2.11.2
REPO switch port
The UPS has a REPO interface to remotely shutdown the UPS in case of an emergency (eg fire).
The function can be activated by pressing the key on the front panel of the power supply or
remotely using the remote REPO switch.
Use the J4 connector to connect the remote REPO. During normal operation, NC and + 24V
short-circuits are required. Activation of the EPO signal occurs when the NC signal is + 24V open
or short circuit of the NO and + 24V pins. The interface and connection description are shown
below.

Description
Purpose
J4.1
EPO_NC
EPO is activated when disconnected from J4.2
J4.2

24V
+24V, voltage to connect with NC
J4.3
＋
24V
+24V, voltage to connect with NO
J4.4
EPO_NO
EPO is activated when connected from J4.2
Use an external potential-free REPO circuit breaker using a normally closed (NC) or normally
open (NO) contact.
If you do not use the remote REPO, pin J4.1 must be connected to J4.2 and pin J4.3 disconnected
from J4.4.
Attention
1. Użycie wyłącznika EPO powoduje zatrzymanie pracy prostownika, falownika oraz Bypasu,
oraz odłączenie napięcia na wyjściu zasilacza.
2. Standardowo pin J4.1 i J4.2 są połączone ze sobą w momencie dostarczania sprzętu.
