16. Protection Features
Output protection Electronically protected against overload, no-load and short-circuits
*)
Output overvoltage protection max. 29.9Vdc in case of an internal power supply defect, a redundant
circuit limits the maximum output voltage. The output
shuts down and automatically attempts to restart.
Input overvoltage shutdown typ. 3x 560Vac 1606-XLE960DX-3N
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 3.5mm e.g. screws, small parts
Over-temperature protection yes output shut-down with automatic restart
Input transient protection MOV (Metal Oxyde Varistor) and active transient blocker
Internal input fuse not included see section 25.4
*) An audible noise may be heard during a no-load, overload or short circuit event.
17. Safety
Input/output separation SELV IEC/EN 60950-1
PELV
double or reinforced insulation
EN 60204-1, EN 50178, IEC 60364-4-41
Class of protection I PE (Protective Earth) connection required
Isolation resistance > 5MOhm input to output, 500Vdc
PE resistance < 0.1Ohm between housing and PE terminal
Touch current (leakage current) typ. 0.40mA 13x480V, 60Hz, TN mains
< 0.45mA 3x524V, 60 Hz, TN mains

Type tests and factory tests:
Conducted by the manufacturer. Do not repeat these tests in
the eld!
Rules for eld test:
Use appropriate test equipment which applies the voltage
with a slow ramp! Connect L1, L2 and L3 together as well as
all output poles.
The output voltage is oating and has no ohmic connection to ground. Grounding of output is allowed.
To fulll the PELV requirements according to EN60204-1, paragraph 6.4.1, we recommend that either + pole or
the – pole be connected to the protective earth system. This helps avoid situations in which a load starts
unexpectedly or cannot be switched o when an unnoticed ground fault occurs.
