1.7.2 Instrucciones de instalación
El convertidor de frecuencia COMBIVERT de KEB cuenta con una
protección del tipo IP 20 y debe ser instalado en el interior de un
armario o un cofre. Debe además estar solidamente fi jado y bien
conectado a tierra.
– Respete las distancias mínimas (espacio libre sufi ciente)
arriba y abajo mín. 100 mm
en los lados mín. 50 mm
– Instalación vertical
– Prevea de antemano un enfriamiento sufi ciente
Si en las proximidades del COMBIVERT de KEB se encuentran
otros equipos que producen campos eléctricos o magnéticos, o
perturbaciones sobre la red de alimentación, es recomendable
situarlos lo mas alejados posible y tomar todas las medidas a fi n
de eliminar sus infl uencias.

1.7.2 Installation Instructions
The frequency inverter KEB COMBIVERT has the protective system
IP 20 and is to be installed in a casing (control cabinet). This version
of KEB COMBIVERT must be fi rmly installed and earthed.
– observe the minimum distance (free space)
– vertical installation,
– provide suffi cient cooling
If other consumers which produce electric or magnetic fi elds or
which effect the power supply are located in the vicinity of the
KEB COMBIVERT, they must be positioned as far away as possible
from the frequency inverter and steps must be taken to suppress
any interference.
