Mounting
Contact Expansion Modules are delivered in sturdy cartons to prevent shipping damage. Upon receipt of
a module, check the part number against the requisition and packing list for agreement. Inspect for
damage, and if there is evidence of such, immediately file a claim with the carrier and notify the Basler
Electric regional sales office, your sales representative, or a sales representative at Basler Electric,
Highland, Illinois USA.
If the device is not installed immediately, store it in the original shipping package in a moisture- and dust-
free environment.
Contact Expansion Modules are contained in a potted plastic case and may be mounted in any
convenient position. The construction of a Contact Expansion Module is durable enough to mount directly
on a genset using ¼-inch hardware. Hardware selection should be based on any expected
shipping/transportation and operating conditions. The torque applied to the mounting hardware should not
exceed 65 in-lb (7.34 N
•m).
See Figure 202 for CEM-2020 overall dimensions. All dimensions are shown in inches with millimeters in
parenthesis.
