4.3  Cabling 

Approved  cable  conduit  and  conduit  connectors  should  be  used  to  ensure  a  safe  and  reliable 
installation. Check the local wiring code for more information. Make sure all conduit connectors 
are screwed in tight and that they are not coming in contact with any bare conductors. 
 
Strain  relief  should  be  installed  to  the  enclosure  to  prevent  any  mechanical  stress  from  being 
transmitted to terminals and internal connections. 
 
We  recommend  using  BELDEN  9841  for  communications.  This  wire  has  120  ohms  input 
impendence, which will eliminate RS-485 communication problems. 

 
QEL warrantees and support only covers installation with proper cable. If in doubt, please 
contact QEL support personnel. 
 

4.4  Connectors 

Make  sure  to  observe  wiring  to  the  correct  terminal  blocks.  Removable  terminal  blocks  are 
provided. Make sure there is no confusion about which terminal block to wire to. 

Note:  

Incorrect  wiring  to  any  of  the  terminals  of  the  Q4  Controller  could  cause 
permanent damage to the unit, which is not covered by the warranty. Incorrect 
wiring could also cause fire, electric shock, or bodily injury. Please observe the 
polarity on all connections. 

Warning:   Disconnect  the  main  supply  when  changing  any  of  the  wiring  to  the  unit.  Be 

especially  cautious  when  wiring  high  voltage  to  the  relays.  Do  not  touch 
sensitive components on the circuit card to prevent static discharge damage to 
the unit. 

4.5  Power Supply Connection 

The Q4 Controller power supply Voltage requirements are nominally 24VAC/DC.  

NOTE:  Q4

-Controller  II  has  full-wave  rectifier  and  half-wave  rectifier  circuit  on  board  for 

flexibility.

 

You will damage devices if you mix half wave and full wave rectifiers on the same AC 

source. Use extreme caution when sharing a common AC source. Sharing a common DC source 
is less problematic.

 

QEL supplies one standard transformer  

 

M-Transformer 120 to 24 VAC 200 VA [QEL SKU#: 6500-0024]
