Installation
Connections
See Wiring Diagram 629455 (end of this section).
Make the appropriate connections as shown on the label on the
Power
Manager Xp
Transducer and on the wiring diagrams.
To prevent damaging the Power Manager deenergize (turn off) all power to the unit before you connect
or disconnect the shielded interconnecting cable and all other wiring to the terminal blocks.
!
Tightening Torque
Tighten all connection terminals to 10 in–lb maximum.
Interconnecting Cable
If a
Power Manager Xp
Display is provided be sure that its shielded cable is
connected to socket J2 on
Power Manager Xp
Transducer.
Power Supply Connections
Class 1 circuit
See CAUTION above!
Use a Class 1 power supply that is UL Listed. Connect the 0.3 amp 24 volt
dc power supply to terminal 23 (+) and terminal 24 (com) on terminal block
TB3 marked
Control Power
on the
Power Manager Xp
Transducer. Refer to
the labeling below terminal block. Use 18 AWG stranded copper wire.
To avoid possible shock, burns, or death, deenergize all electrical sources before making
any connections to the
Power Manager Xp
.
Lethal voltages can result if current transformers are open circuited while carrying
primary current. To avoid injury turn off primary circuit or short out CT secondary circuit.
CT Connections
Connect the current transformers (CTs) with 5 amp rated secondaries to the
appropriate terminals 7–14 marked
Current Inputs
on the
Power Manager Xp
Transducer. Refer to the labeling above terminal block TB2. Note the shorting
block connections on the Wiring Diagram.
See DANGER above!
Voltage Connections
Connect the system voltage (120 to 600 volts ac) to the appropriate terminals
1–6 marked
Voltage Inputs
on the
Power Manager Xp
Transducer. For system
voltages above 600 volts ac use appropriate potential transformers (PTs).
Refer to the labeling above terminal block TB1. Note the fusing
requirements (1 amp / 600 V) on the Wiring Diagram.
See DANGER above!
Transfer Switch Position
If an automatic transfer switch is used, connect an unused auxiliary contact
(Feature 14A) on the transfer switch to the appropriate terminals marked
N/E Input
on the
Power Manager Xp
Transducer terminals 13 & 14. Refer to
the labeling below terminal block TB3 (lower row). Refer to the ATS
Operator’s Manual and ATS wiring diagram for the location of Feature 14A
contact. This connection to the Power Manager allows it to monitor and
display the position of the transfer switch (page 4–1 step 1).
The transfer switch position indicating auxiliary contact (Feature 14A) must be connected to the
Power Manager for proper operation. If not, select
Other
for
Source
to be monitored (page 3–2).
