FRAKO | Operating Manual | Power Quality Controller – PQC
Avoid direct contact with water at all cost.
– Protect the PQC against jolting and physical blows.
The instrument is installed vertically on the outside of the control cabinet or enclosure
so that the controls and display are accessible to the operator.
Hardware version V1.0: This is a Class A device. In office and residential areas, it can
cause interference to radio reception. In this case, it may be necessary to take appro-
priate precautions with the installation.
When considered from the rear, the PQC is a panel-mounted instrument with IP20
ingress protection. Adequate protection against inadvertently touching live compo-
nents must be provided, and the ingress of dust and water must be prevented by
ensuring that the instrument is installed in a suitable enclosure (e.g. control cabinet or
distribution panel).
5.1.4 Mounting the instrument
The PQC is designed for mounting in a 138 mm x 138 mm cutout to IEC 61554 in
the front of a control cabinet. It is held in place by four retaining lugs in the corners of
the instrument.
Note
The option is given of mounting the PQC in control cabinets with IP54
ingress protection. For this an additional gasket (Article No. 20-50015) is
available that seals the gap between the PQC front panel and the wall of
the control cabinet.
