Operating instructions
A3G500-AD01-58
Translation of the original operating instructions
→ Only connect the fan to circuits that can be switched off with
an all-pole separating switch.
→ When working on the fan, you must switch off the
installation/machine in which the fan is installed and secure it
from being switched on again.
CAUTION
Electric shock
Electric voltage on the metal part
→ Use the device only with the cable guard and terminal box
provided for this purpose.
NOTE
Water penetration into leads or wires
Water enters at the cable end on the customers side and can
damage the device.
→ Make sure that the cable end is connected in a dry
environment.
Connect the device only to circuits that can be switched off
using an all-pole disconnecting switch.
4.2.1 Prerequisites
;
Check that the data on the type plate match the connection data.
;
Before connecting the device, ensure that the supply voltage matches
the operating voltage of the device.
;
Only use cables designed for current according to the type plate.
For determining the cross-section, follow the basic principles in
accordance with EN 61800-5-1. The protective earth must have a
cross-section equal to or greater than the outer conductor cross-
section.
We recommend the use of 105°C cables. Ensure that the minimum
cable cross-section is at least
AWG26/0.13 mm².
Protective earth contact resistance as per EN 61800-5-1
Compliance with the resistance specifications as per EN 61800-5-1 for
the protective earth connection circuit must be verified in the application.
Depending on the installation situation, it may be necessary to connect
an additional protective earth conductor by way of the extra protective
earth terminal provided on the device. The protective earth terminal is
located on the housing and provided with a protective earth symbol and
a hole.
4.2.2 Idle current
Because of the EMC filter integrated for compliance with EMC
limits (interference emission and interference immunity), idle
currents in the mains cable can be measured even when the
motor is at a standstill and the mains voltage is switched on.
●
The values are typically in the range < 250 mA
●
At the same time, the effective power in this operating state
(operational readiness) is typically < 4 W.
4.2.3 Residual current operated device
If the use of a residual current device (RCD) is required in your
installation, only pulse current-sensitive and/or universal
residual current devices (type A or B) are permissible.
Residual current devices (RCD) cannot provide personal safety
while operating the device, as is also the case with frequency
converters. When the device power supply is switched on,
charging current pulses from the capacitors in the integrated
EMC filter can lead to the instant triggering of residual current
devices. We recommend residual current circuit breakers
(RCCB) with an activation threshold of 300 mA and delayed
tripping (super-resistant, characteristic K).
4.2.4 Basic insulation of the alarm relay
As the alarm relay only has basic insulation (for TN/TT
systems) and function insulation (for systems with external
conductor earthing) with respect to the mains voltage, and not
double insulation like the rest of the interface, corresponding
precautions must be taken for industrial applications (EN 61800-
5-1).
→ The voltage switched by the alarm relay (e.g. 24 VDC)
must then have no electrical connection to the 10 V output, 0-
10 V control input and GND (electrically isolated interface).
4.2.5 Locked-rotor protection
Due to the locked-rotor protection, the start-up current (LRA) is
equal to or less than the nominal current (FLA).
4.3 Connection in terminal box
4.3.1 Preparing connection lines for the connection
Strip the cable just enough so that the screwed cable gland is tight and
the terminals are relieved of strain. Tightening torque, see chapter 3.1
Product drawing.
NOTE
Tightness and strain relief depend on the cable used.
→ The user must check this.
4.3.2 Connecting cables with terminals
WARNING
Terminals and connections have voltage even with a
unit that is shut off
Electric shock
→ Wait five minutes after disconnecting the voltage at all poles
before opening the device.
;
Remove the cap from the screwed cable gland.
Remove the cap only in those places where cables are inserted.
