1. This floor stand should be used when EC fans are intended to be lowered under a raised floor. The standard floor stand can be used if the fans are to remain raised. 2. Right side of paneled unit is flush with right side of floor stand. All other paneled sides

overhang floor stand 1" (25mm).

3. The floor stand used with EC units is not symmetrical and its orientation to the Liebert DSE is critical for lowering the EC fans. Unless the floor stand is installed in the correct position, the blowers will not lower into the floor stand.

4. Jack and jack support are shipped loose and are intended to be placed into position under each fan and used to lower or raise that fan as needed.

3. The floor stand used with EC units is not symmetrical, and proper orientation required for lowering

the blowers. The blowers will not lower into the floor stand unless the floor stand is installed in the correct position. 4. The jack and jack support are shipped loose and are intended to be placed into position under each fan

Electrical Connections

8.1

Standard Electrical Connections—Liebert MC

(Source: DPN002169, Rev. 7, Page 1)

1. Three-Phase Electrical Service—Terminals are on top of the disconnect switch for one- and two-fan units. Terminals are on the bottom for the disconnect switch for three- and four-fan units. Three-phase service is not provided by Emerson (See Note5 on page 38.)

2. Earth Ground—A field lug terminal is available for earth ground connection. Ground the terminal strip to make a fan motor ground connection.

3. Primary High Voltage Entrance—Two knockouts, each 7/8" (22.2mm) diameter, at the bottom of the enclosure.

4. Surge Protection Device (SPD) Field Connection Terminals—High-voltage surge

protective device terminals. (SPD is optional.)

5. CANbus Terminal Connections—Terminals for field CANbus cable connection.

a. 5A is the CANbus connectors

• TB49-1 is the input terminal for CANbus high. • TB49-3 is the input terminal for CANbus low. • TB50-1 is the output terminal for CANbus high. • TB50-3 is the output terminal for CANbus low.

• Each CANbus cable shield is connected to Terminal SH, (see Item9). b. 5B is the END OF LINE jumper

c. 5C is the CANbus device address DIP switch. This CANbus cable is not supplied by Emerson (see Note2 on page 38).

6. Remote Unit Shutdown—Replace existing jumper between Terminals TB38-1 and TB38-2 with

field-supplied normally closed switch having a minimum 75VA, 24VAC rating. Use field-supplied Class 1 wiring. (This is an optional feature that may be owner-specified.)

7. Alarm Terminal Connections

a. The Common Alarm Relay indicates when any type of alarm occurs. TB74-1 is common; TB74-2 is normally open; and TB74-3 is normally closed. 1A, 24VAC is the maximum load. Use field-supplied Class 1 wiring.

b. The Shutdown Alarm Relay indicates when a condenser loses power or when a critical alarm has occured that shuts down the condenser. TB74-4 is common; TB74-5 is normally open; and TB74-6 is normally closed. 1A, 24VAC is the maximum load. Use field-supplied Class 1 wiring.

8. Indoor Unit Interlock and SPD Alarm Terminals

a. On any call for compressor operation, normally open contact is closed across Terminals 70 and 71 for Circuit 1; and from an indoor unit, normally open contact is closed across Terminals 70 and 230 for Circuit 2.

b. During an SPD alarm, the normally open contact is closed across Terminals 12 and 13. (SPD is an optional device.)

9. CANbus Shield Terminal—This terminal is for the field connection of the field-supplied CANbus cables. The shield of the field-supplied CANbus cables must not be connected to ground. 10. Primary Low-Voltage Entrance—One knockout, 7/8" (22mm) diameter, free for customer

low-voltage wiring.

11. Surge Protection Device Entrance—One knockout, 7/8" (22mm) diameter, at the bottom of the enclosure. (High-voltage SPD is an optional device.)

Notes on Electrical Connections—Liebert MC

(Source: DPN002169, Rev. 7, Pages 2-3)

1. Refer to specification sheet for the unit voltage rating, full load amp and wire size amp ratings. 2. The CANbus wiring is field-supplied and must be:

• Conductors 22-18AWG stranded tinned copper • Twisted pair, minimum four twists per foot (305mm) • Braided shield or foil shield with drain wire

• Shield must be wired to ground at the indoor unit • Low capacitance (15pF/FT or less)

• UL-approved temperature rated to 167°F (75°C) • UL-approved voltage rated to 300V

• UV-resistant and moisture-resistant if not run in conduit

• Plenum-rated NEC-type CMP, if required by national or local codes

Examples: Belden 89207 (plenum-rated) or Alpha Wire 6454 (UV resistant outdoor rated) Category 5, 5e or higher

3. Do not run the CANbus cable in the same conduit, raceway or chase as high-voltage wiring. 4. No special considerations are required when the total external cable connection between the

indoor unit and outdoor unit(s) is less than 450 ft. (137m). A CANbus isolator is required for total external cable connections greater than 450 ft. (137m) but less than 800 ft. (243m).

5. All wiring must be sized and selected for insulation case per National Electrical Code and other local electrical codes.

6. Do not bend cables to less than four times the diameter of the cable.

7. Do not deform cables when securing them in bundles or when hanging them.

8. Do not run cables near devices that may introduce noise, such as machines, fluorescent lights and electronics.

9. Do not stretch cables.

NOTICE

Risk of CANbus communication interference. Can cause improper operation.

Separate high voltage wires and other high voltage sources from CAN wires by 12 inches (305mm).

NOTICE

Risk of improper input power. Can cause equipment damage.

The Liebert MC is designed to operate with wye-connected power with a solidly grounded neutral. It will not operate properly with wye-connected power with high-resistance (or impedance) ground or with delta-connected power

Acceptable Power Supplies for Liebert MC—208 to 575V Nominal Units

Source: DPN002374, Pg. 3, Rev. 6

• 208V wye with solidly grounded neutral and 120V line-to-ground • 380V wye with solidly grounded neutral and 220V line-to-ground • 480V wye with solidly grounded neutral and 277V line-to-ground

• 575V wye with solidly grounded neutral and 332V line-to-ground (with step-down transformer)

Unacceptable Power Supplies for Liebert MC—480V Nominal Units

Source: DPN002374, Pg. 3, Rev. 6

• Wye with high-resistance (or impedance) ground • Delta without ground or with floating ground • Delta with corner ground

Component Notes:

1. Component appearance, orientation and position may vary between product lines. Terminal names and callouts remain constant. Cable Notes (A, B, C):

1. Field-supplied cable: ● shielded

● 24-18AWG stranded tinned copper ● twisted pair (minimum 8 twists per foot) ● low capacitance (15pF/ft or less)

● must be rated to meet local codes and conditions. ● examples Belden 89207 (plenum-rated), or Alpha Wire 6454 Category 5, 5e or higher.

2. Do not run in same conduit, raceway or chase as voltage wiring.

3. Contact factory for CANbus network lengths greater than 350ft (107m).

Wire Notes (F, G,H): 1. Field-supplied wire: ● 18AWG or greater ● rated 600V

2. For single-circuit systems, run two wires from indoor unit to condenser(s).

3. For dual-circuit systems, run three wires from the indoor unit to first condenser and one wire from first condenser
