D4 Rack-Mount Driver
Rack-mounted D4 drivers require a 19-inch equipment rack. Each D4 driver requires one unit
(1U) of rack space.
Note:
Install this device in a location with restricted access where only qualified
personnel and service persons can gain access with the use of a key. If this equipment is
installed in a location without restricted access, the wiring area of the rack should only
be accessible with the use of a tool.
D4 Wall-Mount Driver
Wall-mounted D4 drivers require 7.6 cm (3 in) clearance around the side vents for proper
ventilation.
D4 Constant Voltage Drivers and Voltage Drop
Consult the manufacturer's documentation for your load to find the minimum voltage required
for operation. Voltage drop calculations vary by project and are based on the type, length, and
gauge of wire used between the D4 Driver and load. Contact a qualified electrician or ETC
technical services for further information.
