4. Mounting
RE_ 610 can be:
*
Flush mounted
*
Semi-flush mounted
*
Semi-flush mounted in a 25º angle
*
Rack mounted
*
Wall mounted
*
Mounted to a 19" equipment frame
*
Mounted with a RTXP 18 test switch to a 19" rack
You need separate mounting kits for the different methods except for the
flush-mounting method. This section also includes instructions on how to
install the optional lens sensors for an arc protection system (REF 610 only).
The relay’s construction with a detachable plug-in unit allows an easy
installation. Before mounting the relay, detach the plug-in unit from the relay
case.
4.1. Detaching and installing the plug-in unit
Before detaching the plug-in unit from the case, the auxiliary
voltage must be disconnected.
To detach the plug-in unit:
1. Lift the lower handle until the spring-loaded locks on both sides of the
handle are released and the unit is pushed about 6 mm out of the case. This
separates the connectors.
2. Pull the unit out of the case.
The relay features an automatic short-circuit mechanism in the current
transformer (CT) connector. Therefore, detaching the plug-in unit will not
open the secondary circuit of the CT which otherwise could cause
dangerously high voltages.
Signal connectors are left open when the plug-in unit is detached.
