must be prohibited near battery. In addition, it is recommended to prohibit smoking in
all areas where equipment is placed.
l
The lab must comply with national Level 2 fire protection standard.

3.3 Power Supply Requirements Inspection

l Nominal voltage of power supply provided for ZXR10 ZSR router by power device in
lab is -48V and the allowed variation range is -57V~-40V.
Noise level index of the DC voltage must comply with general technical specifications
issued by the former MPT.
DC power supply must have over-voltage/over-current protection and indications.
l
AC Power Supply Requirements
100V~240V, 50Hz~60Hz, wave distortion <5%.
Voltage frequency requirements to standby electric generator are same as those listed
above but its wave distortion range is 5%~10%.

3.4 Grounding Inspection

Ground wires in the lab must be laid radially or in plane mode and ground wires must be
laid separately. Electric circuits formed by reinforcing steel bars used in the building or
through cabinet are not allowed.
In case of compound grounding, the earthing resistance must be less than 1Ω. The
cross-sectional area of grounding wire is determined by the Max permissible current. The
grounding wire must be sheathed copper wire instead of bare copper wire.

3.5 Auxiliary Equipment Inspection

l
