Echelon SmartServer 2.2 Hardware - Manual (Page 19)

!
Safety Warning
The SmartServer uses a Poly-carbonmonoflouride Lithium Coin battery. THERE IS A
RISK OF EXPLOSION IF THE BATTERY IS REPLACED BY AN INCORRECT
TYPE. DISPOSE OF UNUSED BATTERIES ACCORDING TO THE
INSTRUCTIONS.
!
Safety Warning
The SmartServer is not equipped with a power disconnect device. When the device is
installed and mounted, the installer must provide a means to safely remove power, such
as a power switch or a circuit breaker.
!
Safety Warning
The high-voltage terminal block has a plastic cover protecting the screw terminals used to
connect the high-voltage inputs. This cover MUST be replaced after the power wires are
connected and before the power is activated.
The SmartServer is powered by a 100/240VAC, -6% to +10%, 50/60Hz VAC power mains
connection. This connection is also used for L
ON W ORKS network communication for the PL-20 with
internal coupling model of the SmartServer. The SmartServer contains an auto-ranging, auto-setting
mains power supply. You do not need to adjust any jumpers or other settings when connecting the
SmartServer to the AC power mains.
The high-voltage connection is implemented on screw terminals 1 (Earth Ground), 3 (Neutral), and 4
(Line). Screw terminal 2 (NC) is not used, and must remain unconnected. A solid earth ground via the
terminal 1 connection is required for proper ESD and EMC performance of the SmartServer device.
Connect the screw terminals for the high-voltage models of the SmartServer in the following order:
1. Insert the earth ground connection.
2. Insert the neutral connection.
3. Insert the line connection.
DO NOT apply power to the SmartServer until you have checked all wiring connections.
The following figure illustrates the location of the high-voltage AC power mains screw terminals on
the SmartServer.
