A. Install single phase line terminals marked AC. Connect GND line to terminal marked
GND.
B. For units marked CE, the product provides more than 3.5mA of earth leakage current.
Protective earth connection is essential before connecting the supply. An appropriate
warning marking is placed on the rear panel. (
Symbol for protective earth ground).
2.
2KW and 2.5KW:
Units are operated from a single-phase or three-phase 190-250Vac
input depending on model. Phase rotation need not be observed when connecting the
power line to the input terminal of the power supply.
A. Install the three phase line to terminals marked Phase A, Phase B and Phase C.
B. Connect the GND line to terminal marked GND.
C. Units with - CE marking are designed for a 230VAC single phase connection. Install the
input power lines to the terminals marked L1 and L2 respectively. Connect the
protective earth ground to the terminal marked
.
NOTE:
It is important that single phase power should be applied between terminals Phase
A and Phase B.
3.
5KW:
Unit is designed to operate on 190-250Vac, 342-418Vac, or 374-456Vac
three-phase input depending on the options selected when ordered.
A. Install three phase lines to terminals marked Phase A, Phase B and Phase C. Phase
rotation need not be observed.
B. Connect GND lead to terminal marked GND, or
.
C. For units with inputs of 380 Vac or higher, a Wye configuration of the input source is
required. Connect the neutral to the terminal labeled N. For inputs sources (delta) that
lack the neutral, EMI provides two transformers (EMI part numbers 28-004-890 and
28-004-952) for delta to Wye conversion. Transformer number 28-004-952 is used for
powering a single unit whereas transformer 28-004-890 can be used to power two units.
D. Units with -CE marking are designed for 400VAC Wye configuration. See above note.
