Mechanical environmental conditions

The housing is resistant to general atmospheric contamination.
Resistant to gas engine oils.

Panel Mount Version:
Protection class: I, Protection: IP20

Light Duty Version:
Protection class: I, Protection: IP69

Heavy Duty Version:
Protection class: I, Protection: IP69

The specified protection classes and types are only guaranteed if all external wiring connections are made in accordance with the connector specification, all covers and seals are installed as intended and the following tightening torques are observed:

  • All M4 bolts: 0.8 Nm to 1 Nm (0.6 lb-ft to 0.7 lb‑ft)
  • PG screw joints: 4.5 Nm to 5 Nm (3.3 lb-ft to 3.6 lb‑ft)
  • Service screw: 2.5 Nm to 3 Nm (1.9 lb-ft to 2.2 lb‑ft)

Always use a new seal when installing the service cover.

Standard single seal inserts for PG screw joints (Heavy Duty and Light Duty Version)

Suitable for a cable with a diameter of 6 mm to 13 mm.

Multiple seal inserts for PG screw joints (Heavy Duty and Light Duty Version)

Suitable for up to three cables, each with a diameter of 6 mm to 7 mm.

Climatic environmental conditions

Panel Mount Version:
–20 °C to +50 °C (–4 °F to +122 °F)

Light Duty Version:
–40 °C to +60 °C (–40 °F to +140 °F)

Heavy Duty Version*:
–40 °C to +70 °C (–40 °F to +158 °F)

Max. 85 % humidity without condensation up to 3,000 m (9,842') above sea level

 

Determining Maximum Ambient Temperature for Heavy Duty Version

* The maximum ambient temperature for the Heavy Duty Version of the MIC4 is dependent on the net power delivered. This can be up to +80 °C (+176 °F) for low net power.

Net power

Max. ambient temperature

18 W

+80 °C (+176 °F)

36 W

+75 °C (+167 °F)

54 W

+70 °C (+158 °F)

 

Determine the maximum ambient temperature for the Heavy Duty Version of the MIC4 as follows:

1. Determine the net power (P) delivered.

 

Engine type

Max. ambient temperature

 

Two-Stroke Engine

04__Formel1

 

Four-Stroke Engine

04__Formel2

Notice:
Energy refers to the set energy limit (see Timing – Schedule A/B – Energy). The number of outputs refers to the configured outputs.

 

2. Calculate the maximum ambient temperature.

Max. ambient temperature in °C = 80 – (P – 18) x 5 /18
The formula is defined for P ≥ 18 W. The ambient temperature is therefore limited to +80 °C (+176 °F).
