Chapter 2 Installation and Maintenance
Only trained service personnel should install and maintain the CTFRP.
Prior to powering up the CTFRP, utility line voltage must be routed to the enclosure. Local, state,
federal and/or National Electric Code (NEC) regulations regarding location, permits and electrical
wiring must be adhered to.
Before installing the CTFRP, ensure that the input AC utility circuit breaker is OFF.
Failure to adhere to this warning may result in death, serious injury or equipment damage.
When positioning the CTFRP ensure adequate space for proper airflow. Myers recommends that
there be at least 3 inches of clearance on all sides and above the module.
Failure to adhere to this warning may result in equipment damage.

Installing the Power Supply
If already present, the AC utility circuit breaker must be OFF prior to battery installation.
1. Remove the screw holding the key to the chassis.
2. Remove the 10-32 Phillips mounting screw that secures the pole/wall bracket to the
housing.
3. Remove the mounting bracket from the housing by pulling down.
4. Set the Power Supply and the key aside.
5. Refer to Specifications in this manual for Power Supply dimensions.
6. Locate the position on the pole where the Power Supply is to be located.
7. Drill two 3/4” holes vertically spaced 6” (15.2 cm) apart.
8. Attach the top of the mounting bracket to the pole using a 5/8” pole bolt and washer. Repeat
this procedure for the bottom of the bracket.
9. Ensure that the power supply enclosure is closed and locked.
10. Holding the Power Supply above the bracket, slide the unit down the bracket. The lip of the
bracket must slide under the lip at the top of the Power Supply cabinet.
11. Replace the 10-32 Philips screw (removed in step 2 above).
Wiring
1. Unlock the CTFRP enclosure. Lift up the front cover from the bottom and flip open the top.
2. With the top flipped open, place the cover back into place and remove one of the two screws
acting as the cover hinge. The cover can now be removed.
3. Check the external AC breaker/feed to ensure that it is OFF.
4. Install a pin type connector (not furnished) to the hardline coax bushing located on the
bottom of the power supply.
5. Attach the yellow wire with the Euroblock clamp to the stinger of the pin connector.
Tighten the set-screw.

6. At the other end of that yellow wire, select the desired output voltage by moving the yellow
wire end to one of the three voltages on the terminal strip 60VAC, 75VAC or 87VAC.
Tighten all set-screws on the output voltage terminal block.
7. Secure a #6 copper ground wire into the ground lug located on the bottom of the
cabinet.Route and attach the ground wire according to local electrical codes.
8. Install an approved 20 amp high magnetic circuit breaker on the input power side of the
power supply.
