4.5.1.1 - INSTALLATION PROCEDURE: INPUT VOLTAGE 120VAC OR 277VAC, OUTPUT VOLTAGE 120/208/220/230/240/277VAC.
If the input voltage is 120V/277V, then the input cables are connected to the input terminals of bottom transformer
cabinet (11b in Fig.20). For external battery pack installation please proceed with section 4.5.5.
If 2 parallel operating units will be installed, please proceed with section 4.5.6.
1. Mount the levelers as shown in Fig.6a.
2. Loosen the screws and remove the metal access cover (20 in
Fig.20) to get access to the breakers.
3. Loosen the screws and remove the conduit boxes (17 in
Fig.20) and the cover plate (11 in Fig.19).
4. Make sure that all circuit breakers (7,8,9 in Fig.19) are in ‘off’
position (down). Please refer to fig. 7, step 4.
5. Input/output connection:
Lead the input/output cables through the cable inlet. If the
cables come from below (recommended for 10kVA models),
you can rotate the cable inlet 90 degrees. Connect the input
wires to the input terminals (11b in Fig.20). Connect the output
wires to the output terminals (11a in Fig.19). Please refer to
section 4.5.2.1 (input) and 4.5.3 (output) for detailed
information.
6. Re-install the cover plate (11 in Fig.19), conduit boxes (17 in
Fig.20) and access cover (20 in Fig.20).
7. An emergency shutdown switch can be connected to
connector J3 on the RS232/Contact Interface Card, between
pins 3 and 4. See section 6.2 for more information.
8. For advanced communication possibilities, the RS232/contact
interface port (12a) can be connected to a computer system.
See section 6.1 for more information.
9. The middle ‘option slot’ (13 in Fig.19) allows easy installation of
plug-in cards: SNMP Card or Relay Card. See sections 6.3 and
6.4 for more information.
10. The right ‘option slot’ (14 in Fig.19) allows easy installation of
the RPA-card (Redundant Parallel Architecture). If the card is
already mounted, and if the unit is used as stand-alone, a bus
terminator (delivered with the unit) has to be placed in one of
the two bus connectors on the card. If the unit will be part of a
parallel system, see sections 4.5.6 and 7.3 for more
information.
11. Connect the utility power to the UPS.
12. If hardware modifications were necessary in step 5 because
the output voltage is different from the default (277Vac),
software modifications should be performed as well. Proceed
with 4.5.4.
13. For a quick start proceed with section 5.2 ‘Start-up’.
