1.2 Fuse Holder Kit
The optional fuse holder kit can be directly installed in the chas-
sis or in the optional subbase. Fuse holder kits are available in
208/230 volt ratings.
Time delay fuses of 15, 20, 25 or 30 Amperes should be used in
accordance with maximum over current protection as displayed
on the unit nameplate.
Installation Procedure(without subbase):
The Installation and servicing of the equipment should be per-
formed by qualified and experienced personnel only.
1) Remove the Front Grille from the unit by pulling it at the bot-
tom on both sides and then lifting upwards as shown in the
figure on the right.
2) To gain access inside the control panel, after removing the
knobs and escutcheon, remove the screws holding the panel
in position. Tilt the panel forward, being careful not to pinch
any wires, as shown in the figure on the right.
3) As can be seen from the front, remove both knockouts off the
control panel and insert the two fuse holders from the front.
The fuse holders should be so connected that the quick con-
nect tabs are facing towards the center of the unit. Attach the
fuse holders using screws and nuts provided.
