UNPAcKING AND INSPEcTION - PAGE 3

Section 3: Unpacking and Inspection

The Comm/net Systems GMT and KLM 125 Series Fuse Panels were carefully packaged

at the factory to withstand the normal rigors of shipping. However, you should carefully

inspect the box and contents to conrm that no damage has occurred in transit. Most

shipping carriers require notication of shipping damage within twenty-four hours of

delivery, and it is the responsibility of the recipient to inspect the shipment immediately

upon receipt.

3.1 Package Contents

Included with your product are the following items:

yGMT 125 Fuse Panel / KLM 125 Fuse Panel

yMounting hardware kit with necessary screws and washers

Section 4: Installation

4.1 Installation Preparation

When selecting an installation location, ensure that all of the following conditions are

met before proceeding.

4.1.1 Elevated Operating Ambient Temperature

If you install the panel in a closed or multi-unit rack assembly, the operating ambient

temperature of the rack environment may be greater than room ambient. Therefore,

take care to install the equipment in an environment compatible with the maximum

ambient temperature (TMA) specied in Section 5.

4.1.2 Reduced Air Flow

Installation of the equipment in a rack should be such that the amount of air ow

required for safe operation of the equipment is not compromised.

4.1.3 Mechanical Loading

Mounting of the equipment in the rack should be such that a hazardous condition is

not achieved due to uneven mechanical loading.

4.1.4 Circuit Overloading

Give consideration to the connection of the equipment to the supply circuit and

the eect that overloading of the circuits might have on overcurrent protection and

supply wiring. Use appropriate consideration for equipment nameplate ratings when

addressing this concern.

4.1.5 Reliable Earthing

Maintain reliable earthing of rack-mounted equipment. Pay particular attention to

supply connections other than direct connections to the branch circuit (e.g., use of power

strips).

4.1.6 Disconnect Device

A readily accessible disconnect device must be incorporated in the building

installation wiring.

NOTICE

THIS PRODUCT MUST BE INSTALLED WITHIN A RESTRICTED

ACCESS LOCATION WHERE ACCESS IS THROUGH THE USE

OF A TOOL, LOCK AND KEY, OR OTHER MEANS OF SECURITY,

AND IS CONTROLLED BY THE AUTHORITY RESPONSIBLE

FOR THE LOCATION. THIS PRODUCT MUST BE INSTALLED

AND MAINTAINED ONLY BY QUALIFIED TECHNICIANS.

Step 1. Select the equipment rack location for installation of the fuse panel. Orient the

rack mount ears appropriately for either 19 in. or 23 in. rack and select either

the front-ush mount, mid-mount forward, or mid-mount rearward position to

install the mounting ears (see Figure 3).

Step 2. Attach the mounting ears with included 10-32 hardware (see Figure 4).

Depending on the attachment point selected, the panel will either be front-

ush, mid-mount forward, or mid-mount rearward in the rack.

Step 3. Secure panel to equipment rack by tightening the included 12-24 hardware

into the mounting ears (see Figure 4).

4.2.1 Lacing Bar (Connectorized Output Models Only)

Step 1. Attach the output cable lacing bar by tightening the two 10-32 pan head

screws into the threaded holes located on the rear of the panel (see Figure 5).

4.3 Chassis Ground

CAUTION

DO NOT ENERGIZE THE PANEL BEFORE

CHASSIS GROUND IS CONNECTED.

The chassis ground is located in the side of the panel. A two hole lug landing position

is provided. See table below for termination information. A minimum of #6 AWG chassis

ground cable is required.

IMPORTANT: Grounding hardware not included. A properly-sized grounding

conductor must be installed per NEC (250.122).
