Connection In Terminal Box - SystemAir 35863 - AW 450 EC sileo Bedienungsanleitung

NOTE
Water ingress into wires or cables
Water ingress at the customer end of the cable can damage the
device.
→ Make sure the end of the cable is connected in a dry
environment.
Only connect the device to circuits that can be switched off with
an all-pole disconnection switch.
4.2.1 Requirements
; Check whether the data on the nameplate match 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
nameplate.
For determining the cross-section, note the sizing criteria according
to EN 61800-5-1. The protective earth must have a cross-section
equal to or greater than that of the phase conductor.
We recommend the use of 105 °C cables. Ensure that the minimum
cable cross-section is at least
AWG 26 / 0.13 mm².
Ground conductor contact resistance according to EN 61800-5-1
Compliance with the impedance specifications according to EN 61800-5-
1 for the protective earth connection circuit must be verified in the end
application.
Depending on the circumstances of installation, it may be necessary to
connect an additional protective earth conductor to the extra protective
earth terminal on the device.
The protective earth terminal is on the housing and has a ground
conductor symbol and a bore hole.
4.2.2 Reactive currents
Because of the EMC filter integrated for compliance with EMC
limits (interference emission and immunity to interference),
reactive currents can be measured in the supply line even
when the motor is at a standstill and the line voltage is switched
on.
The values are typically less than 250 mA.
●
At the same time, the effective power in this operating state
●
(operational readiness) is typically < 4 W.
4.2.3 Residual current circuit breaker (RCCB)
Only pulse-current sensitive and/or universal residual current
devices (type A or B) are permitted. As with variable
frequency drives, residual current devices cannot provide
personal safety while operating the device. When the device's
power supply is switched on, pulsed charging currents from the
capacitors in the integrated EMC filter can lead to the residual
current devices tripping without delay. We recommend the use
of residual current circuit breakers with a trip threshold of 300
mA and delayed tripping (super-resistant, characteristic K).

4.2.4 Locked-rotor protection

4.3 Connection in terminal box

4.3.1 Preparing cables for connection
Only strip the cable as far as necessary, ensuring that the cable gland is
sealed and there is no strain on the connections. For tightening torques,
see Chapter 3.1 Product drawing.
4.3.2 Connecting wires to terminals
; Remove the cap from the cable gland.
Only remove caps where cables are fed in.
; Route the wire(s) (not included in scope of delivery) into the terminal
box.
; First connect the "PE" (protective earth).
; Connect the wires to the corresponding terminals.
Use a screwdriver to do so.
When connecting, ensure that no wire ends fan out.
; Seal the terminal box.
4.3.3 Cable routing
Water must be prevented from reaching the cable gland along the cable.
Fans installed lying flat
Make sure the cable is routed in a U-shaped loop.
Due to the locked-rotor protection, the starting current (LRA) is
equal to or less than the nominal current (FLA).
NOTE
Tightness and strain relief are dependent on the cable
used.
→ This must be checked by the user.
WARNING
Live terminals and connections even with device
switched off
Electric shock
→ Wait five minutes after disconnecting the voltage at all poles
before opening the device.
