20. 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.

21. Relay case and plug-in unit
The relay cases are assigned to a certain type of plug-in unit.
For safety reasons, the relay cases for current measuring relays
are provided with automatically operating contacts for short-
circuiting the CT secondary circuits when a relay unit is
withdrawn from its case. The relay case is further provided with
a mechanical coding system preventing the current measuring
relay units from being inserted into relay cases intended for
voltage measuring relay units.
