3.1 Power Connection
3.1.1 Line Voltage
The matrix operates from a line voltage in the range of 110V to 240V at a
frequency of 50 or 60Hz. Line voltage selection is automatic.
CAUTION: Operating the unit on an incorrect line voltage may cause
damage, possibly voiding the warranty.
3.1.2 Line Power Connection
Perform the following steps to connect the matrix to line power:
1. Connect the female end of the supplied power cord to the
grounded AC receptacle on the rear panel.
2. Connect the other end of the supplied power cord to a grounded
AC outlet.
WARNING: The power cord supplied with the matrix contains a
separate ground for use with grounded outlets. FAILURE TO USE A
GROUNDED OUTLET MAY RESULT IN PERSONAL INJURY OR
DEATH DUE TO ELECTRIC SHOCK.
3.1.3 Line Fuse Replacement
A rear panel fuse protects the power line input of the matrix. If the line fuse
needs replacement, perform the steps below:
WARNING: Disconnect the line cord from the unit before changing
the line fuse.
1. The fuse is located in a holder in the power module unit above
the AC receptacle (figure 3-1). At top is a small tab, use a small
bladed screwdriver to release the fuse holder.
2. Slide the fuse holder out to gain access to the fuse carrier and
fuse.
3. Remove the carrier with the blown fuse, and replace with the
correct type listed in Table 3-1.
CAUTION: For continued protection against fire or unit damage,
replace the fuse only with the type and rating listed.
4. Install the fuse carrier in the fuse holder, then insert the fuse
holder back in the power entry module.
