Installation Instruction

1.2. ELECTRICAL INSTALLATION
1.2.1. Health and Safety for Electrical Installation
Read and observe chapter 1.3 Health and Safety.
1. Danger: Electrical hazard. Danger of death or fatal injury from electrical current. Obey all
general and regional installation and safety regulations relating to work on high voltage
installations, as well as regulations covering correct use of tools and personal protective
equipment.
2. Danger: Electrical hazard. Danger of death or fatal injury from electrical current inside the
unit in operation. Before opening the unit, disconnect mains power.
1.2.2. Property Damage Warnings for Electrical Installation
1. Attention: It is compulsory to ground (earth) the unit before connecting the power supply.
A grounding bolt is provided on the cabinet to connect the ground-bonding cable.
2. Attention: If the mains connector of the PSR 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 PSR.
4. Attention: Before connecting or disconnecting the mains connector at the PSR, 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 PSR.
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 cause
damage to the connector and lead to a malfunction of the PSR.
9. Notice: For unstabilized electric networks, which frequently generate spikes, the use of a
voltage limiting device is advised.
10. Notice: Observe the labels on the front panels before connecting or disconnecting any
cables.
11. Notice: Unused connectors must be closed with their protective covers to ensure water
tightness.
