INSTALLATION INSTRUCTIONS
ENGLISH
NOTES:
•
For NEMA Type 4X, Type 12 and IP69K applications, enclosure must be mounted by means of mounting feet.
Do not drill or punch any holes into enclosure for mounting purposes.
• Use of a UL Listed Watertight conduit fitting required to maintain the NEMA Type 4X, Type 12 and IP69K ratings.
Leviton conduit hubs
(see Table 1)
are rated for Type 4X and Type 12 applications.
NOTE:
If required, use only a listed/
certified breather drain rated for Type 4X, Type 12 and/or IP69K depending on required environmental application. Drill or
punch a 0.796" (20.2 mm) diameter hole through the bottom of the enclosure at the drill point provided.
•
Mounting feet will accept up to 1/4" (6 mm) screws.
• Drill points provided for conduit entry.
•
When using top or side feed conduit entrance, always form condensation drip loops in wiring as shown.

FEATURES
INSTALLATION
STEPS
1.
Mount Safety Disconnect Switch.
2.
Remove enclosure cover by loosening two cover screws and lifting cover off hinges.
3.
Remove switch
(see REMOVE SWITCH section)
. This is recommended to prevent steel debris from entering switch
components.
4.
Drill or punch conduit hole in desired location(s). See
Table 1
for fitting size.
5.
Install conduit fitting. Ensure "O" ring is properly seated and the inside locking ring is seated tightly against the inside
surface of enclosure to ensure proper grounding.
6.
Re-install switch
(see REPLACE SWITCH section)
.
7.
Connect wires
(see WIRING section)
.
8.
Replace cover and hand thread screws to engagement.
NOTE:
Handle must be in the "OFF" position to close cover.
Tighten screws to 15-18 in.-lbs. (1.7-2.0 N-m) torque.
WARNING AND CAUTIONS
•
WARNING: TO AVOID FIRE, SHOCK, OR DEATH; TURN OFF POWER
AT CIRCUIT BREAKER OR FUSE AND
TEST THAT POWER IS OFF BEFORE WIRING, OR SERVICING DEVICE.
•
WARNING: TO AVOID FIRE, SHOCK OR DEATH,
DISCONNECT ALL POWER
SUPPLIES TO ENCLOSURE
BEFORE EXPOSING INTERIOR
. MORE THAN ONE SUPPLY DISCONNECT MAY BE REQUIRED
TO DE-ENERGIZE THIS EQUIPMENT BEFORE SERVICING.
•
For installation only by an electrician in accordance with the National Electrical Code
®
(NEC
®
), the Canadian Electrical
Code (CEC) and local codes.
•
Separate overcurrent protection must be provided in accordance with the NEC
®
Article 220 or CEC, Section B as
appropriate.
•
Use this device with
copper or copper clad wire only
.
WARNING AND CAUTIONS
• This enclosure includes a lockout provision (in the OFF position) for a suitable padlock. USE ONLY a padlock with
a shackle diameter of 1/4 inch (6.35 mm) to isolate power from the connected equipment in compliance with OSHA
Lockout/Tagout Regulation 29 CFR Part 1910.147.
NOTE:
Lockout feature does NOT interrupt the power supplied to
the switch within the enclosure.
•
Ensure that the rating marked on the device is correct for the intended installation.
• Suitable as Motor Disconnect on a circuit capable of delivering not more than:
- MDS3-AX
- 10kA rms symmetrical amperes, 600V max., when protected by 60A, Class J fuses.
- MDS6-AX
- 100kA rms symmetrical amperes, 600V max., when protected by 100A, Class J or T fuses.
- MDS8-AX
- 100kA rms symmetrical amperes, 600V max., when protected by 100A, Class J or T fuses.
- MDS1-AX
- 65kA rms symmetrical amperes, 600V max., when protected by 100A, Class J fuses.
