The transformer converts high voltage to 240Vac. The transformer is required for powering 
the MPS48-7M from high voltage light pole applications. Use the following connection 
procedures for installing the transformer kit. 

• 

#2 Phillips screwdriver

• #1 

fl athead screwdriver (torque drive)

• Diagonal 

cutters

1.  Verify power is OFF at utility. Tag and lock 

utility power switch.

2.  Cut the plastic ties securing standard AC 

input wire kit that connects the AC input 
block to the AC input connector on the 
power module. Remove the standard wire 
kit.

3.  Locate the two countersunk holes located 

on the battery shelf. Mount the transformer 
onto the shelf using the supplied fl athead 
screws (2) and Keps nuts (2). 

4.  Connect the short red wire from the 

transformer to the L1 terminal on the AC 
input block. Torque to 4.5 in-lbs (.5 N m).

5.  Connect the short white wire from the 

transformer to the L2 terminal on the AC 
input block. Torque to 4.5 in-lbs (.5 N m).

6.  Connect the green 3-pin connector from the 

transformer to the AC input connector on 
the power module.

7.  Secure the new wiring with cable ties.

CAUTION!

Never apply high voltage to a unit without using a step-down transformer. Applying high voltage to 
the unit without the transformer will damage the unit and void the warranty.
