WARNING Potentially lethal voltages can be induced if the equipment is not grounded correctly.
W arnings after the AC power outlet is disconnected! WARNING Do not rely on the power switch alone to isolate a supply. Unplug the power supply cable from the mains socket if possible. 2.3 Weight WARNING The MU weighs 16.5 kg (33 lb.) without the cover and mounting frame. The three types of Remote Unit (RU) vary in weight between 1.7 kg (3.8 lb) and 11 kg (24.25 lb). The Centralised Power Supply Unit (CPSU) weighs 12.5 kg (27.5 lb). 2.

Caut ions 3 Cautions 3.1 Handling of MU, RUs and the CPSU 3.1.1 Storage and transportation Caut ion During storage and transportation, the MU, RUs and the CPSU (if used) must remain in the original packaging to: • Avoid mechanical damage • Maintain traceability • Protect the units against static electricity (ESD precaution). Caut ion Handle the MU, RUs and the CPSU (if used) with care. Do not drop the product or the package containing it. 3.1.
W arnings and Caut ions 3.1.3 Handling the MU Caut ion Do not lift the MU by the splice cassette box because the cassette or the cassette box may break. Caut ion Take care not to damage the door switch of the MU when lifting the MU. 3.1.4 Installation of the MU, CPSU and the RUs Caut ion Installation of the MU and CPSU above a height of 2 meters is not recommended due to the difficulties of installing and maintaining the units above this height.
Caut ions The MU contains Electrostatic Sensitive Devices (ESD) label and stud, which means that they may be permanently damaged by electrostatic discharges encountered in routine handling, testing and transportation. The MU is labelled with an electrostatic sensitive device symbol as shown in Figure 7. F igure 7. El ect rost at ic sensit ive device l abel Electrostatic discharges are caused by direct contact or by an electrostatic field.

Caut ions 3.2.1 MU 3.2.1.1 MU AC power supply Caut ion Ensure the correct polarity. Incorrect polarity causes damage to the equipment. Caut ion The MU power switch does not disconnect the equipment from the power network. The separate main switch on the site is considered a disconnect device for safety and service purposes. Alternatively, the power supply cable can be unplugged from the mains socket.
W arnings and Caut ions 3.2.2 RU RUs using -48 VDC require a CPSU. Caut ion RUs can be used with 110 VAC or 220 VAC or -48 VDC. However the 110/220 VAC and -48 VDC supplies are connected via different connectors. The required type of RU (110/220 VAC or -48 VDC) must be specified at the time of ordering.
