authorised qualified electrician.
Motor protection and winding protection cables
must be routed separately to prevent interference.
Use a shielded cable for winding protection. The shielding
must be connected to the protective conductor clamp
(PE) in the control unit. The decision of whether the cable
shield must be applied on both sides can only be made on
site (e.g. due to very significant interference). In this case,
the applicable regulations must be complied with.
If on-site control units are employed, it is not necessary to
route a shielded cable as the thermal contact can be used for
230-V control voltage (up to 4 A).
After routing the cables, all cable inlets must be fitted with
splashproof seals.
5.3 Thermal contact/PTC thermistor for motor
protection
The client must ensure that the motor is equipped with
an interlock shutdown that stops the motor if the highest
permissible winding temperature is exceeded. This pre-
vents the motor from restarting after a malfunction.
5.4 Fluctuating power supply
DIN EN 60034-1 specifies a voltage tolerance of +/- 5%
(range A) for motors.
DIN IEC 60038 specifies a tolerance of +/- 10% for the mains
voltages 230 V, 400 V and 690 V.
5.5 Speed control via the frequency converter
If the device is driven by a frequency converter, there is no
need to use an all-pole sine filter between the frequency
converter and motor.
MORTAL DANGER FROM ELECTRICAL CURRENT!
Do not confuse sine filters with motor filters (often called
attenuation filters or du/dt filters).
An all-pole sine filter is the best and most reliable option
for preventing problems from arising in the first place. All-
pole sine filters produce sinusoidal output voltages: phase
