MF0123A1A PSR 700/800 MHz
4.2. Electrical Installation
4.2.1. Health and Safety for Electrical Installation
Read and observe chapter 1.2 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.
4.2.2. 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.
