Specications

Cover Material UL94 VO (Flame Retardant) Polycarbonate
Hardware 2 qty. 6-32 x ¾" Phillips-drive screws

Notes:

• Insulating Rear Covers cannot be installed over Push Button Reset-Only
Circuit Breaker modules.

• When installed over large source selector rotary switches, covers must be
stacked one on top of another (see Figure 5).

• When installed over meter modules, Systems Monitor 1800, and some
DC modules, an adapter kit is required (see Figure 3).

CAUTIONS

Verify that no DC and AC sources are connected to the vessel’s
electrical system before installing the Insulating Rear Cover.

If an inverter is installed on the vessel, its power leads must
be disconnected at the battery before the Insulating Rear Cover
is installed.

If an AC generator is installed on the vessel, it must be stopped and
rendered inoperable before installing the Insulating Rear Cover.

For AC/DC combination panels, ABYC compliance requires that
when the panel is open, there can be no access to energized AC
parts without the use of tools (ABYC E11.11.1.1). To comply, Insulating
Rear Covers should be installed over AC circuitry.

USCG compliance requires that DC circuitry, not protected by a fuse or
circuit breaker, must have a boot or an Insulating Rear Cover (Code of
Federal Regulation 183.445).

Installation

1. To reduce the risk of electrical shock, disconnect all AC and DC power before installation. This includes inverters, generators, shore power attachments, and any
other device capable of supplying AC or DC power to the vessel’s circuits.

2. Place insulating cover(s) over module(s) to be insulated, aligning captive mounting screws in cover with threaded mounting holes in subframe.

3. Mark which breakouts are to be removed for wires to pass through cover. NOTE: Holes can be drilled in cover instead of removing breakouts.

4. Remove insulating cover, score along selected breakouts with a utility knife, and bend to remove breakouts (see Figure 6). IMPORTANT! For safety, slot or hole
size should be close to the diameter of the wire passing through the cover.

5. Replace insulating cover(s) over module(s) and fasten using captive mounting screws.

Installing Insulating Rear Cover Over Meter, Systems Monitor 1800, and Some DC Modules

NOTE: When installing insulating cover over meter, Systems Monitor 1800, and some DC modules, an adapter kit (PN 4118) is required.

1. Remove 4 Phillips at head bezel mounting screws from subframe.

2. Using longer screws provided in Adapter Kit, attach adapters to subframe. Screws pass through adapters and subframe, and thread into bezel mounting holes.

3. Mount insulating cover as described in steps 2 through 5 above.

replaced with longer screws
used to attach adapters.

Install adapters with threaded
mounting holes toward the
outside edges of module.
