rack assembly, the operating ambient temperature of the rack must not exceed the
maximum rated temperature for the chassis used.
Installation of the equipment should be such that the air flow in the front and back
of the unit is not compromised or restricted.
Installing this equipment into a rack in such a way as to make it unstable may cause
injury or death. Always make sure that the rack you are installing this equipment
into is properly secured, stable, balanced and designed to carry the weight and
weight distribution of this equipment.
Never use this equipment to carry any weight except its own. Never use it as a
shelf to support the weight of other equipment.
Installing Modules
Modules are installed in the chassis by attaching the L shaped bracket to the bottom
of the module.
The side of the bracket with two holes will be installed on the module by removing
the screws from the module and using them to attached the bracket to the module.
The side of the bracket with one hole will be installed on the chassis using the
included screw.
L Shaped Bracket for Mount Modules to Chassis
Save the unused brackets in a safe place or secure them to unused chassis
openings.
DC Powered Chassis Preparation and Cabling
This chassis is intended for installation in restricted access areas. ("Les matériels
sont destinés à être installés dans des EMPLACEMENTS À ACCÈS RESTREINT").
A restricted access area can be accessed only through the use of a special key, or
other means of security.
The over current protection for connection with centralized DC shall be provided in
the building installation, and shall be a UL listed circuit breaker rated 20 Amps, and
installed per the National Electrical Code, ANSI/NFPA-70.
The DC Power Supplies require 38-60VDC/3.0 Amps power.
Appropriate overloading protection should be provided on all DC power source
outlets utilized.
WARNING: Only a DC power source that complies with
safety extra low voltage (SELV) requirements can be
connected to the DC-input power supply.

WARNING REGARDING EARTHING GROUND:
o
This equipment shall be connected to the DC supply
system earthing electrode conductor or to a bonding
jumper from an earthing terminal bar or bus to which the
DC supply system earthing electrode is connected.
o
This equipment shall be located in the same immediate
area (such as adjacent cabinets) as any other equipment
that has a connection between the earthed conductor of
the same DC supply circuit and the earthing conductor,
and also the point of earthing of the DC system. The DC
system shall not be earthed elsewhere.
o
The DC supply source is to be located within the same
premises as this equipment.
o
There shall be no switching or disconnecting devices in
the earthed circuit conductor between the DC source and
the earthing electrode conductor.
14-Module Chassis with Two Installed DC Power Supplies
Insure that both FlexPoint Chassis power supplies are properly attached to the
chassis using the mount screws and guide pins.
Insure that both FlexPoint Chassis power supply switches are in the OFF position.
Locate the DC circuit breaker and switch the circuit breaker to the OFF position.
Prepare a power cable using a three conductor insulated wire (not supplied) with
12AWG to 14AWG thickness. Cut the power cable to the length required.
Strip approximately 3/8 of an inch of insulation from the power cable wires.
Connect the ground wire to the ground terminal on the chassis by fastening the
stripped end to the DC power connector (ground).
Connect the power cables to the chassis by fastening the stripped ends to the DC
power connector.
WARNING: Note the wire colors used in making the positive, negative and ground
connections. Use the same color assignment for the connection at the circuit breaker.
Connect the power wires to the circuit breaker and switch the circuit breaker ON.
Turn both FlexPoint Chassis power supply switches on and check the power LED's
on the front panel of the powered chassis. The two LED's should be ON.
The power supplies are hot swappable and can be replaced without shutting the
chassis down. However, when removing and replacing a power supply, the following
