form to all local codes.
2. Unless the unit is specifically marked as a NEMA Type 3, 3R, 3S, 4, 4X, 6, or 6P en-
closure, it is designed for indoor use only and must not be installed where exposed to
rain and moisture.
3. Only use replacement parts Pelco recommends.
4. After replacing/repairing this unit’s electrical components, conduct a resistance mea-
surement between line and exposed parts to verify the exposed parts have not been
connected to line circuitry.
The product and/or manual may bear the following marks:
This symbol indicates that danger-
ous voltage constituting a risk of
electric shock is present within this
C A U T I O N :
unit.
RISK OF ELECTRIC SHOCK.

This symbol indicates that there
are important operating and main-
tenance instructions in the litera-
ture accompanying this unit.
Please thoroughly familiarize yourself with the information in this manual prior to installation
and operation.
DESCRIPTION
The MCS*E Series consists of multi-output 24 VAC indoor power supplies. These power
supplies provide output for 4, 8, or 16 cameras from a single source and come in 2, 5, 10,
and 20 amp capacities. The power supplies allow for 120 VAC line input. Higher capacity
models can handle pan and tilt and receiver operation, in addition to the camera, for inte-
grated systems such as Spectra® and Esprit™.
All MCS*E Series models come with an individual glass fuse for each output channel.

MCS*E Series Power Supply
Spare fuses
Wire nuts
To install an MCS Series power supply, perform the following steps:
1. Decide where to install the unit.
2. Open the lid on the unit by removing the 8-32 Phillips screw.
3. Drill holes in the mounting surface. Use the unit as a template.
4. Attach the unit securely with four fasteners (not supplied) of the appropriate length.
You can use fasteners up to 5/16-inch (0.80 cm) in diameter.
5. Punch out the necessary knockouts. (There are six knockout holes on the top and two
on the bottom.)
6. Install 1/2-inch (1.27 cm) or 3/4-inch (1.91 cm) conduit fittings where necessary (con-
duit fittings not provided).

1. Verify that the on/off switch inside the box is OFF.
2. Remove the high voltage compartment panel inside the box.
3. Attach the 120 input wires to the flying leads in the compartment with the supplied
wire nuts (Brown – AC Line; Blue – AC Neutral).
4. Attach the input ground wire to the stud inside the compartment with the supplied
washer and nut.
5. Replace the access panel.

OUTPUT CONNECTIONS
Perform the following steps to attach 24 VAC devices to the MCS*E Series power supply:
1. Refer to Tables C and D in this manual or the wiring table on the unit’s lid to determine
the output connection needed for your devices.
2. Refer to Figure 1 for the proper connector strip connections.
3. For each device, attach one output wire to the common terminal. Attach the second
wire to the appropriate 24 VAC terminal.
4. When you finish the wiring connections, double check the installation for safety pur-
poses.
5. Power up the unit with the on/off switch.
6. Use a voltmeter to verify that used outputs are at appropriate voltage levels.
7. Close the lid and secure it using the 8-32 Phillips screw.

Table C. Recommended Wiring Distances
The following are the recommended maximum distances (transformer to load) and are calculated with a 10-percent voltage drop.
(Ten percent is generally the maximum allowable voltage drop for AC-powered devices.) Distances are calculated in feet; values in
parentheses are meters.

You can use Table D as a guide to determine the necessary wire gauge (AWG) for various cable distances that provide 24 VAC
power. Or use it in a reverse fashion to determine the maximum allowable cable distance for a particular wire gauge. Table D applies
when using 2-conductor copper wire, with characteristics similar to West Penn 221-227 unshielded cable. Calculations are based on
a 10-percent voltage drop (generally the maximum allowable drop for AC-powered devices).
The minimum acceptable voltage is calculated as follows:
24.0 VAC
– 02.4 (10%)
21.6 (Minimum Acceptable Voltage)
The minimum acceptable voltage used to create Table D was 21.6 volts. Therefore, the 24-volt output has an acceptable range from
24 volts down to 21.6 volts.

MAINTENANCE
There are no user-serviceable parts except for the fuses. If the transformer in the unit does
not work properly, the entire power supply needs to be returned to the factory for repair. Re-
fer to the Warranty and Return Information section of this manual for instructions on return-
ing the power supply for repair.
Clean the outer surface of the power supply with a nonabrasive cleaning cloth and anti-
static cleaner. Do not use kerosene or similar substances that may damage the surface.
