Conditions of acceptability

When installed in the end-use equipment, consideration shall be given to the following:

1 - A suitable enclosure shall be provided in the end-use application.

2 - The insulation between the primary and the secondary sensing circuits were evaluated with 4250 V AC for CTSR 0.6-TP/

SP and 2200 V AC for CTSR 0.6-P in dielectric voltage withstand test.

5 - CTSR series is intended to be mounted on the printed wiring board of the end-use equipment.

7 - The uninsulated live parts of primary feeder and secondary circuit clearance spacing of Model CTSR XX-P series shall

maintain at least 5.5 mm apart.

8 - Primary feeder of the devices shall be connected after an overvoltage device or system which has been evaluated by the

Standard for Transient Voltage Surge Suppressors, UL 1449.

Marking

Only those products bearing the UL or UR Mark should be considered to be Listed or Recognized and covered under UL's

Follow-Up Service. Always look for the Mark on the product.
