The manual provides a "Temperature Alarm" example: M91-t4-r6-zk1 Manual

Section 4 of the M91-t4-r6-zk1 Manual is dedicated to physical installation. This is the most critical part, as incorrect wiring can permanently damage the unit.

Q1: Can I use the M91-t4-r6-zk1 outdoors?
Yes, the t4 rating includes weather resistance. However, the manual specifies IP20 protection; an external NEMA 4X enclosure is required for direct rain or dust.

Q2: Why does my M91-t4-r6-zk1 get warm even when no outputs are active?
Normal. The internal voltage regulator dissipates ~3W of heat. Operating temperature should not exceed 70°C on the housing. The M91-t4-r6-zk1 is designed for DIN rail mounting

Q3: Is the zk1 module compatible with other Zigbee hubs?
Only with the manufacturer’s own Zigbee coordinator (model ZC-100). The manual notes that the ZK1 uses a proprietary application profile; generic hubs will see the device but cannot parse data.

Q4: I lost my manual. Can I request a replacement?
Yes. Contact technical support with the serial number (found on the side label, format M91-xxxxx). A PDF will be emailed within 24 hours.

The M91-t4-r6-zk1 is designed for "fit and forget" operation, but the manual recommends: Before attempting to operate the device, use the
