4.1 Mechanical Installation
D Selecting the Installation Site
Maintain an ambient temperature of 0 to 50 _C. Don’t forget to allow for other heat sources
in the vicinity. Remember that if instruments are stacked on top of each other with little or no
gap between them, additional heat will be generated. The front and rear of the controller
should have good accessibility.
4.1.1 Work prior to installation
The controller type 6DR2100-5 is set to 230 V AC mains voltage in the as-delivered state. The
switching contacts are locked. The backplane module must be removed to change the mains
voltage setting or to unlock the relay contacts.
D Removing the backplane module
!
CAUTION
The backplane module may only be removed when the mains plug and the
3-pin ±Δy-plug have been removed!
Loosen the fastening screw (6) and pull the module out from the back.
