52 MPR-e and MSS-1c User Manual 3DB19901EFAA Edition 01
The following sections describe necessary information to avoid equipment damage.
2.7.1 — Anti-static protection device kit
Whenever it is necessary to handle spare parts and cards out of the box, an anti-static
protection device kit (Figure 2.4) must always be worn and terminated at a grounded
structure, to avoid possible damage to the electronic devices by electrostatic discharges.

2.7.2 — Screw fixing
Under normal operating conditions, all screws (such as for unit box closing and cable
fixing) must always be tightened to avoid item detachment and to ensure equipment EMI-
EMC performance.
The screw tightening torque must be:
• 2.8 kg x cm (0.28 Newton x m) ±10%
• 2.4317 in lb (0.2026 ft lb) ±10%
Exceeding these values may result in the screw breaking.
2.7.3 — Cable disconnection / connection
Before disconnecting or connecting the cable (at the indoor or ODU side), switch off the
corresponding MSS-1c or MPR-e unit.
