Installation
Observe the following guidelines when installing a CVM
controller:
• To minimize vibration and shock damage to the
controller, transport the controller in the original
container.
• Verify that all parts shipped with the controller.
• Do not drop the controller or subject it to physical
shock.
Parts included
• One CVM03050 controller with removable terminal
blocks (Input/Output, Power, FC, and SA terminal blocks
bus are removable)
• One installation instructions sheet
• One self-drilling No. 10 x 25 mm (1 in.) screw
Materials and special tools needed
• Small, straight-blade (1/8 in. or 3.2mm) or Phillips #2
screwdriver for securing wires in the terminal blocks
• 8 mm (5/16 in.) wrench or 10 mm (3/8 in.) 12-point
socket to tighten the square coupler bolt
• Several shims or washers to mount the CVM
• Power screwdriver, 100 mm (4 in.) extension socket,
punch, drill, and 3.5 mm (9/64 in.) drill bits to mount the
CVM
• Pliers to open and close the damper

Mounting
Observe the following guidelines when mounting a CVM
controller:
• Ensure that the mounting surface can support the CVM
and any user-supplied enclosure.
• Mount the CVM on a hard, even surface whenever
possible.
• Use shims or washers to mount the CVM securely and
evenly on the mounting surface.
• Mount the CVM in an area free of corrosive vapors
that matches the ambient conditions specified in the
Technical specifications section.
• Provide sufficient space around the CVM for cable and
wire connections and adequate ventilation through the
controller (at least 50 mm [2 in.] on the top, bottom,
sides, and front of the controllers).
• Do not mount the CVM in areas where electromagnetic
emissions from other devices or wiring can interfere
with controller communication.
• Avoid mounting the CVM on surfaces with excessive
vibration.
