GE LTC MAP User Manual

Connect voltage signals to the designated terminals (Voltage Input #1, #2, 

#3, #4) on the wiring and installation diagrams. Refer to Figure 3-5 for 

terminal location. 
 
NOTE: The signal specification range for Voltage Inputs #1, #2, #3, and #4 

are 0 to 300 Vrms.  If your signal input is different, contact Support Services 

as noted on back cover. 

There are two types of current inputs - powered CT and unpowered CT 

(e.g.,  Clamp On AC Current Transducer). 

Connections for unpowered CT’s are not polarity sensitive.  Connect the CT 

between the A, B, or C Current terminals (refer to Figures 3-4 and 3-5). 

Connections for powered (active) CT’s are polarity sensitive.  Refer to 

information on the active CT’s connection points for proper polarity. 

The LTC-MAP 2130 monitor collects output data from the Control Isolator at 

the digital inputs. (See Figure 3-4 for Control Isolator Input terminal 

locations.) 

NOTE: Refer to Document No. 70062MP for specific information on 

the Control Isolator, Part No. 40041MP. 

1.  Mount the Control Isolator(s) per the guidelines provided in the 

documentation provided with the Control Isolator.  

NOTE: The control Isolators are provided with a 10 foot cable; 

therefore, when selecting a mounting location, be sure it is within 10 

feet of the monitor. 

2.  Connect the output cable of the Control Isolator to the First Control 

Isolator Input  (digital channels 1-8) as designated on the wiring and 

installation diagrams. 

3.  If there is a second Control isolator installed, connect the output cable 

of the Control Isolator to the Second Control Isolator Input  (digital 

channels 9-16) as designated on the wiring and installation diagrams. 

NOTE: If only one Control Isolator is installed, it must be connected to the 

First Control Isolator input terminals on the I/O board.
