4.3 Power System Assembly and Mounting
The power system must be mounted in a clean and dry environment. Sufficient free space must be provided at
the front and rear of the power system. This is to meet the cooling requirements of the rectifiers utilized in the
power system and to allow easy access to the power system components.
NOTE: The DCP03 requires at least 1RU (1.75”) of space above the unit for tooling access to the load breaker ground
connections. Ensure that at least 1RU of space is open in the relay rack above the DCP03.
4.3.1 Rack Mounted Systems
Attach the power system to the customer-provided relay rack using mounting screws and star washers to ensure
an electrical bond between system chassis and relay rack.
The system may be mounted into a 19” rack in either a flush or center mount position. 23” rack mounting (flush or
center) is accomplished via the included 19” to 23” rack adaptors.
4.3.2 Floor Mounted Systems
Secure the system to a concrete floor utilizing either heavy duty anchors (1/2” x 2-1/2”) or, for wooden floors,
heavy-duty lag screws (5/8” x 2-1/2”). Use appropriately sized flat washers.
Use isolating kits if required to isolate system from the floor.
It is recommended that the relay rack be secured to the overhead cable tray. Argus does not supply the
mechanical details necessary for overhead support.
4.4 Rectifier Module Insertion/Removal
Insert by placing the rectifier module on the shelf bottom and sliding the module into the rear connector (inside of
the shelf). Apply pressure on the module handle to engage the rear connector in the shelf receptacle.
NOTE: It is recommended that the first module be inserted into the front leftmost position using the side of the shelf (or
the optional shelf-mounted controller) as a guide. Subsequent modules may be inserted using the previous
module as a guide.
Tighten the thumbscrew (1/4-turn) latch on the bottom of the faceplate to secure the module to the shelf.
NOTE: Do not force a module into position if it does not seat properly. All modules are keyed to ensure that the correct
module (voltage/polarity) type is used.
To remove a module, loosen the thumbscrew (1/4-turn) latch on the bottom of the faceplate. Grasp handle and
pull out, sliding the module away from the rear connector and out of the shelf.
4.5 Breaker Installation
1. Ensure mid-trip breakers are used for load and series-trip breakers are used for battery connections.
2. Turn
breaker off.
3. Ensure that the breaker is right side up.
4. Align the breaker terminals with the correct holes.
5. Carefully push the breaker into position.
4.6 Breaker Removal
1. Turn breaker off.
2. Carefully pull the breaker out of position.
