INSTALLATION
he CMN Series unit is designed for installation
in a protected environment. Units may be
installed in a 19" rack system. The system is
lightweight and can be easily moved. Some
important points to consider when positioning a unit
for operation:
∗ A properly rated (preferably dedicated) outlet is
accessible for the power cord supplied with the unit.
It is not recommended to modify the supplied cord in
any way nor should an extension cord of any kind be
used.
∗ The cord paths in the system installation should
remain clear of foot traffic or anything else that may
disturb permanent connection.
∗ The installation site should maintain an ambient air
temperature of less than 40
o
C. When the
environment for the system remains cooler during
operation, there is less stress on the batteries and
the internal electronics.
∗ The air inlets, vents and fan should not be
obstructed or blocked in any way.
∗ The air should remain free from excessive dust
and chemical fumes.
∗ The front panel is designed to fit in a standard 19"
rack. This panel fills a 5 ¼” slot. Guide Rails or
slides are recommended to support the unit's
mainframe. This system weighs in excess of 85
pounds; front panel mounting is not intended to
support the entire unit. The system has pre-tapped
aluminum slide bars available to accept some
standard slide configurations. Contact the factory
for optional slide kits and accessories if assistance
is required in properly mounting in a rack.
Once a location has been selected and the external
battery pack is connected, it is ready for operation.
Allow at least 48 hours, after the system is first
installed, to fully charge the external battery to a
maximum state. Charge time depends on the size
of batteries used.
OPTIONS
This rackmountable UPS is supplied with a matching rackmountable auxiliary battery box. This battery box is
designed to host one or two strings of batteries, to extend battery support times. The additional time is dependent
on the unit capacity and load size.
The battery pack is rated at 96VDC and comes with a mating cable that directly connects to the battery port at the
rear of the UPS. This connector is exposed, after removing the attached cover plate. The connector on the
battery and UPS are the same so that the cable can be plugged in either way. The connector used is a locking
type, when fully engaged, will not allow the cable to be pulled apart, unless the locking ears are depressed.
The battery box fits a 3 1/2” slot into a 19” rack, just like the UPS. The full depth of the battery, however, is only
23”. It is slide ready and weighs approximately 48 pounds in a single battery configuration. It weighs 85 pounds
in a dual battery configuration. An additional port is available at the rear of the battery box to add continuous
battery strings if necessary.
The battery box is designed to be upgradeable. If the single string is not adequate, the user may order an
additional string of batteries that can be easily installed in the existing box. By removing the existing mounting
screws on the existing battery, it can slide over and the additional set can now be secured, with four additional
screws, adjacent to the original set. The internal harness has an open connector provided for the second set.
After plugging this connector together, the upgrade is complete.
