FAQ
Common questions
Is the i.safe MOBILE IS940.1 certified for Zone 1?
Yes. The i.safe MOBILE IS940.1 is certified for Zone 1/21 with the marking II 2G Ex ib IIC T4 Gb. Equipment certified for Zone 1 can also be used in Zone 2.
Can the i.safe MOBILE IS940.1 be used in Zone 0?
No. It is not certified for Zone 0. Zone 0 needs equipment with protection level Ga, such as Ex ia intrinsic safety.
What type of explosion protection does the i.safe MOBILE IS940.1 use?
It is intrinsically safe: intrinsic safety (Ex ib). Intrinsic safety limits the electrical and thermal energy in the device below the level that could ignite the surrounding atmosphere.
What does T4 mean for the i.safe MOBILE IS940.1?
Its surface stays below 135 °C, so it is suitable for gases that only ignite above that temperature. Check the ignition temperature of the substances on your site.
Can you charge the i.safe MOBILE IS940.1 in a hazardous area?
Yes, with conditions: yes. Check the certificate's conditions of use before charging on site.
Which ports and accessories can be used with the i.safe MOBILE IS940.1 in the hazardous area?
USB-C and 16-pin ISM covers closed in Ex areas. In Ex areas only these may be connected to the 16-pin ISM: headset IS-HS2A.1, remote speaker microphone IS-RSM3A.1, PTT button IS-PTTB1A.1 (with or without headset IS-HDHS1x.1). The 12-pin dock interface may stay open. Nano-SIM and microSD (IS-SD164.1 / IS-SD1128.1 or cards meeting the entity parameters) allowed in their slots in the Ex area.
