External contact signal terminal block
(FIGURE 1.6)
-
Terminal block to connect contact
signal input/output lines to and from the external devices. Refer to Figure 2.15, Section 2.4
for details.
4.
RS232C communication connector
(FIGURE 1.6)
-
Refer to Figure 2.18 Section 2.5 for
details.
5.
Inverter start switch -
This switch is used to transfer the UPS from static bypass to
inverter during maintenance purposes. Transfers will lock-out if the bypass voltage is
more than +12%,-12% of nominal.
* Uninterrupted switching is made at the time of synchronous operation. Switching is impossible at the
time of asynchronous operation.
6.
“INVERTER STOP” switch
- This switch is used to transfer the UPS from inverter to
static bypass during maintenance purposes. Do not operate it under normal operation.
Transfers will lock-out if the bypass voltage is more than +12%,-12% of nominal.
* Uninterrupted switching is made at the time of synchronous operation. Switching is impossible at the
time of asynchronous operation.
7.
“FAULT RESET” switch (FOR SERVICE PERSONNEL ONLY) -
This switch resets errors
resulting from alarm conditions. (Do not operate this switch while inverter and converter
are in operation.)
8.
Maintenance (Set) button (FOR SERVICE PERSONNEL ONLY) -
This switch sets the
UPS menu parameters.
9.
“Test mode” switch (FOR SERVICE PERSONNEL ONLY) -
This switch changes system
operation to the test-mode. (This switch should not be operated by personnel other than
an Authorized Service Engineer).
10. “BOOT” switch
(FOR SERVICE PERSONNEL ONLY)
- This switch reloads firmware to
the main board. (Do not operate this switch while inverter and converter are in operation).
