8 Location
8.1 The RTU should be situated such that an operator has safe egress from the
substation after operation which would usually mean a location near the main door
of the substation.
8.2 Generally the Schneider T200E control unit is supplied mounted directly onto the
switchgear which is satisfactory for most installations.
8.3 The Lucy VRN2a/VRE2a is supplied with the Gemini control unit mounted directly
onto the ring main unit (RMU), above ring switch 2 cable end box. The control unit
shall be removed and either mounted onto a suitable wall in the substation or onto
the purpose-built free-standing frame (refer to 13.1Appendix C) which is supplied
with the switchgear. Note: Care shall be taken to ensure that the conduit is able to
reach the control unit from the RMU when positioning the control unit.
