Precautions
WhenusingtheH3RNinanyplacewheretheambienttemperature
is more than 50"C, supply 90% to 110% of the rated voltages (at
12 VDC: 95% to 110%).

not secured, the ambient temperature must be less than 50"C.
The internal parts may become damaged if a supply voltage other
than the rated ones is imposed on the H3RN.
Precautions for VDE Conformance
The H3RN as a built-in timer conforms to VDE 0435/P2021 pro-
vided that the following conditions are satisfied.
Handling
Do not touch the DIP switch while power is supplied to the H3RN.
Before dismounting the H3RN from the socket, make sure that no
voltage is imposed on any terminal of the H3RN.
Wiring
Onlyaloadwithbasicisolationcanbeconnectedtotheoutput con-
tact.TheH3RNisamodelwithbasicisolation.Therefore,theH3RN
and the load will ensure reinforced isolation, thus meeting VDE
standards.
Insulation requirement: Overvoltage category II,
pollution degree 2
(with a clearance of 1.5 mm and a creep-
age distance of 2.5 mm at 240 VAC)
