Metered Power Supply Enclosure

User Manual


Chapter 1 General Information

The CTFLE Series Metered Power Supply Enclosure provides a power source for broadband cable operations. The enclosure is designed for mounting on the ground.


This Safety Guide contains important instructions that should be followed during installation and maintenance of the APC equipment and batteries. It is intended for APC customers who setup, install, relocate, or maintain APC equipment.

Changes and modifications to this unit not expressly approved by APC could void the warranty.

Failure to observe these warnings may result in serious injury, death or damage to the equipment.





Do not work alone under hazardous conditions.

Do not handle any metallic connector before the power has been disconnected.

Servicing this equipment may require working with protective covers removed and utility power connected. Use extreme caution during these procedures.

High current through conductive materials could cause severe burns.

When grounding cannot be verified, disconnect the equipment from the utility power outlet before installing or connecting to other equipment. Reconnect the power cord only after all connections are made.

Check that the power cord(s), plug(s), and sockets are in good condition.

Replacement of fuses or other parts must be with identical types and ratings. Substitution of nonidentical parts may cause safety and fire hazards.

These units are heavy. Use proper lifting techniques and equipment to avoid injury.

Chapter 2 Installation and Maintenance

Only trained service personnel should install and maintain the power supply.

Prior to installation, 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.

Do not operate the power supply where the temperature and humidity are outside the specified limits. See Specifications in this manual.


Inspect the unit upon receipt. Notify the carrier if there is damage. The packaging is recyclable; save it for reuse or dispose of it properly.

Check the package contents. The package contains the enclosure and product documentation.

CTFLE Enclosure Installation

Ensure the utility circuit breaker is OFF.

1.Set the CTFLE near the installation site.

2.Remove the screws that secure the front panels and the top section on the enclosure.

3.Unlock the bottom panel. When unlocked this panel will drop off the CTFLE easily.

4.Lift the top section off the CTFLE.

5.Remove the CTFLE floor plate and use as a template to mark the locations for the mounting stakes.

6.Remove enough topsoil so that when installed, the enclosure will sit one inch below grade.

Note: Position the stakes so that the utility and coax



cables will enter through the bottom of the enclosure.



4.Bolt the floor plate onto the stakes.

5.Set the enclosure on the floor plate and replace the bolts securing the CTFLE to the floor plate.

6.Install conduit over the utility and coax cables inside the CTFLE.


Meter Installation

1.Use the meter cabinet as a template and mark the mounting holes in the CTFLE.

Note: Mark the holes so that the meter indicator is visible through the window in the top panel.

2.Drill the holes.

3.Mount the meter in the CTFLE.

CTFLM 6009/6015 Installation

1.Insert the CTFLM into the enclosure so that the guide pins on the CTFLM and the CTFLE engage.

2.Push the CTFLM until a light “snap” is felt as the contacts lock into place.

3.Pull lightly on the CTFLM. If properly seated the CTFLM will not easily disengage.

Note: Connecting power to the CTFLM will be done in a later step.

Circuit Breaker Installation

1.Use the circuit breaker box as a template and mark the mounting holes in the CTFLE.

2.Drill the holes.

3.Mount the meter in the CTFLE.

Circuit Breaker


Utility Cable




Coax Cable


Install an approved 20 A high-magneticutility circuit breaker.

1.Refer to the diagram below for wiring details.

Connect the black and white wires from the incoming utility line.

Route the power feed coax to the bottom of the enclosure and attach to the coax cable adapter using a pin connector.

Attach the stinger lug to the pin connector center pin.

Attach suitable solid copper ground wire to the enclosure ground lug and ground in accordance with local codes.

Check for voltages between each connector pin and ground using a multimeter. Presence of voltage indicates an improper ground. If voltage is present ensure the ground contact is secure.

Reinstall the panels on the CTFLE.

Connect the CTFLM

Refer to the User Manual 990-5501packaged with the CTFLM for connecting and operating instructions.

Routine Maintenance Procedures

Visual Inspection

Check external surfaces, connectors, indicators and wiring/cable assemblies for signs of dirt, wear, and damage.


Brush dust from controls and receptacles using a small paintbrush.

Wipe surfaces with clean, dry cheesecloth.

Clean exterior surface with clean cheesecloth moistened with isopropyl alcohol or a general purpose detergent.

NOTE: Do not allow cleaning solution into the interior of the enclosure or into any connectors.

Clean electrical contacts with approved spray-typecontact cleaner.

Clean internal receptacles and circuit boards with hand controlled, dry-airjet (not more than 15 lb/in²), clean cheesecloth moistened with isopropyl alcohol. Wipe dry with clean, dry cheesecloth.
