- VERIFY ISOLATION FROM THE SUPPLY
- EARTHING AND SHORT-CIRCUITING
- COVERING OR PROVIDING BARRIERS TO ADJACENT LIVE PARTS DISCONNECT THE EQUIPMENT FROM THE SUPPLY. USE ONLY AUTHORIZED SPARE PARTS IN THE REPAIR OF THE EQUIPMENT. THE SPECIFIED MAINTENANCE INTERVALS AS WELL AS THE INSTRUCTIONS FOR REPAIR AND EXCHANGE MUST BE STRICTLY ADHERED TO PREVENT INJURY TO PERSONNEL AND DAMAGE TO THE SWITCHBOARD.
General information
The IP55 dust and water-resistant cover is a translucent hinged dome-shaped
cover that attaches to the metal compartment door (panel) to provide dust and
water protection for a drawout or fixed circuit breaker in keeping with the
IP55 code. The specific code defines the degree of protection against the
ingress of solid foreign objects and water.
Note: The IP55 cover is used in conjunction with a door escutcheon, which is a
molded frame and gasket used to seal the space between the circuit breaker and
the compartment door cutout. If an escutcheon is not already installed, an
escutcheon kit will have to be installed before the IP55 cover can be used.
Refer to IL01301012E for door escutcheon installation details.
Note: The existing enclosure must qualify to IP55 requirements for dust
and water environments.
Required tools
- Phillips head screwdriver (#2 recommended)
- Drill
- 0.265-inch (6.5 mm) drill bit
- Small adjustable wrench
Kit parts identification
Refer to Figure 1 for visual identification of the parts listed below.
- (A) IP55 cover with captive hardware (one)
- (B) Hinge pin (one)
- (C) Hinge block (two)
- (D) Hex standoff (NF – two; RF – four)
- (E) M6 x 20 screw (four)
- (F) M6 x 8 screw (NF – two; RF – four)
- (G) M6 hex nut (four)
- (H) M6 split-ring lock washer (four)
Installation of IP55 cover
Step 1: Locate and drill the 0.265-inch (6.5 mm) diameter mounting holes
in the compartment door (panel) relative to the already mounted door
escutcheon as shown. Two holes are required for the NF frame
and four holes are required for the RF frame.
Note: The exact mounting hole locations are determined by whether the
circuit breaker is a fixed or drawout configuration.
Step 2: Mount the hex standoffs (D) using M6 x 8 mm screws (F) from behind the compartment door (panel), using the holes from Step 1.
Step 3: Mount the lexan IP55 cover (A) to the hex standoffs installed in Step 2, using the captive hardware in the IP55 cover. This will ensure accurate positioning of the hardware to be installed next in Step 4.
Step 4: Align the lower hinge block (C) by centering hinge pin hole in the end of the hinge block with the hinge pin channel of the IP55 cover. The hinge block should be flush with the hinge channel of the cover. Use the two mounting holes of the block as a template to locate the placement of two 0.265 (6.5 mm) diameter holes in the compartment door (panel). Mount the lower hinge block using two M6 x 20 screws (E), M6 hex nuts (G) and M6 washers (H). The hex nuts and washers are positioned behind the compartment door (panel). Repeat the same procedure to mount the top hinge block, while capturing the hinge pin (B) in the end holes of the lower and upper hinge blocks.
Note: The IP55 cover is shown open in Figure 6 below for clarity purposes.
