SAFETY PRECAUTIONS
SPECIAL CONDITION FOR SAFE USE
1. The equipment must be protected with earth
leakage protective device or insulation monitoring
device, dependent on the type of system earth,
according to IEC 364-3, Chapter 31, CENELEC
EN 50019:2000, Annex D., and Canadian Electrical
Code, Section 62, Rule 62-300 (either as pt. 1 or
pt. 2 below):
1. A A residual current protective device with a rated
residual operating current not exceeding 300 mA
should be used. Preference should be given to
protective devices with a rated residual operating
current of 30 mA. The protective device should
have a maximum break time not exceeding 5 s
at the rated residual operating current and not
exceeding 0,15 s at 5 times the rated residual
operating current.
2. An insulation monitoring device should be used
to disconnect the supply whenever the insulation
resistance is lower than 50 Ω/ V of rated voltage.
2. A The heating unit must be terminated in a suitable
certified terminal enclosure or in safe area.
2. B The heater unit with permanently connected
unterminated cable need an appropriate protection
of the free end of the cable.

The enclosure heater must not be tested with or
terminated to (1000+2Un) V r. m. s. (e. g. 1500 VAC), where
Un is the rated voltage. Only DC (direct current) of max.
2550 VDC is acceptable for testing of electrical insulation
resistance between lead wires and braid.
