Category D (UL94-V0)
Compressor relay:
more than 175,000 at full load ((16A) 16A)
R290/R600a: EN/IEC 60079-15:2005,
Glow wire according to EN/IEC 60335-1,
IEC/EN 60730, UL60730, NSF, CQC, GOST R 60730
Note: These approvals are only valid when using the
accessories listed in this document
IMPORTANT NOTE
The inputs are not galvanic separated and are connected directly to
the mains supply! For that reason, door-switches, sensors as well as the cables must full the reinforced
insulation requirements.
Safety info
Risk of electrocution!
For mounting: do not connect mains power until the controller is correctly mounted.
For unmounting: disconnect the power supply before unmounting
