2.4.3 Overcurrent Protection – AUX PWR (Universal - High Range Power

Supply)

To maintain the safety features of this product an external fuse shall be provided at the

AUX PWR supply input and must be connected in series with the ungrounded/non-

earthed (hot) side of the supply input terminals prior to installation.

For UL/CSA, Bitronics recommends a UL 248-4 certified fuse, Class CC, rated 600

Vac/300 Vdc, 3 Ampere time delay (T) fuse (such as Littelfuse CCMR003 or Mersen

ATDR3).

For CE, Bitronics recommends a fuse certified to IEC 60127-2 Sheet 3, rated 250 Vac

(min or greater), 3.15 Ampere time delay (T) fuse.

The fuse shall additionally be enclosed in an appropriate fuse holder to prevent the

possibility of a fuse shattering and spraying metal pieces. The fuse and fuse holder

must carry a voltage rating that is appropriate for the power system on which it is

being used.

2.5 Supply/Mains Disconnect – AUX PWR (Universal – Hi Range Power Supply)

Equipment shall be provided with a Supply/Mains Disconnect that can be actuated by

the operator and simultaneously open both sides of the mains input line. The

Disconnect should be UL Recognized in order to maintain any UL product approval.

The Disconnect should be acceptable for the application and adequately rated for the

equipment.

The instrument may be mounted on a 19" Rack panel if desired. Two PPX II units will

fit side by side on a standard 5.25" high (3U) panel. See Figure 2 for dimensions. The

unit should be mounted with four #10-32 (M4) screws. Make sure that any paint or

other coatings on the panel do not prevent electrical contact.

Cleaning the exterior of the instrument shall be limited to the wiping of the instrument

using a soft damp cloth applicator with cleaning agents that are not alcohol based, and

are non-flammable and non-explosive.
