Mounting methods

By means of appropriate mounting accessories, the standard

relay case can be flush mounted, semi-flush mounted or wall

mounted. The flush mounted and wall mounted relay cases can

also be mounted in a tilted position (25°) using special accessories.

Further, the relays can be mounted in any standard 19”

instrument cabinet by means of 19” mounting panels available

with cut-outs for one or two relays.Alternatively, the relays can

be mounted in 19” instrument cabinets by means of 4U

Combiflex equipment frames.

For routine testing purposes, the relay cases can be equipped

with test switches, type RTXP 18. which can be mounted side

by side with the relay cases.

When the relay is in the remote mode, it can execute

commands sent from a remote location. The relay supports the

remote selection of the local/remote mode via a binary input.

This feature facilitates, for example, the use of an external

switch at the substation to ensure that all relays are in the local

mode during maintenance work and that the circuit breakers

cannot be operated remotely from the network control center.
