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 2000 m (6561.68') 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).
