Installation:  
A. Mounting  
1. Decide on a location to install the unit, away from moisture, high humidity, heat sources, etc.  
2. Make sure there is enough space around the unit so air can flow in and out for cooling  
purposes.  
3. Be sure ventilation holes are not blocked by other equipment, rack housing, walls, etc.  
4. To avoid undesirable operation in either the product or other equipment place the unit at  
least 12” (30cm) from any television monitor or other radiation-producing, radiation-sensitive  
or heat-producing equipment such as heaters, radiators, etc.  
A1. Shelf/table mounting  
1. Units may be stacked one on top of the other, or with other equipment.  
2. Make sure the rubber feet are firmly attached to the bottom of the unit as shown in Figure 10  
in the Overview section on page 7, and that no ventilation holes are blocked.

1. Remove the mounting screws from the middle  
mounting points as shown in Figure 1.  
2. Screw the left and right mounting brackets on,  
facing downward as shown in Figure 1.  
3. Make sure no ventilation holes are blocked  
when the unit is in place.  
Mounting bracket  
4. Use screws or bolts (not included) to mount the unit in the desired location.  
Note: Make sure that the screws/bolts and mounting surface can support the weight of the unit.  
A3. Rack mounting (For 32-channel, see A4)  
1. Forward facing installation (for easy view of LED indicators):  
a. Remove the mounting screws from the mounting points at the front of the unit.  
b. Screw the mounting brackets onto the front of the unit as shown in Figure 2 or Figure 10.  
2. Backward facing installation (for easy access to terminal blocks and ON/OFF switch):  
a. Remove the mounting screws from the mounting points at the back of the unit.  
b. Screw the mounting brackets onto the back of the unit as shown in Figure 2 or Figure 10.  
3. Find an appropriate unused 1U space in the equipment rack and screw the unit in place.  
4. Leave at least 0.5U above and below the unit for ventilation.  
Note: No rear support rails are needed. The unit can be fully supported using the mounting  
brackets provided.

B. Wiring  
1. Unplug terminal blocks from their sockets for easy installation.  
2. Connect equipment power input cables to the screw terminals side by side in N/P pairs.  
3. Screw the terminals closed. Once done, reinsert the terminal block back into its slot.  
4. Select channel voltage for each terminal block with the switches on the back of the unit.  
5. For each group of channels, select either 24VAC or 28VAC. Switch unused channels to OFF.  
Tech Tip: Group cameras with similar power-cable lengths on the same terminal block and set  
the 24/28 VAC switch to compensate for voltage drops. Test voltage after changing settings.  
Caution: Do not set 28VAC unless voltage drops under 21.5VAC to avoid camera  
damage, etc.  
6. Connect the unit’s power cord to a 120V outlet and switch on the unit.  
7. Front-panel LEDs for channels set to 24 or 28 VAC should glow blue to show output is on.  
8. Test the output at the camera end of each power cable to be sure voltage is correct.  
Caution: Always test output voltage before connecting cameras or other equipment.  
9. For cable management, see page 6. For example applications, see page 7.  
C. Replacing the Main Fuse  
Caution: Replace only with same  
Figure 5  
fuse type and rating.  
1. Find the main fuse at the back of  
Fuse holder  
the unit, between the power cord  
socket and the ON/OFF switch, as  
show in Figure 5 on the right.  
Lever fuse holder  
2. To check or replace the fuse, first power the unit and remove the power cord.  
3. Use a flat-head screwdriver to gently lever the fuse holder out at the place shown in Figure 5.  
Be careful not to damage the soft plastic fuse holder with the screwdriver.  
Tech Tip: There is a spare fuse in the top of the fuse holderuse the old fuse to push it out.  
D. Replacing the Channel Fuses (Glass Fuse Models Only)  
Note: PTC fuses automatically resets when current overload is fixed or removed.  
1. Check if the front panel lock tab has been installed.  
2. If so, remove it following the instructions in the section Using the Front Panel Lock Tab below.  
3. Press on the front panel at the place marked “Push” on the upper middle of the panel.  
4. The panel will click open and swing downward.  
5. Each unit is equipped with spare fuses: 3 for 16-channel models; 6 for 32-channel models.  
6. The spares are found in white fuse holders mounted conveniently on the circuit board.  
Caution: Use caution when replacing fuses in order to avoid shocks or shorts.  
E. Using the Front Panel Lock Tab (Glass Fuse Models Only)  
1. Use the front panel lock tab when greater safety or security is needed.  
2. The lock tab prevents the front panel from being opened accidentally or by unauthorized persons.

pointing up, and turn it down over the front panel.  
F. Cable Management  
1. There are two cable management options included with the product:  
a. Cable management “G” brackets (x2). Screw the brackets onto any of the three mounting  
points on the rear of the unit with the included M3x6 screws. Mount the brackets open end  
at the top, as shown in Figure 8 below or Figure 11 on page 7.  
b. Cable management hooks (x2). Press the white plastic hooks into any of the three mounting  
holes on the rear of the unit as shown in Figure 8 below or Figure 11 on page 7.  
Note: Cable management hooks, once inserted, cannot be removed.  
2. Mount the brackets and route power cables in a way that best suits your installation. Be sure to  
leave slack in the cable to ease future maintenance. Use cable ties to reduce cable tension.  
See example in Figure 8 below.
