93%
(non-condensing)
c) DO NOT loca te th e e quipment w here i t is ex posed to high
levels of moisture.

1.3 Transient
protection
As with all solid state devices, this system may operate erratically
or c an be damaged i f sub jected to li ghtning-induced t ransients.
This equipmen t contains trans ient p rotection devic es. Al though
no system is immune from lightning transients and interference,
for thes e devices to func tion co rrectly, and to reduc e
susceptibility, this equipment must be earthed correctly.
The use of overhead or outside aerial wiring is not recommended
due to the increased susceptibility to nearby lightning strikes.
The HLS PS Series is wall mounted in a position, which allows
clear v isibility of ind icator leds. The he ight above fl oor le vel
should be chosen such that t he indicators are just above normal
eye level (approximately 1.5 metres).
1.4 Cleaning
The HLS PS Series case may be clean ed periodically by wiping
with a soft, damp lint-free cloth.
Do not use solvents.
