Where to Mount the Rack
Sensor3 dimmer racks require 25 cm of top clearance for proper
airflow through the cabinet. To allow the door to open
sufficiently to install and remove modules, install the rack with
41 cm of front clearance and 15 cm clearance to the left of the
door hinge from walls or other equipment.
Note:
Dimmer Room Requirements
• A main circuit breaker cabinet or other readily accessible
input power disconnect device.
• A clean (not dusty) temperature-controlled environment
• Restricted public access to prevent tampering
• Soundproofing or performance area separation to muffle
ventilation fan noise

36, for environmental details.
ESR3-12 racks are normally wall-mounted. ESR3-24 racks can be
wall or pedestal mounted. ESR3-36 and ESR3-48 racks are
designed to be free standing.
Install racks with the CEM3 about 100 cm from the floor. In
ESR3-12 and ESR3-24 racks, the CEM3 is in the bottom slot. In ESR3-36 and ESR3-48 racks, the CEM3
slot is in the middle.
Wire Routing
Sensor3 racks have access panels at the top and bottom, and conduit knockouts at the side. Line and
load wiring can enter from the top or bottom. Control cables can enter from the top, bottom or side.
Signal and power wiring must be run in separate conduits.

Additional Sensor3 racks of the same size are the
single exception to the 15 cm left clearance rule.
They can be installed side by side without
problems.
