Translation of the original operating instructions
CAUTION
Electrical voltage
The fan is a built-in component and features no electrically
isolating switch.
→ 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.
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).
If the use of a residual current device (RCD) is required in your
installation, only universal residual current devices (type B 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 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 of the cables
External leads are brought out of device.
;
First connect the "PE" (protective earth) connection.
●
Connect the lines according to your application. When doing so,
observe chapter 4.5 Connection screen.
4.3.1 Cable routing
No water may penetrate along the cable in the direction of the cable exit.
