2.4 Electrical Installation
With an AC power module, AC power is supplied to CH08 through a standard IEC C14 3-prong receptacle,
located on the rear of the module. Any national power cord with IEC C13 line plug may be used to connect AC
power to the power module. With a DC24 or DC48 module, DC voltage is connected to the terminal block located
on the rear of the module, observing the proper polarity.
CH08 should always be grounded through the protective
earth lead of the power cable in AC installations, or via the frame ground connection for DC installations.

2.5 Alarm Installation
The alarm relay provides one set of Power Failure contacts (normally open) and another set of FAN Failure
contacts (normally open) contacts for monitoring the power and fans condition of CH08 . The alarm contacts may
also be programmed through the management interface to react to different fault conditions.
