Mains Supply and Relay Contact Terminals TB2 & TB3

Un = 253Vrms

Hazardous Area Terminals TB1 Terminal Parameters

Uy =12.6V
Ip =87mA
Py = 273mW
C, =0

L, =0

Hazardous Area Terminals TB1 Load Parameters

The capacitance and either the inductance or inductance to resistance ratio (L/R) of the load connected to
hazardous area terminals TB1 must not exceed the following values:

 

 

 

 

 

 

 

 

 

 

 

 

 

GROUP CAPACITANCE INDUCTANCE OR_|L/R RATIO
(uF) (mH) (uH/ohm)
IIc as 46 74
IIB 7A 18.7 298
HA 27 876 596
The above load parameters apply where:
1. The external circuit contains no combined lumped inductance L, and capacitance C; greater than 1%

of the above values.
or 2.

or 3.
with a cable.

The inductance and capacitance are distributed as in a cable.

The external circuit contains either only lumped inductance or lumped capacitance in combination

In all other situations e.g. the external circuit contains combined lumped inductance and lumped capacitance,
up to 50% of each of the L and C values is allowed.

The L/R values shown are the worst case values that allow for a single 8 core cable being used.
