RPV311-TM-EN-7
The functioning of the device has been certified under the
circumstances described by the standards mentioned in
Chapter 17: Technical Specifications (item Type Tests). Usage of
the equipment in different conditions from the specified in this
manual might affect negatively its normal integrity.
The equipment shall have all their rear connectors attached
even if they are not being used, in order to keep their levels of
ingress protection as high as possible
Never manipulate liquid containers near the equipment even
when it is powered off.
Avoid modification to the wiring of panel when the system is
running.
VT circuits must never be left short circuited.
3.3
Fusing Requirements
A high rupture capacity (HRC) fuse type with a maximum
current rating of 10 Amps and a minimum dc rating of 250 V dc
may be used for the auxiliary supply (for example Red Spot type
NIT or TIA). Alternatively a miniature circuit breaker (MCB) of
type C, 10A rating, compliant with IEC 60947-1 and IEC 60947-3
may be used.
Digital input circuits should be protected by a high rupture
capacity NIT or TIA fuse with maximum rating of 10 A, or
equivalent MCB as above. For safety reasons, current
transformer circuits must never be fused. Other circuits should
be appropriately fused to protect the wire used.
Reason devices contain an internal fuse for the power supply
which is only accessed by opening the product. This does not
remove the requirement for external fusing or use of an MCB as
previously mentioned. The ratings of the internal fuses are:
RPV unit: 5 Amp, type T, 250V rating
RA units: 2 Amp, type T, 250V rating
CTs must NOT be fused since open circuiting them may produce
lethal hazardous voltages.
