1. Attention: It is compulsory to ground (earth) the unit before connecting the
power supply. Grounding bolts are provided on the cabinet to connect the
ground-bonding cable.
2. Attention: If the mains connector of the Remote Unit is not easily accessible, a
disconnect device in the mains power circuit must be provided within easy reach.
3. Attention: A connection of the mains supply to a power socket requires the
power socket to be nearby the Remote Unit.
4. Attention: Before connecting or disconnecting the mains connector at the
Remote Unit, ensure that mains power supply is disconnected.
5. Attention: Make sure that an appropriate circuit breaker acting as a disconnect
device (as required by IEC/EN60950-1) and an overcurrent limiting device are
connected between mains power and the Remote Unit.
6. Attention: Incorrectly wired connections can destroy electrical and electronic
components.
7. Notice: To avoid corrosion at the connectors caused by electrochemical
processes, the material of the cable connectors must not cause a higher potential
difference than 0.6 V (see electrochemical contact series).
8. Notice: Use an appropriate torque wrench for the coupling torques:
- for 4.3-10 type connectors (5 Nm, 44 in lb) with 22mm (7/8) in opening,
e.g. item no. TW-4310
Do NOT use your hands or any other tool (e.g. a pair of pliers). This might
