WIRING DIAGRAM
Notes:
1. ALARM RELAY A can be programmed as ALARM or ALARM FAIL SAFE (default setting) or
TRIPPING/ALARM.
TRIP RELAY B can be programmed as TRIP (default setting) or TRIP FAIL SAFE or
TRIPPING/ALARM.
Refer to section
6.2 Parameter Setting – I/O Settings page 12 for more information.

Warning
: The analog output circuit is isolated as a group together with the RS-485 communication.
When using both connections, verify that analog out user (or RS-485 user) is using an isolated
circuitry.
Connect all shield wires to ground (a short busbar may be used)
3.
Relays Contacts
:
Rated load:
8A/250 VAC (VDE, UL, cUL); 8A/24VDC (UL, cUL).
Maximum breaking capacity AC:
2000 VA
Max. DC Load Breaking Capacity:
8A at 30VDC.

DANGER
- Electrocution Hazard - RTDs or other sensors connected to this device must be provided
with electrical isolation sufficient for the voltage present on the motor windings (or other equipment
being monitored). Sensors must also be provided with shielded cables, and all shields must be reliably
grounded.
