3. CONTROL VOLTAGE 

The D64RPB30 has a universal control voltage 
input, accepting nominal voltages between 24 
and 240 V DC/AC 45-450 Hz with a 
-20% / +10% tolerance. The total range of 
accepted voltages is therefore 19.2 to 264 V 
DC/AC. Power consumption is 1.5 VA maximum 
with AC voltages and 0.5 Watts maximum with 
DC voltages. 
 
Note that the built-in power supply circuit is non-
isolated. This means that there is no electrical 
isolation between the control voltage input and 
the internal electronics. As a result these share 
a common ground reference. This reference is 
applied to the system through the FB

1

 terminal 

which must be firmly connected to local frame or 
chassis ground with the shortest possible lead 
for safety and proper EMC behavior. Use a 
minimum 14 AWG stranded conductor. Control 
voltage is presented to the L+ terminal with 
respect to chassis ground. AC voltage sources 
connect their Neutral side to the chassis and 

                                                

1

 

IEC60445 defines FB as Functional equipotential 

bonding conductor. Frame bonding is the primary 
purpose of this terminal. This replaces N- designation.

  

distribute their ‘hot’ L side through wiring to the 
L+ terminals. DC voltage sources connect their 
negative - side to the chassis and distribute their 
po side through wiring to the L+ 
terminals. For good EMC behavior it is important 
(as in any installation) to run all wiring close 
along the chassis or in metal ducts, avoiding 
excess lengths. 

4. CONNECTIONS AND PRECAUTIONS 

Refer to Figure 2 for typical field connections 
 
Please consult the following checklist when 
applying the D64RPB30 
 
1.  If the D64RPB30 is used for alarming only 

purposes, or if the G/F Trip Delay is set to 1 
second or higher, verify that the D64RPB30 
cannot be subjected to conditions exceeding 
its Thermal Withstand Capability (see 
section 5: Technical Specification).
