3.2. ELECTRICAL INSTALLATION
3.2.1. General
Read the health and safety warnings in chapter 1.2.
1. This unit contains dangerous voltages. Loss of life, severe personal injury or
property damage can be the result if the instructions contained in this manual are
not followed.
2. It is compulsory to ground the unit before connecting power supply. A grounding
bolt is provided on the cabinet to connect the ground-bonding cable.
3. Although the Remote Unit is internally protected against overvoltage, it is strongly
recommended to earth the antenna cables close to the antenna connectors of the
Remote Unit for protection against atmospheric discharge. In areas with strong
lightning it is strongly recommended to insert additional lightning protection.
4. If the mains connector of the Remote Unit is not easily accessible, a disconnect
device in the mains circuit must be provided within easy reach.
5. Before connecting or disconnecting the mains connector at the Remote Unit,
ensure that mains supply is disconnected.
6. Make sure that an appropriate branch circuit breaker and an overcurrent limiting
device are connected between mains and Remote Unit.
7. An external circuit breaker is mandatory as disconnect device. This circuit breaker
should be readily available for the operator.
For the U.S. and Canada, installation has to be done in accordance with the NEC
(National Electronic Code). The external circuit breaker has to be a branch circuit
breaker rated 20 A for 110 Vac mains.
8. A field wiring box with conduit must be used for the installation. Use a wire
harness rated for AC mains with at least AWG14 size.
9. A connection of mains supply to a power socket requires the power socket to be
nearby the Remote Unit.
10. Incorrectly wired connections can destroy electrical and electronic components.
11. 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).
12. Use an appropriate torque wrench for the coupling torque (25 N-m / 19 ft lb) of
7/16-DIN connectors with 1 ¼-inch opening to tighten the 7/16-type antenna
connectors. For example, use torque wrench of item no. 244377 available from
the Andrew e-catalog. 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 Remote Unit.
