SATEC PM180 Installation Manual - Manual (Page 7)

PM180 Substation Automation Unit 4
2.2 Electrical Installation
The PM180 is packed without battery; therefore it must be installed by the
installer during the PM180 installation (see chapter 4. Installing the Battery).
After turning "ON" the PM180 power supply for the first time following battery
installation, the PM180 initialization process duration may take about 7 minutes,
while regular PM180 initialization process duration takes 40 seconds
2.2.1 Power Source Connection
The PM180 unit has two independent power supplies: main and auxiliary backup power supply. The standard
power supply may be connected to a 50-290V AC or 90-290V DC power source. Lower voltage DC power supply
options are also available (see Appendix: Technical Specifications).
The main power supply connections are:
• AC power: line to VOLTAGES board terminal "L/+"; neutral to VOLTAGES board terminal "N/−".
• DC power: positive to VOLTAGES board terminal "L/+"; negative to VOLTAGES board terminal "N/−".
The auxiliary backup power supply connections:
• AC power: line to AUX. P.S. AC/DC board terminal "L/+"; neutral to AUX. P.S. AC/DC board terminal
"N/−"
• DC power: positive to AUX. P.S. AC/DC board terminal "L/+"; negative to AUX. P.S. AC/DC board
terminal "N/−".
Copper wiring 1.5-2.5 mm 2 (15 -13 AWG) should be used.
2.2.2 Current Inputs
PM180 has 4 current inputs up to 50A with internal current transformer and up to 100A with external SATEC split
core CT – HACS 100A, connected to Relay Protection CT’s via CURRENTS board terminal. Copper wiring 2.5 – 6
mm
2
(10 AWG) should be used.
2.2.3 Ground
Connect the chassis ground of the PM180 to the switchgear earth ground using dedicated wire greater than 2
mm
2 /14 AWG.
2.2.4 Voltage Inputs
PM180 models have 3 AC Y-connected voltage inputs of 690V (phase-to-phase) and neutral, and one separate
isolated AC/DC voltage input of 400V.
2.2.5 Wiring Configurations
Use any of the seven wiring configurations shown in Figures 2-3, 2-4, 2-5a/5b, 2-6, 2-7, 2-8 or 2-9.
