2.6 Control and Communication Cabling 

fig.  2-6  shown,  the  Relay  card  dry  contact  interface  (J2-J10),  communication  interface  (RS232  interface,  485 

interface and SNMP card interface) and parallel card position. 

 

 

Fig 2-6 Dry contact interface and communication interface 

The UPS accepts external signal from zero-voltage (dry) contacts connected through external dry contact terminals 

produced  and  phoenix  terminals.  Through  software  programming,  these  signals  become  active  when  these  contacts 

connect  to  +24V  to  ground.The  cables  connected  to  DRY  terminal  must  be  separated  from  power  cables.  Moreover, 

these  cables  should  be  double  insulated  with  a  typical  0.5  to  1.5  mm

2

 

cross-section  area  for  a  maximum  connection 

length between 25 and 50 meters. 

2.6.1 Dry Contact Interface of Battery and Environmental Temperature Detection (Optional) 

The input dry contact J2 and J3 can detect the temperature of batteries and environment respectively, which can be 

used in environment monitoring and battery temperature compensation 1. 

J2 and J3 interfaces diagram are shown in fig 2-7, the description of interface is in table 2-2.
