FUNCTION
1
Low Batt
(Dry Contact)
Closed
when battery voltage drops below minimum.
2
Batt Discharge
(Dry Contact)
Closed
when the Internal/external batteries are discharging into
the DC Bus.
3
Fault
(Dry Contact)
Closed
when fault occurs. Generic fault warning, could mean
any of several things; DCOC (DC Over Current), DCUB (DC Unbalanced) etc.

5
Inverter
Supply
(Dry Contact)
Closed
when inverter is operating normally.
6

Supply
(Dry Contact) Closed
when inverter is operating normally. (Duplicate
terminals)
7
P24A3
24 Vdc 1 A max. source for Remote Run.
8
Remote Run*
Apply 24V to switch UPS to Inverter Mode
NOTE: The connection to the remote run inputs on terminals 7 and 8 must be
a discrete dry contact and must not be connected to other powered circuits.
Connection to other powered circuits may result in unpredictable circuit
operation or failure.
9
P24A3
24 Vdc (P24A3)
10
Remote Stop*
Apply 24Vdc to switch UPS to Static Bypass. The UPS will transfer to bypass
as soon as the input and bypass power are in sync.
NOTE: The connection to the remote stop inputs on terminals 9 and 10 must
be a discrete dry contact and must not be connected to other powered
circuits. Connection to other powered circuits may result in unpredictable
circuit operation or failure.
11
Bypass
(Dry Contact)
Closed
when UPS is in Bypass.
NOTE: Even though Remote Stop may be triggered, the UPS is not in Bypass
until Terminal 11 closes.
12
Common

EPO
(Dry Contact)
Short
across 13 and 14 will shut down all power in the UPS
including bypass and battery backup, and will cause the Battery Shunt Trip to
open the external battery breaker.
14
EPO
(Dry Contact)
Short
across 13 and 14 will shut down all power in the UPS
including bypass and battery backup, and will cause the Battery Shunt Trip to
open the external battery breaker.
