Installing and Setting Up the Chassis
This section describes how to set up and install the chassis.
Before setting up the chassis, make sure these items are available:
• Chassis with application modules; the CIM is required and the DMM is optional
• Power cables; 14 or 16 gauge wire for DC power
• Contact wires for the Alarm Relays (optional)
Caution: Equipment intended only for installation in a RESTRICTED ACCESS
LOCATION accessible only to electrically skilled persons and electrically
instructed persons with the proper authorization.
Follow these steps to install the chassis:
1. Plan the installation, considering these characteristics:
• Place the chassis within 7 ft. (2.134 m) of the power source.
• Plan to use one or more of these locations for the connection to Earth Ground:
• The bonding lug on the rear of the chassis, near the bottom
• The grounding prong on the AC power cord
• The ground of the -48 VDC terminal strip
• The mounting hardware for the rack, if the rack is tied to Earth Ground
• Place the chassis adjacent to other Canoga Perkins or related equipment.
• Allow room for the cable management bracket(s) that channel the cables, allowing slack in
the cables and providing a surface for securing with a tie-wrap.
2. Unpack the chassis, cables, and modules, and inspect all parts for damage and compare them
with the packing list. Set the packaging aside in case you need to return the equipment.
3. To connect or isolate the Signal and Chassis grounds, check the location of the lug installed
between the backplane connectors for the power supplies, between slots 14 and 15. See
Figure 2.
Caution: To avoid breaking the shorting lug, screw it in only finger tight.
• To isolate the signal and chassis grounds, screw the lug into the hole with the round pad,
labeled "CH_GND/SIG_GND ISOLATED." This is the factory default.
• To connect the signal and chassis grounds, screw the lug into the hole with the square
pad, labeled "CH_GND/SIG_GND CONNECTED."
